At 314 meters, the King Power Mahanakhon Tower held the title of Thailand’s tallest building for six years before losing it in 2024. But the Skywalk on its rooftop? That’s still the highest outdoor observation deck in the country, and the Glass Tray floor at 310 meters up remains one of the most nerve-testing tourist attractions in all of Southeast Asia.


The building itself is impossible to miss. That pixelated, spiraling cutout design along the facade looks like someone took a bite out of a skyscraper. It was designed by Ole Scheeren (the same architect behind Beijing’s CCTV Tower) and opened in 2016. The Skywalk attraction occupies the 74th, 75th, and 78th floors, with a rooftop bar on 76.

What makes Mahanakhon different from other observation decks I’ve been to is the open-air rooftop. Most skywalk experiences keep you behind glass. Here, you step outside on the 78th floor with nothing but a waist-height railing between you and the Bangkok skyline. The wind hits you, the noise of the city drifts up, and the sense of height feels real in a way that indoor observation decks never quite manage.

Short on time? Here are my top picks:
Best for the Skywalk alone: Mahanakhon SkyWalk Entry Ticket — $42. Standard admission with indoor and outdoor deck access plus the Glass Tray. Book online for guaranteed entry and shorter queues.
Best combo deal: Damnoen Saduak, Train Market & Mahanakhon Day Trip — $23. Full day combining two iconic markets with the Skywalk — absurd value for what you get.

How Tickets and Entry Work

Mahanakhon SkyWalk tickets are straightforward, but the pricing varies depending on where and how you buy them.
n

Standard admission covers the indoor observation deck (74th-75th floors), the outdoor rooftop (78th floor), and the Glass Tray experience. Walk-up prices at the building start at 880 THB (about $25) for adults and 250 THB for children aged 3-12. Under 3 is free. But here’s the catch — walk-up availability isn’t guaranteed, especially during sunset hours when everyone wants to be up there.
Online booking is where it gets interesting. Prices through platforms like GetYourGuide and Klook are often lower than walk-up rates, sometimes significantly so. The GYG ticket I’m recommending comes in at about $42 and includes guaranteed entry — no waiting, no sold-out worries. During peak season (November through February), walk-up visitors regularly get turned away at sunset.
Ticket types to know about:
- Standard admission: Indoor + outdoor decks + Glass Tray. This is what most people need.
- Rooftop bar package: Some booking platforms offer a ticket that includes a drink at the SkyBar on the 76th floor. It’s a nice addition if you’re visiting at sunset and want to linger.
- Fast Track: Available for about 1,500 THB ($43) — skips the elevator queue. Honestly unnecessary on most days, but worth it on weekend evenings when the wait can stretch to 20-30 minutes.
The ticket office is on the ground floor of King Power Mahanakhon in the shopping mall section. You’ll go through a brief bag check before taking the high-speed elevator to the 74th floor. The elevator ride itself is an experience — the walls are screens showing a light show as you rocket up in about 50 seconds.
Online Tickets vs. Walk-Up: Which Is Better?

Online wins this one by a comfortable margin. Here’s the breakdown.
Buy online if:
-
n
- You want to visit during sunset (roughly 5:00-6:30 PM depending on season) — this is peak demand and sells out
- You want a lower price — online platforms consistently undercut walk-up rates by 15-30%
- You’re visiting on a weekend or during Thai holidays
- You want the combo with a drink or with a market tour

Walk-up is fine if:
- You’re visiting on a quiet weekday morning
- You don’t care about seeing the sunset from up there
- You’re already in the King Power Mahanakhon mall shopping and decide to go on a whim
One thing worth knowing: the Mahanakhon building is part of the King Power duty-free empire. The ground floors are a massive duty-free shopping complex. If you’re flying out of Bangkok soon, you can combine a Skywalk visit with duty-free shopping — just bring your passport and boarding pass.
The Best Ways to Book Mahanakhon Skywalk
There are really only two tours worth looking at here — the standalone ticket and the day-trip combo. The Skywalk isn’t the kind of attraction that needs a guided tour or lengthy explanation. You go up, you look around, you step on the glass floor (or don’t), you come back down. What matters is getting the right ticket at the right price.
1. Mahanakhon SkyWalk Entry Ticket with Options — $42

This is the standard entry ticket and the one most people should book. You get access to all three observation levels — the indoor deck with its interactive displays on the 74th and 75th floors, the open-air rooftop on the 78th floor, and the Glass Tray. Some ticket options on GYG include a drink at the rooftop bar, which is worth the small surcharge if you’re planning to stay for sunset.
At $42, it’s competitive with what you’d pay at the door, and the confirmed booking means you won’t get turned away. Over 4,000 people have booked through this listing with a 4.6-star rating. The main complaints are from people who visited on cloudy days — the view is obviously weather-dependent, so check the forecast before you commit to a specific date.
The Glass Tray itself is a clear glass panel on the 78th floor that you walk (or crawl) across. It holds up to 14 people at a time, and yes, it’s safe. But your legs might disagree with your brain on that point.
2. Damnoen Saduak, Train Market & Mahanakhon Day Trip — $23

This one is genuinely hard to believe on price. $23 gets you a full-day guided tour starting with Damnoen Saduak Floating Market (the famous one with boats loaded with fruit and noodles), then the Maeklong Railway Market where vendors fold their stalls as the train passes through, and finishing with Mahanakhon SkyWalk in the late afternoon. Transport, guide, and all entry fees are included.
If you haven’t already done the floating market and train market tour, this combo makes the Skywalk essentially free — the market tours alone cost more than $23 from most operators. The timing works well too: markets in the morning when they’re liveliest, Skywalk in the late afternoon when the light is best.
The trade-off is less flexibility on timing — you arrive at Mahanakhon when the tour gets there, not when you choose. With 2,162 reviews and a 4.7-star rating, this is actually the better-reviewed of the two options.
When to Visit (Timing Is Everything Here)

n

The Mahanakhon SkyWalk is open daily from 10:00 AM to midnight, with last entry at 11:00 PM. That’s a wider window than most observation decks, and the late closing means nighttime visits are a real option.
Best time: 4:30-5:30 PM arrival. This lets you see the city in daylight, watch the sunset from the rooftop, and then stay for the lights coming on as Bangkok shifts into its night mode. You get three different views in one visit. The trick is arriving about 45 minutes before sunset — start with the indoor floors, work your way up, and time the rooftop for when the sky turns gold.
Second best: 8:00-9:00 PM. Smaller crowds, the city is fully lit, and the temperature has dropped from the daytime heat. You miss the sunset transition but gain a more relaxed experience with shorter waits for the Glass Tray. If you go this route, a tuk-tuk night tour afterward makes for a solid evening — you’re already in the Silom area and the tours run late.
Skip: 11:00 AM to 2:00 PM. Harsh overhead light, heat haze kills the long-distance views, and it’s the busiest window for tour groups. The midday sun also makes the Glass Tray experience less dramatic — the transparent floor is more impressive when you can see city lights below rather than washed-out rooftops.
Weather note: Bangkok’s skies are clearest from November through February. During the rainy season (June-October), afternoon thunderstorms can roll in fast. Morning visits are safer in wet season, but check the radar before heading up — the view from inside an observation deck during a downpour is not worth the ticket price.
How to Get to Mahanakhon SkyWalk
n


This is one of the easiest major attractions to reach in Bangkok. The King Power Mahanakhon Tower is directly connected to the BTS Skytrain system.
By BTS (recommended): Take the Silom Line to Chong Nonsi Station. Use Exit 3 — it connects directly to the building via a covered skywalk. Door to door from Siam Station takes about 8 minutes. From Asok (Sukhumvit area), transfer at Siam and the total ride is about 15 minutes. A single BTS trip costs 16-59 THB depending on distance.
n

By Grab/taxi: Grab costs about 80-200 THB from central Bangkok, depending on traffic and distance. The building is at 114 Narathiwas Ratchanakharin Road in the Silom/Sathorn district. Tell the driver “King Power Mahanakhon” — every taxi driver in Bangkok knows it. Be aware that the Silom/Sathorn area has some of the worst traffic in Bangkok during rush hour (5:00-7:30 PM), which is exactly when most people want to arrive for sunset. The BTS avoids this entirely.

From Khao San Road: No direct BTS connection. Take a taxi or Grab (about 100-180 THB, 20-40 minutes depending on traffic) or boat to Sathorn Pier and walk 10 minutes.
From Suvarnabhumi Airport: Airport Rail Link to Phaya Thai, BTS to Siam, transfer to Silom Line, exit at Chong Nonsi. Total journey: about 60-75 minutes, 90 THB. Or take the express train to Makkasan and transfer to MRT, but the BTS route is simpler.
If you’re spending the day sightseeing rather than heading straight to Mahanakhon, the hop-on hop-off bus and river boat pass covers most of the major landmarks and drops you near Chong Nonsi for the Skywalk at the end of the day.
Tips for Getting the Most Out of Your Visit

n

- No food or drinks on the Glass Tray. They’ll make you leave bags and bottles at the edge. Phones are allowed but you’ll be asked to use the wrist strap or lanyard — they’re serious about this.
- Wear shoes with grip. The Glass Tray and outdoor rooftop can be slippery, especially when humid. Heels and flip-flops technically aren’t banned, but you’ll regret both.
- Free photos at entry. There’s a green-screen photo station when you first arrive. The photos are free to take — you can buy printed or digital versions afterward for about 200-500 THB. Honestly, your own phone photos from the top will be better.
- Budget 60-90 minutes. Most people spend about an hour total. Rushing through in 20 minutes means you’ll miss the interactive exhibits on 74-75 and probably regret not spending more time on the rooftop. If you finish earlier than expected, a Bangkok food tour is an easy follow-up — several of them start in the Silom-Sathorn area within walking distance of the tower.
- Go twice if you can. Once at sunset, once late at night. The two experiences are completely different. If you’re staying in Bangkok for a few days, the cost is worth it.
- The rooftop bar is separate. You can access the SkyBar on the 76th floor without a Skywalk ticket — it’s a restaurant and bar with its own entrance. Minimum spend of about 1,000-1,500 THB applies. Nice cocktails, though the view is technically worse than the observation deck one floor up because of the restaurant walls.
What You’ll Actually See from the Top
n


The 360-degree view covers essentially the entire Bangkok metropolitan area. On a clear day, the visibility extends 50-60 kilometers in every direction.
Looking north: The Chao Phraya River winds through the city, with Wat Arun and the Grand Palace visible along its banks. The cluster of skyscrapers around Ratchaprasong and Siam is the commercial heart of Bangkok. Beyond that, you can see Don Mueang Airport on very clear days.
Looking east: The Sukhumvit corridor stretches to the horizon — an unbroken line of high-rises, malls, and condos. You can pick out the distinctive Baiyoke Tower II (Bangkok’s former tallest building) and the bulk of Terminal 21 mall.
Looking south: Lumpini Park appears as a surprising rectangle of green in the concrete sprawl. Beyond it, Suvarnabhumi Airport is visible as a flat expanse with the occasional glint of an arriving aircraft. The Gulf of Thailand is technically visible on the clearest days, though most visitors can’t quite distinguish it from the haze.
n

Looking west: The Thonburi side of the river is lower-rise and greener, with more temple spires than skyscrapers. It’s the most visually interesting direction at sunset because the light hits the temples and the river at the same time.

The Glass Tray floor is on the outdoor section of the 78th floor. It’s a clear glass panel about 4 meters wide that juts out from the building’s edge, with a direct view down to the street 310 meters below. The glass is rated for extreme loads — it’s perfectly safe, and the staff will remind you of that while you stand there trying to convince your knees to stop shaking. Up to 14 people can be on it at once, and during busy periods the staff cycle groups through every few minutes.
If you’re genuinely afraid of heights, you can still enjoy 90% of the experience without stepping on the glass. The views from the solid-floor sections of the rooftop are identical — the Glass Tray is more of a thrill ride than a viewing improvement.

What to Pair with the Skywalk
n


The best evening after Mahanakhon is a Chao Phraya dinner cruise — you spend the afternoon staring down at the river from 78 floors up, then spend the evening floating on it while the skyline you just stood on top of glows behind you. The canal tours by longtail boat work well as a morning-before-Skywalk plan, since they run through the older neighborhoods west of the river where life looks nothing like the glass-and-steel corridor around Mahanakhon. If you want to cover ground at street level first, the Bangkok bike tours loop through backstreets and temples that you can later spot from the rooftop — it gives the aerial view more meaning when you recognize what you’re looking at. For a full-day contrast, the Ayutthaya day trip swaps modern Bangkok for 14th-century ruins about 80 kilometers north, and most tours get you back in time for a sunset Skywalk session. And if you’re still in the city after dark with energy to spare, Muay Thai at Lumpini Stadium is a 10-minute walk from Mahanakhon — you can literally see the stadium from the observation deck.
