What Travellers Say
Reviews Summary
Visitors consistently praise the Similan Islands for their breathtaking natural beauty, describing the waters as crystal-clear turquoise and the beaches as powdery white. The vibrant marine life makes it a diver's and snorkeler's paradise. However, some find day trips to be crowded and the travel time quite long.
"Beautiful & amazing islands 💞 Really worth to come eventho the journey is quite far from the mainland Phang Nga, takes up to 1 hour & 30 minutes by catamaran boat. Clean & white beaches. A must go for a short hike to the viewpoint. Clear & nice trail. Hope the corals will grow even more & preserved well. Keep protecting this national park ❤️"

"Visiting Similan Islands National Park was an unforgettable experience. The natural beauty is absolutely breathtaking—crystal-clear turquoise waters, powdery white sand beaches, and vibrant marine life that makes it a diver’s dream. Whether you’re snorkeling, diving, or just relaxing on the beach, every moment feels magical. The underwater visibility is incredible, and I was lucky to see colorful coral reefs, sea turtles, and schools of tropical fish. It’s also well-preserved, with a focus on conservation, which I really appreciated. A must-visit for nature lovers and adventure seekers"
Thabang Lekwadi
"The islands are quite far from Karon Beach. It takes about an hour and a half by bus to the pier (near the bridge connecting Phuket to the mainland), then an hour and 40 minutes by speedboat to the islands. Each island stop is about 30 minutes, so you get three 30-minute sessions to swim and take photos, plus an hour on the last island. The return trip takes the same amount of time to get back to the hotel. Overall, the travel time is very long, which is a big downside. The service is good, and the islands are amazing. As for the price: you should negotiate, it usually comes out to about 2000 baht per person.
The food is simple – snacks, rice, chicken, no alcohol, but they provide water. Suggest you read other feedback."

For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids
Tips for families: Pack plenty of sunscreen, hats, and rash guards for everyone. Consider bringing some familiar snacks if your children are picky eaters, though tours usually provide adequate food. Focus on the snorkeling and beach time, as the limited time on each island means you won't be able to explore extensively. The sheer beauty of the islands is often captivating for kids, offering a memorable introduction to Thailand's natural wonders.
🐠 Diving Enthusiasts
+1While day trips offer snorkeling and introductory dives, a liveaboard experience is highly recommended to fully appreciate the Similans' diving potential. Liveaboards allow access to more remote sites and multiple dives per day, often during optimal conditions. This is the best way to explore the vibrant coral gardens, swim-throughs, and encounter the rich marine biodiversity that makes the Similans a diver's paradise.
📸 Photography Buffs
+1For underwater photography, the exceptional clarity of the water and the abundance of colorful marine life present endless opportunities. Consider bringing a waterproof camera or housing for your gear, as you'll likely get splashed on the speedboat. Early morning or late afternoon light can offer softer, more flattering conditions for landscape shots, though access to specific viewpoints might be limited by tour schedules.

In-depth insights and expert knowledge
The Similan Islands: A Protected Marine Paradise
+1Visitors can explore a select few of these islands, typically Islands #4 and #8, which offer the most accessible and iconic experiences. Island #8, often called Sail Rock, is famous for its distinctive rock formation that provides a panoramic viewpoint. Island #4 boasts some of the most beautiful beaches, with powdery white sand and incredibly clear turquoise waters. The park's commitment to preservation means that the scenery and underwater world remain remarkably pristine, offering an almost untouched tropical paradise experience.
+1The park's closure from May to October is crucial for the rejuvenation of its marine life and to protect it from the monsoon season's rough seas. This seasonal opening ensures that the natural beauty that draws visitors from around the globe is maintained for future generations. Planning your visit within the open season is key to experiencing this underwater and above-water wonderland.
Diving and Snorkeling Adventures
+1For divers, sites like Koh Bon (part of the Similan Islands National Park) are particularly famous for manta ray sightings, especially at their 'cleaning stations'. Liveaboard trips are highly recommended for serious divers, as they allow for multiple dives at prime locations, often during less crowded times. Day trips also offer fantastic snorkeling opportunities, with many tours providing gear and guided excursions to prime reef spots.
+1When snorkeling or diving, it's imperative to practice responsible tourism. Avoid touching or standing on corals, as they are fragile living organisms. Do not feed the fish, as this disrupts their natural feeding habits. By respecting these guidelines, visitors contribute to the ongoing preservation of this incredible marine environment.
Navigating Day Trips vs. Liveaboards
Liveaboard diving trips, on the other hand, provide a more in-depth experience. These multi-day excursions allow you to explore more dive sites, often at dawn and dusk when marine life is most active and crowds are minimal. Liveaboards cater primarily to divers but offer an unparalleled way to experience the Similans' underwater wonders and wake up to breathtaking island views.
Regardless of your choice, be prepared for the travel time involved. Day trips require an early start and a late return, making it a full-day commitment. Liveaboards, while requiring more time, eliminate the daily travel hassle and maximize your time exploring the islands and their surrounding waters.
