The Journey to the Similan Islands: What to Expect from Start to Finish

Pickup & Transfer

The adventure begins with a hotel pickup from Phuket, covering three drop-off points in the Thalang District, Chalong, or central Phuket. Expect around a 2-hour van ride to the Thap Lamu Pier, a straightforward way to start your day without worrying about logistics. This transfer is crucial because it ensures you’re at the private pier on time, ready for the boat cruise. The early start might cut into your sleep-in plans but offers a peaceful, scenic ride through the Thai countryside.

Welcome at Thap Lamu Pier

Once you arrive, you’ll be greeted with refreshments—either tea, coffee, or juice—before heading to the boat. This laid-back start sets the tone and gives you a chance to gear up for the day. It’s worth arriving in comfortable clothing that can get wet and packing a light jacket just in case the breeze is brisk.

The Catamaran Experience

The catamaran cruise itself lasts approximately 1.5 hours, during which you can settle into your seat, admire the sea views, or chat with fellow travelers. The vessel is described as a luxury speed boat, though one review notes that it can carry around 60 guests, which might make it feel somewhat crowded at times. It’s equipped with space for snacks and drinks, which are served throughout the day, helping to stave off any hunger or thirst.
