All the details about your upcoming adventure in one place
The Similan Islands, a group of nine granite islands in the Andaman Sea, offer some of the best snorkeling and diving in the world. Accessible only from mid-October to mid-May, this protected marine park is renowned for its crystal-clear azure waters, thriving coral reefs, and the famous 'Donald Duck Bay' with its balancing Sail Rock. A day trip from Khao Lak is the most convenient way to visit, with a short 75-90 minute speedboat ride transporting you to this tropical paradise where you can swim with sea turtles and relax on powdery white beaches.

Real experiences from real travelers
We booked the Wow Andaman tour and it was incredible. The snorkeling at Island 9 was like swimming in an aquarium. The crew was so attentive and the lunch was surprisingly good. Highly recommend!
The islands are stunning, exactly like the pictures. The speedboat ride from Khao Lak was fast (about 1h 15m). It gets busy at Donald Duck Bay, but the guides managed it well. Saw a sea turtle!
Went with SeaStar Andaman. Very organized, good equipment, and they took great care of my elderly mother. The water clarity is unmatched.
We chose the luxury catamaran option to avoid the bumpy speedboat ride. It was so much smoother and more relaxing. Worth the extra money for the comfort.
Remember no fins allowed on the beach! The rangers are strict but it keeps the sand clean. Snorkeling stops were fantastic, lots of Nemo fish.
Booking was easy and the pickup from our Khao Lak hotel was on time. The view from Sailing Rock is a must-do. Bring lots of sunscreen!
The tour operator provided a great Halal lunch box upon request. The crew was very respectful and the islands are breathtaking.
It's a full day trip. 8am pickup, back by 5pm. The boat ride can be choppy, so take sea sickness tablets if you're prone. The water color makes it all worth it.
Everything you need to know for your journey
The best time is between December and March when the sea is calmest and visibility is highest. The park is strictly open only from October 15 to May 15.
The speedboat journey from Thap Lamu Pier in Khao Lak takes approximately 75 to 90 minutes depending on sea conditions.
Most tour prices include the National Park fee (approx. 500 THB), but always check the specific 'What's Included' section of your booking. If not, you may need to pay cash at the pier.
Generally, no. Overnight stays in bungalows are currently restricted or closed to the general public to preserve the ecosystem. Only authorized liveaboard boats are permitted for multi-day trips.
Yes, there are basic toilet and shower facilities on Island No. 4 (Koh Miang) and Island No. 8 (Koh Similan), but they are simple national park facilities.
Yes, mask, snorkel, and life jackets are standard inclusions on all tours. Fins are sometimes included for snorkeling stops but are often prohibited on the beach itself to protect the sand.
No, the National Park has a 'no shoes on beach' policy to protect the white sand. You will typically leave your flip-flops at the pier or on the boat before stepping onto the sand.
It is suitable for active children, but not recommended for infants under 1 year or toddlers who cannot sit still for 1.5 hours on a speedboat. The ride can be bumpy.
No, full-day tours include a light breakfast at the pier, a buffet or box lunch on the island, and snacks/drinks throughout the day. Vegetarian and Halal options are usually available upon request.
