The smell hits you on the stairs before you reach the door. Cocoa nibs roasting somewhere in the back, vanilla, and the bitter edge of an Ecuadorian 80% bar that someone has just broken open for the next group. By the time you’ve climbed the last step into the Cranston Street building, your mouth is already watering and the tour hasn’t started.
This is the booking-side guide to The Chocolatarium, an artisan-chocolate workshop and tasting attraction tucked just off the Royal Mile. The tour itself is fixed at 90 minutes and there is really only one product, so most people just need to pick a date and go. But there are a few things worth knowing about timing, allergens, kids’ age limits, and which of the two Edinburgh booking platforms is actually the smoother choice.
It also pairs surprisingly well with the city’s better-known whisky and food tours, which is where the real itinerary planning kicks in. More on that below.

In a Hurry? Three Picks
Best chocolate tour: The Chocolatarium Chocolate Tour Experience from $44 per person. 90 minutes, kids 6+, decorate your own bar to take away.
Pair it with whisky: The Scotch Whisky Experience Tour and Tasting from $33. Same Royal Mile, totally different sensory direction.
Make a half-day of food and drink: Edinburgh Food and Drink Tour with Eat Walk Tours from $164. Three hours, walking, haggis to whisky.
What the tour actually is
The Chocolatarium runs one product and runs it well: a 90-minute guided tour through three rooms, with tasting and a hands-on chocolate-making segment built in. It is not a passive museum visit. You are sat down, handed samples, asked to compare flavours, then walked through a working kitchen where someone makes a small batch in front of you.
The structure breaks down roughly like this. First comes a fifteen-minute intro on the history of cacao: how the Aztecs drank it, how the Spanish ruined it with sugar, how Fairtrade actually plays out for the cacao farmers in West Africa today. Then you move to the Chocolate Kitchen, where the equipment is real and the guide demonstrates roasting, conching, and tempering. Finally you head to the tasting room.
Tasting is the part most people remember. You get to try at least a dozen varieties, ranging from single-origin dark chocolates (Madagascar, Venezuela, Ecuador all turn up regularly) through to Scottish-made hand-crafted bars. The guide walks you through what to look for: snap, melt, the order in which flavours land on your tongue. Bring an appetite. By the end you’ll have eaten more chocolate than you would in a normal week.
The last room is where you make your own bar. You pick a mould (Edinburgh Castle, thistle, simple bar shape, a few seasonal options), load it with toppings, and the team sets it to harden while you wander the small shop. You leave carrying a cardboard box containing your own decorated chocolate bars. Mine survived a flight home in cabin baggage. Just keep it out of direct sun.
Where to find it and how to get there
The Chocolatarium is at 3-5 Cranston Street, Edinburgh, EH8 8BE. Cranston Street runs north off the Royal Mile, roughly halfway between Edinburgh Castle at one end and Holyroodhouse at the other. If you’ve just done Mary King’s Close, you are about a six-minute walk away.
From Waverley train station it’s a five-minute uphill walk via Market Street and Jeffrey Street. From the castle end of the Royal Mile, expect 10-12 minutes downhill on cobbles. The Hop on Hop off bus drops you at the Royal Mile stop and you walk the last two minutes from there. If you’re already on a city walking circuit and your legs are working, the location is genuinely no effort to add in.
Driving in is a bad idea. Old Town is the part of Edinburgh you want to be on foot for, and parking nearby is expensive and patchy. The closest secure car park is the multi-storey on Blackfriars Street, two minutes away, but I’d park further out (St James Quarter, for example) and bus or walk in.
Picking a tour: which booking is actually best
There is functionally one tour at the Chocolatarium. The 90-minute Tour of Chocolate is the headline product and what nearly every visitor books. So the question isn’t really which tour, but which platform.
You have three choices: book direct on the Chocolatarium’s own site, go through Viator, or go through Klook. Direct booking tends to be marginally cheaper at face value (around £22 for adults, £15 for kids 6-15), but the platform options have a few practical advantages worth thinking through.
1. The Chocolatarium Chocolate Tour Experience: $44
This is the standard tour and what almost everyone should book. Our full review walks through the room-by-room experience and the tasting lineup in detail, including the bits competitors gloss over (the cacao-jungle intro is genuinely informative, not filler). Free cancellation up to 24 hours before makes it the safer pick if your Edinburgh plans are still moving around.
2. The Scotch Whisky Experience Tour and Tasting: $33
If you’re chocolate-curious but also want a properly Scottish second activity in the same afternoon, the Scotch Whisky Experience is the obvious pair. Sensory wise it is the polar opposite of the Chocolatarium: smoke and peat versus cocoa and vanilla. Our full guide to booking the Scotch Whisky Experience compares it head-to-head with the Johnnie Walker venue on Princes Street.
3. Edinburgh Food and Drink Tour with Eat Walk Tours: $164
For a fuller half-day with the Chocolatarium booked separately the morning of, the Edinburgh Food and Drink Tour is the strongest companion. It’s pricier but you get three hours of guided walking, several Scottish food stops, and one whisky tasting baked in. It moves at a proper eating pace.
What it costs and what you get
The Chocolatarium’s gate price is around £22 for adults (16+) and £15 for children aged 6-15. Online platforms list the same product in dollars, currently around $44 per adult on Viator. The roughly six-pound delta versus direct booking covers the platform’s free cancellation window and the convenience of having the booking on the same dashboard as the rest of your Edinburgh plans.
What’s included is generous: the 90-minute tour, the tasting flight (12+ varieties on a normal day), the make-your-own-bar segment, the bar itself, and a guide who actually knows their cacao supply chains. There is no upcharge for any of the above. The shop afterwards is genuinely good but it is a shop, so plan a small extra spend if you want to take Scottish single-origin home.
Group rates and family bookings are easier to handle direct. If you’re booking four or more, message the venue first. They’ll often slot you into a less-busy session and the experience improves when the group is closer to private.
Tour timing: when to book
Tours run 10am to roughly 5pm, every day except Christmas Day and Boxing Day. The first slot is usually 10.30am. Slots after that depend on the day of the week, but expect roughly hourly through the afternoon, with the busiest sessions at 11am, 1pm, and 3pm.
Book at least 48 hours ahead for August (Edinburgh Festival, every slot fills) and for any school holiday. For a normal week in October or February, you can sometimes walk in if a tour has space, but you’d be gambling. The 90-minute structure means each tour is fixed-size, so when it’s full it’s full.
My pick for time of day: aim for an 11am or noon slot. You finish around lunchtime, and you’ll be hungry for proper food after all that chocolate. A late-afternoon tour is fine but you may not feel like a serious dinner straight after.
Allergens, kids, and accessibility
The Chocolatarium is one of the better Edinburgh attractions for allergen awareness. Vegan and vegetarian visitors are catered for as standard: the dark chocolate selection works for most plant-based diets, and the team will swap your tasting plate before the tour starts if you flag it on booking. Nut-free and gluten-free are also handled, but you must email ahead. Cross-contamination is impossible to fully rule out in a working kitchen, so anyone with a severe nut allergy should ask sharp questions before booking.
Kids must be at least 6 years old to join. This is non-negotiable, and the venue is firm about it. The reasoning is partly safety (hot chocolate, demonstration knives) and partly attention span. The 90-minute tour is a stretch for under-sixes. From age 6 onwards it’s a strong family activity. From 8-9 onwards it’s genuinely interesting to them, not just sweet.
Accessibility is the weakest part of the offer. The Chocolatarium is not currently wheelchair accessible. There are entrance steps and a narrow historical doorway. Hearing, visual, and other access needs are catered for if flagged in advance, and there’s a carer discount. If a wheelchair user is in your group and you specifically want a chocolate experience, contact the venue first and they’ll give you a straight yes or no. Don’t book on hope.
Pairing it with the rest of your Edinburgh day
Ninety minutes is a small chunk of an Edinburgh day, so the real planning question is what you put around it. The geography helps: you’re a short walk from Edinburgh Castle, Mary King’s Close, and the entrance to the South Bridge Vaults, all on or near the Royal Mile.
The combo I’d recommend most: morning Chocolatarium slot, lunch on Cockburn Street, afternoon at the Scotch Whisky Experience. You start sweet, you end smoky, you’ve covered both of Edinburgh’s two flagship sensory attractions in one walking-distance loop. If you’ve only got one day in the city this is a good spine.
For families with older kids, swap the whisky for the Harry Potter Walking Tour. Greyfriars Kirkyard is a six-minute walk south, and the tour visits the graves Rowling drew names from. Chocolate plus Tom Riddell’s tombstone is an unbeatable Edinburgh combo for anyone aged 9-14.
If you’re over multiple days and want to add a Scotland-Highlands element later, the whisky tasting guide covers the day-trip options out of Edinburgh too.
The chocolate itself: what you’ll actually taste
The tasting flight changes a little with what’s in season and what’s been produced that week, but the spine is consistent. You’ll get a Madagascan single-origin (bright, slightly fruity), a Venezuelan dark (deeper, more leather and spice), an Ecuadorian 80% (the bitter one, with a real hit at the back of the tongue), and a milk chocolate to reset your palate. Then you’ll move into Scottish-made bars, and probably a chilli bar or a sea-salt one to finish.
White chocolate gets defended properly here. The guide will explain why most people think they don’t like it (most supermarket white chocolate is sugar with cocoa butter and not much else) and then hand you a piece that’s actually well-made. I came in dismissive and left convinced. Talia, one of the regulars in the visitor reviews, called white chocolate “the real deal” after her tour. Same direction.
Dark chocolate fans get the most out of the Madagascan and Venezuelan single origins. They are the kind of bars you nibble rather than chew, and the Chocolatarium will hand you a small printed card with tasting notes if you ask. The cards are useful at home for working out what to order online afterwards.
The make-your-own bar segment
The make-your-own segment is the part kids will not stop talking about, and frankly the part most adults love too. You’re given a mould (Edinburgh Castle, thistle, simple bar shape, a couple of seasonal ones), a ladle of tempered chocolate, and a counter loaded with toppings.
The toppings are the bottleneck. Dried raspberries, candied orange peel, honeycomb, salted pretzel pieces, mint, chilli, marshmallow, and a few I’d never heard of. People take longer than they think to choose. The trick is to commit to one or two flavour ideas before you start (I went with raspberry-and-sea-salt, plus a honeycomb-only as a control). You’ll regret a kitchen-sink bar later.
Once decorated, your bar goes onto a tray to harden while you finish the tour. You collect it on the way out, in a cardboard box with the Chocolatarium logo. Survives a flight home. Doesn’t survive a sunny picnic.
How it stacks up against the wider Edinburgh food scene
Edinburgh has a strong food and drink tour scene and the Chocolatarium fits as a niche slot rather than a flagship. The flagship sensory tour in town is still the Scotch Whisky Experience. The flagship walking food tour is the Eat Walk three-hour. The Chocolatarium is the third major option, and the only one that’s chocolate-led.
Which to book if you only book one? My take: if you’re a chocolate person and you’ve never been hands-on, do the Chocolatarium. If you’re more interested in a broad sweep of Scottish food, do Eat Walk. If you want to taste the country in a single 75-minute hit and don’t mind it being whisky, do the Scotch Whisky Experience. Don’t try to do all three on the same day. Two is the sensible cap. The food and drink walking tour cousin in London is on a different rhythm but the same logic applies: spread food tours across days.
What competitors are quiet on but is genuinely true: the tour is a low-effort half-morning. Ninety minutes, a short walk, no queue if you’ve booked, no real fitness requirement. For visitors recovering from a Castle climb or a long museum day, it’s about the easiest cultural-adjacent activity in Old Town. I’d put it on a soft day rather than a marathon walking day. You’ll appreciate the chocolate more if you’re not already exhausted.
A short history of why Edinburgh is good at this
Scotland isn’t a chocolate-producing country and never has been. No cacao tree has ever survived a Scottish winter. So why does Edinburgh have a serious artisan chocolate scene at all?
The short answer is that Britain has been a chocolate-importing country since the 17th century. Cocoa houses opened in London in the 1650s. By the 19th century Cadbury, Rowntree, and Fry were building the British mass-chocolate industry, mostly in Birmingham, York, and Bristol. Scotland followed the same trajectory at smaller scale, with Tunnock’s near Glasgow becoming the household name (the caramel wafer is older than most modern Scottish brands).
The artisan wave is much more recent. From around 2010 onwards, small bean-to-bar makers started opening across the UK, often as one-person operations buying single-origin beans direct from cacao farms and finishing the chocolate themselves. The Chocolatarium is part of that wave. Founded in Edinburgh, it sits at the visitor-facing end of a UK-wide bean-to-bar movement.
What the tour does well, and competitors don’t: it explains how that supply chain works. You walk out understanding why a £6 single-origin bar is fairly priced and a £1.50 supermarket bar is not. Not in a preachy way. Just clearly. That alone is worth the ticket if you’ve ever wondered what the difference actually is.
Booking platform comparison: Viator versus Klook versus direct
Three sensible ways to book.
Direct on chocolatarium.co.uk: cheapest face-value price (£22 adult, £15 child). Best if you’re certain of your dates and not booking other Edinburgh activities through a platform. Cancellation terms are slightly tighter than Viator.
Viator: priced in dollars, currently around $44. Free cancellation 24 hours before. Useful if your other Edinburgh bookings are on Viator already (the Underground Vaults and several castle tours are on the same platform), so everything sits on one dashboard. This is what I usually recommend.
Klook: similar pricing to Viator, sometimes a small Klook-only discount if you’ve used the platform before. Worth a price-check if you have a Klook account and credits to burn. Less common for Edinburgh than Viator but the inventory is real and the cancellation terms are reasonable.
Whichever you pick, book ahead in summer. August (Festival month) is genuinely full. Other months you’ve got more flexibility but the popular slots (11am, 1pm, 3pm) still fill 24-48 hours out.
Quick FAQ
How long is the actual tour? 90 minutes. Plan 1 hour 45 minutes total to allow time in the shop afterwards.
Is it worth it for adults without kids? Yes. The tasting and history segments are pitched at adults first. Kids enjoy the make-your-own bar, but adults often enjoy the rest more.
Can I do this and Edinburgh Castle in one day? Yes, easily. They are 10 minutes apart. Castle in the morning (allow 2-3 hours), Chocolatarium at 1pm or 2pm.
Is there a separate paid kids’ workshop? No. The standard tour includes the make-your-own segment for everyone. Children pay £15 and get the same hands-on slot as adults.
Do they sell out? Yes, especially August and during school holidays. Book at least 48 hours ahead in those windows. In quieter months you can sometimes walk in.
Can I refuse the chocolate? Is there a vegan option? Vegan, vegetarian, and lactose-free pathways are standard. Flag on booking. The dark chocolate selection is naturally vegan.
More Edinburgh and food-and-drink reading
For the rest of your Edinburgh planning, the Scotch Whisky Experience guide is the obvious next read if you want a full afternoon-of-flavour itinerary. Edinburgh Castle is the morning anchor for almost any Old Town day, and the Hop on Hop off is the easiest way to link the city’s bigger sights without burning your legs out before the chocolate kicks in. For a totally different food-and-drink walking experience, the London historic pub walking tour is the closest English-side cousin in pace and pricing.
