About this tour
When Mia from our BugBitten team took this Krabi tour, the drawcard was the tidal magic at Chicken Island—a white sandbank that appears and vanishes with the day's tides, briefly linking three islands on foot. The eight-hour run from Ao Nang sweeps across the Andaman in a traditional longtail, hitting snorkeling spots, limestone quirks (including a limestone arch shaped like a chicken's head), and the odd underwater tunnel if conditions allow. It's a fairly full day with decent company—a mix of keen snorkelers and island-hoppers—and the longtail vibe keeps things relaxed.
Highlights
- Sandbank connects three islands at lowest tide each day
- Chicken-head limestone formation rises above turquoise water
- Longtail boat weaves through narrow sea channels and caves
- Snorkeling in sheltered Andaman spots with decent visibility
- Thai lunch served on the boat overlooking open ocean
- Tour stops at genuinely quiet, undeveloped beaches
- Small group feels intimate rather than cattle-herded
What to expect
The day starts early with a hotel pickup from Ao Nang, then you're driven to the longtail dock. Once afloat, expect a mix of cruising and swimming—the boat captain knows the route well and stops at two or three snorkeling zones where the coral and fish life are solid but not spectacular. The real event is timing the low tide at Chicken Island; the sandbank does appear, and you can genuinely walk across to the neighbouring islands. The underwater tunnel swim is conditional on tide and season, so don't bank on it entirely. Lunch arrives mid-afternoon on the boat—simple, warm Thai fare that tastes better at sea than it has any right to. The pacing feels unhurried, which is refreshing; there's time to soak in the views rather than tick boxes.
What surprised our team was how few tourists know about this spot. You'll see longtails, but not the carnival feel of Phuket beach clubs. Water clarity depends on season (dry season is cleaner), and the limestone scenery—especially those oddly shaped rocks—photographs well without feeling manufactured.

Good to know
If you love tidal phenomena and quirky geology, this delivers. Small groups mean the guide isn't herding 40 people. The longtail itself is half the charm—authentic, slow enough to appreciate the Andaman's moods. Snorkelling is included and the sandbank walk is genuinely unusual. Lunch is decent, and the whole experience feels less packaged than other Krabi offerings.
It's physically active—lots of climbing in and out of boats, swimming, and walking on wet rocks. Early starts aren't for everyone. The underwater tunnel is weather and tide-dependent, so don't expect it as a given. National park fees (200THB adults, 100THB kids) aren't included and catch some folk off guard. If you're booked from Klong Muang, Tub Kaek, or Krabi Town, add 100THB per person for transfers. Not suitable for pregnant travellers, those with spinal issues, or poor cardiovascular health—the tour operator is clear on that. Bring reef-safe sunscreen; the exposure is relentless.
