About this tour
When Alex from our team took this snorkeling tour out of Koh Yao Noi, we headed straight for Hong Island — genuinely one of Thailand's standout reef spots. The five-hour run hits the lagoon, the island's viewpoint, and a string of smaller islands nearby, with a private boat and packed lunch thrown in. The Andaman coast around here is warm, fairly quiet compared to Phuket, and draws a mix of backpackers and small groups. Needs at least two people to go ahead, so worth coordinating if you're solo.
Highlights
- Hong Lagoon's turquoise water and enclosed limestone walls are photogenic as hell
- Snorkeling straight off the boat — no trudging through resort beaches
- Viewpoint hike gives context to the island layout and karst geology
- Lunch box and fresh fruit between dives kept energy up properly
- Private boat meant flexibility to linger at good reef patches
- Water clarity and coral health better than many mainland Andaman spots
- Koh Yao Noi basecamp is low-key, fewer day-trippers than busy islands
What to expect
You'll meet at your accommodation on Koh Yao Noi or Koh Yao Yai early — exact time depends on tides and boat logistics. The boat ride to Hong takes roughly 45 minutes depending on conditions; Alex found the open water pleasant and the crew competent with gear. Once there, you'll do two main snorkel sessions with a break for the viewpoint trek (a short, steep scramble, not technical but hot). The reef itself has decent hard coral, schools of reef fish, and occasionally larger visitors like rays or small sharks.
Lunch happens onboard or at a sheltered anchorage — expect a solid packed meal, not fancy but filling. The pace is relaxed; your crew isn't rushing you between spots. Afternoon light on the lagoon is particularly sharp. By mid-afternoon, you're heading back. No overnight stays, so you're back before sunset. The real rhythm depends on boat traffic and how much time you want in the water.

Good to know
Private boat setup beats crowded speedboat tours — your guide isn't managing 40 bodies. The included snorkel kit is fine for casual divers, and the reef health here outpaces some of the thrashed areas closer to Phuket. Best for confident swimmers who don't panic in open water; the lagoon is sheltered, but the outer reefs are genuine sea conditions.
Early start and full-day water time will knacker you if you're unfit or recovering from anything. The viewpoint hike is steep and rope-assisted in patches — doable for most, rough if you have knee or spine issues. It's genuinely not recommended for pregnant travellers, anyone with cardiac concerns, or spinal injuries. Infants have to sit on a lap in the boat (no safety restraints); dodgy in rough seas. Two-person minimum means last-minute cancellations are possible if your booking partner flakes.
Wear reef-safe sunscreen (zinc oxide). Bring a rash guard if your skin is sensitive. Morning tends calmer for water conditions; check wind forecasts. Private transport is arranged, but public minibuses also run from the pier if you're tight on budget. Trip sits at five hours all-up, so expect to be wet and salty by dinner.
