About this tour
When Jake from our team booked this snorkeling run from Khao Lak to the Similan Islands, we got a proper day out on the Andaman Sea. The Simlian Islands are a cluster of granite-studded, jungle-clad national parks strung along Phang-Nga's west coast—about 90 minutes by speedboat from Thap Lamu Pier. The underwater visibility runs deep (30m on good days), coral gardens are genuinely lush, and if you're lucky, dolphins and sea turtles show up. The tour swings you past Sailing Rock for the postcard view, gets you snorkeling at a couple of spots, feeds you Thai food and fresh fruit, and bundles in transfers from your hotel. It's an 8–9 hour day suited to swimmers and keen snorkelers who don't mind early starts and boat time.
Highlights
- Granite boulder islands with turquoise bays and white sand beaches
- 30-metre visibility underwater—corals and tropical fish are genuinely pristine
- Sailing Rock formation delivers sweeping views across the island cluster
- Dolphins and sea turtles spotted regularly; not guaranteed but plausible
- Thai traditional lunch included mid-tour, plus fresh fruit and drinks
- Snorkel gear (mask, fins, life-jacket) and English-speaking guide provided
- Hotel pickup and drop-off saves faffing with transport logistics
- Speedboat ride itself is part of the appeal—fast, wet, scenic
What to expect
You'll start early with breakfast at the pier (included), then speed out to the islands in about 90 minutes. The boat hits two or three snorkel sites depending on conditions and crowd levels. Water temperature is warm year-round, and visibility is usually excellent—you're looking at coral formations, schools of reef fish, and the odd turtle or ray gliding past. Sailing Rock is a natural stop for photos; it's a stunning formation that rises from the sea and gives you a sense of the islands' scale. Lunch is Thai traditional fare served on the boat or at an island beach. Between snorkels there's time to rest, dry off, and chat with other guests. The return trip takes another 90 minutes, so factor in full-day pacing. Jake's team found the pacing relaxed rather than rushed—you're not cramming a dozen stops into the day, so each snorkel slot feels unhurried.

Good to know
Similan Islands genuinely rank among South-East Asia's top snorkel destinations. Visibility is typically excellent, wildlife encounters are common enough to be realistic, and the granite-and-jungle scenery is striking. Suits confident swimmers, beginners with snorkel experience, and anyone keen on warm-water reef exploration. Gear is provided, so you don't need your own. A whole day out beats a rushed half-day jaunt.
National park entry fees (400 THB adults, 200 THB kids) aren't included—budget separately. You'll need to surrender your passport after booking so the operator can pre-register you; it's standard procedure here but feels clunky. The tour isn't suitable if you have spinal injuries, heart conditions, high blood pressure, bone disease, or pregnancy. Early starts (typically 6–7am hotel pickups) are the norm. Seasickness can strike on the speedboat ride, especially in rough swells; take tablets if prone. Group sizes are often 20–40 people, so it's not intimate. Bring sunscreen (reapply often), a rash guard or shirt for UV protection, and a waterproof bag for valuables—the boat has limited secure storage.
