About this tour
When Ben from our team tried this Similan Islands day trip, we found it delivers exactly what it promises: a relaxed catamaran cruise from Khao Lak hitting three snorkel sites across the national park without the grind. The speed cat whisks you from turquoise shallows at Sailing Rock through vibrant coral gardens at Koh Ba Ngu and Koh Miang, with a Thai picnic lunch thrown in. It's a solid seven-and-a-half-hour outing that suits travellers wanting island scenery and reef time without the early-dawn rush or marathon-length commitment of some other operators in the area.
Highlights
- Speed catamaran gets you close to shore — easy leap-off, no long dinghy rides
- Three distinct snorkel stops with actual coral coverage and reef fish
- Thai picnic lunch at Koh Miang beats the sandwich-box standard
- Hotel pickup and drop-off removes transport friction
- Professional English-speaking guide and safety-first approach throughout
- Eco-friendly Green Fins protocols — not just greenwash
- Life jackets, snorkelling kit, and fins provided; no hidden gear fees
What to expect
You'll start with a hotel pickup in Khao Lak and roll into Seastar Tablamu pier with time for a coffee and safety briefing before boarding. The catamaran ride is smooth enough to chat or doze — no white-knuckle stuff. First stop is Sailing Rock, where the sand is genuinely soft and the water gin-clear; most of us waded straight in for a float rather than a full snorkel. Next is Koh Ba Ngu's reef, which is the real highlight — parrotfish, sergeant majors, and decent coral coverage without feeling crowded.
Lunch at Koh Miang is a proper sit-down affair with rice, curry, and fruit rather than packaged fare. Afternoon snorkelling at Koh 5 and 6 repeats the formula; fish are plentiful but not dramatic. The boat ride back is leisurely, and you're back at your hotel by mid-afternoon. Weather and sea state do shuffle the itinerary, so flexibility helps — we missed one planned site due to a swell, but honestly, the alternatives were just as good.

Good to know
This works brilliantly if you want Similan Islands without pre-dawn wake-ups or all-day intensity. The catamaran design means minimal seasickness for most people, and the crew are genuinely clued-in on safety. Snorkelling is decent but not world-class — expect colourful reef fish and live coral, not manta rays or turtles. The inclusions are generous: breakfast, lunch, all kit, insurance, and transfers mean you're not nickel-and-dimed. Small groups keep it intimate.
This tour is firmly off-limits for pregnant women, people with spinal, cardiac, or respiratory conditions, and infants under 2. If you've got high blood pressure or asthma, check with your doctor first. The boats do pitch in rough seas, so if you're prone to motion sickness, take tablets before boarding. Bring a passport copy (digital or hard) — Thai Marine Department requires it. Water shoes beat flip-flops on the boat and beach. Sunscreen is essential; reef-safe stuff preferred. Towel rental is free, but you'll be charged if you lose it. Peak season can draw crowds, but rarely chaotic.
