About this tour
When Sarah from our team took this half-day speedboat tour out of Phuket, we hit the water early and spent five hours island-hopping through Krabi's limestone-studded seascape. The boat clips along between Koh Thap and Koh Ghai (Chicken Island), with stops for swimming and snorkelling in gin-clear shallows, a packed lunch onboard, and a walk through Diamond Cave's wooden-plank maze. It's a proper rush of wind and spray, packed with other travellers keen for the same thing — not quiet, but genuinely fun.
Highlights
- Speedboat acceleration and sea spray between palm-fringed limestone cliffs
- Koh Ghai's bird-like silhouette actually does look like a chicken
- Snorkelling stops in warm, shallow, reef-patchy water
- Diamond Cave's twisted wooden walkways and cathedral-scale rock chambers
- Lunch served onboard — simple, warm, edible
- Hotel pickup and drop-off included; no faffing about
- Guide commentary adds context without overdoing the sales pitch
What to expect
You'll be picked up early from your hotel and driven to Phuket's speedboat dock, where you'll board with thirty-odd other tourists. The engine fires up and you'll feel real acceleration — it's genuinely thrilling, though not for the queasy. The boat stops at Koh Thap first for a swim and snorkel; the water's warm and visibility decent, though don't expect pristine coral gardens. Koh Ghai's the photo moment — its shape really does resemble poultry, and it's oddly satisfying to see it. Lunch arrives mid-morning, nothing fancy but fresh enough.
After eating, you'll dock at Railay Beach for a breather on the sand, then motor to Diamond Cave for the final hour. It's crowded in there — dozens of visitors shuffle through on wooden walkways, climbing stairs past stalactites and chamber after chamber of pale rock. The cave's impressive in scale but the novelty wears fast. The whole day feels organised and efficient; you're never waiting around, but you're also never alone anywhere.

Good to know
Sarah found the sheer pace and wind-in-your-face sensation genuinely exhilarating — if you love speedboats, this delivers. The snorkelling is hassle-free and the water's inviting. Hotel transfers save you coordinating transport, and lunch is included, which takes the edge off pricing. It's suitable for most fitness levels, and the guide speaks English fluently.
It's an early start from Phuket (pre-dawn), so expect tiredness. Crowds are substantial — you're packed onto the boat and shuffling through Diamond Cave with dozens of others. The cave, while impressive, is touristy and cramped. The tour isn't recommended for anyone with spinal issues or poor cardiovascular health due to the boat's vibration and speed. Phi Phi National Park isn't included, so if that's on your wish list, this won't tick it. Gratuities and personal spending aren't covered. Peak times (December–February) will be even busier.
