About this tour
When Sarah from our BugBitten team took this longtail boat snorkel trip to the Koh Hong islands in Krabi, we found ourselves in genuinely spectacular waters. Four pristine islands wrapped in limestone cliffs, part of the National Marine Park and framed by Phang Nga Bay's dramatic rock formations—you're looking at arguably the most striking scenery in the province. The nine-hour outing departs from Ao Nang and splits time between cruising the longtail, snorkelling at multiple reef sites, and a midday lunch break on one of the islands. It's a proper day on the water with a small group, English-speaking guide included, and all the gear sorted.
Highlights
- Longtail boat journey—slower than speedboat, better for absorbing the limestone backdrop
- Four islands with distinct reef patches and marine life variety
- Lunch included on-island, plus seasonal fruit and water throughout
- Phang Nga Bay scenery rivals anything else in Krabi
- Snorkel gear, life jacket, and sea guide all provided
- Nine-hour itinerary gives proper time underwater, not rushed
- English-speaking guide navigates tide times and best spots
What to expect
The day starts with a pickup and transfer to Ao Nang, where you'll board a traditional wooden longtail boat. Unlike faster speedboats, the 45-minute ride to Koh Hong lets you soak in the scenery—limestone pinnacles rising from the sea, the water shifting from jade to deep blue as you move into deeper channels. Sarah found the pace refreshing rather than tedious. Once at the islands, your guide will anchor at two or three snorkel sites depending on tides and conditions. The reef here isn't pristine coral garden, but there's good fish life and it's clear enough to see down. You'll return to one island around midday for lunch—typically simple Thai fare cooked fresh. The afternoon repeats the pattern: snorkel, cruise, snorkel again. By hour eight you're heading back, watching the light change on those same limestone cliffs. It's leisurely, not high-octane.

Good to know
This trip ticks the box for everyone wanting proper scenery without the full-day commitment of island-hopping tours. The longtail pace suits photographers and anyone who doesn't want to feel rushed. Snorkel gear is included and fits most people reasonably. Lunch and water are covered, which saves money. English-speaking guide means no navigation confusion. The Koh Hong group genuinely is one of Krabi's highlights, and you're seeing it from the water.
The operator excludes "Hong Island" itself from the itinerary—check what that means for your group (you may not land on the main island). The reef snorkelling is decent but not world-class. Not suitable for pregnant women, those with spinal issues, or poor cardiovascular health. Longtail boats have no shade canopy on some days—sunburn risk is real. Group sizes aren't specified; could be cosy or crowded. Early-morning start typical for these tours. Lunch is basic, not a highlight. Bring a rash shirt, strong sunscreen, and a dry bag for valuables. The boat ride can be bumpy in rough seas.
