Day one, ride a longtail boat from Ao Nang across to Railay. Day two, spend a full day out on the Andaman — the classic 4-Island tour or the Hong Islands lagoon. Day three, head inland to soak in the Emerald Pool and climb 1,237 steps to a hilltop Buddha. Three days is exactly enough to see Krabi's sea and its jungle interior.
Most visitors come to Krabi for the beaches and the islands, and fair enough — they are the headline act. But give the province three days and you get to see its other side: inland Krabi hides an emerald-green pool in the rainforest, a natural hot-spring waterfall you can actually sit in, and a hilltop temple that charges 1,237 steps for a 360-degree view.
This plan is built for a first visit to Krabi, with one clear theme per day: day one for Ao Nang and Railay, day two for a full day on the water, day three for the jungle interior (or a Phi Phi swap if you have not had enough sea). Base yourself in Ao Nang and let longtail boats, songthaews and tour minivans do the moving — Krabi has no metro and no train, so everything runs by road and by water.

Krabi's main beach town · a 15-minute longtail ride · Phra Nang Beach under the cliffs — an unhurried first day that introduces your base, then crosses to the province's most famous peninsula.
Start gently in Ao Nang, the main tourist base of Krabi — have breakfast, walk the beachfront road and watch the longtail boats lined up on the sand (the classic Krabi photo). If you want a proper coffee before setting off, the area has plenty of cafés — see our picks in the Krabi café guide. Then head to the boat-ticket counters on the beach and buy a longtail ticket to Railay — a limestone peninsula with no road access at all. Boats are the only way in.
The crossing takes only about 15 minutes, but the view on the way is limestone cliffs rising out of the sea one after another. The moment the boat slides onto Railay West, you will understand why everyone talks about this place. For more on the town itself, read our Ao Nang guide.
Give the whole afternoon to the peninsula. Start on Railay West, a long curve of sand framed by cliffs on both ends, with shallow water that is easy to swim. Then take the walking path across the peninsula — about 10–15 minutes — to Phra Nang Beach, which many people rate the most beautiful beach in Krabi: the Phra Nang shrine cave sits under the headland, and the cliffs around the bay have climbers from all over hanging off them all day. Railay is one of Asia's best-known rock-climbing spots.
The one thing to watch here is the macaques — there are many and they are quick. Hold food or a plastic bag in view and it may get snatched, so keep everything zipped away and you will be fine. For all four beaches, the walking routes and the photo angles, read our Railay guide.
Take a longtail back to Ao Nang in the late afternoon (return boats run until around six, depending on the season and the swell — ask your boatman on the way over). If the sky is clear, the sunset off Ao Nang beach holds its own against anywhere in Thailand. Watch it from the sand, then go find dinner — seafood restaurants line the beachfront road, most selling by weight, so always check the price before ordering. Our picks are in the Krabi seafood guide. Walk it off afterwards at the Ao Nang night market.
A full day on the Andaman — take the classic 4-Island longtail tour, or chase clearer water to the Hong Islands lagoon by speedboat. Pick one and do it properly.
The 4-Island tour is the trip most visitors to Krabi take, and it earns its reputation — Poda Island with its white-sand shallows, Chicken Island with the rock formation shaped like a chicken's neck, Tup and Mor islands, where at low tide the Thale Waek sandbar surfaces and lets you walk between the islands (the highlight of the trip — how much appears depends on the day's tide), and a final stop at Phra Nang Beach, the one you strolled yesterday, this time arriving from the sea.
The join-in longtail version is the classic — cheaper, and more Krabi in spirit. If you get seasick easily or want to save time, speedboat departures exist too. Every trip is compared in detail in our Krabi island-hopping guide.
If you want clearer water, thinner crowds and a different kind of memory, choose the Hong Islands northwest of Ao Nang. The highlight is the lagoon: the boat slips through a gap in the cliff wall into still, emerald-green water enclosed by rock on every side. Then there is the 360-degree viewpoint, a stair climb that opens onto islands scattered across the sea as far as you can look. Most trips run by speedboat, since the Hong group sits further out than the 4-Island circuit.
With one sea day, one tour is enough — take the 4 Islands if you want beaches, the sandbar and a lighter bill; take the Hong Islands for the lagoon, the high viewpoint and clear water without queueing for photos.
Most island tours drop you back at the hotel around four or five. Rinse off the salt and pick your evening: if you cannot face going anywhere, eat on the Ao Nang beachfront again — but if you have energy left, take a songthaew into Krabi Town for the real local table: southern-style khanom jeen noodles with fiery curries, sour gaeng som, and night-market desserts, all at prices well below the tourist strip. Our picks are in What to eat in Krabi — and if it is a weekend, the Krabi walking street adds one more loop to the night.
A clear emerald pool in the forest · a natural hot-spring waterfall · a hilltop temple — the last day turns its back on the sea and shows you the Krabi most visitors skip.
Today points inland, to Khlong Thom district about an hour and a bit from Ao Nang. The Emerald Pool is a natural blue-green pool in the forest, pleasantly warm and — the good part — you can actually swim in it. From the entrance it is a forest walk of roughly 800 m to 1.5 km depending on the trail you pick, on a clear and easy path. Arrive as early as you can: before 10:00 the water is at its clearest and the crowds at their thinnest. Tour groups start arriving mid-morning.
Deeper in lies the Blue Pool, a blue so intense it hardly looks natural — but it opens and closes with trail conditions and the season, is sometimes off-limits, and is for looking only, no swimming. Check on the day. Trail details, fees and the best timing are in our Emerald Pool + Hot Springs guide.
A few minutes from the Emerald Pool is the Khlong Thom Hot Spring Waterfall — warm mineral water around 38–40°C spilling down a series of small limestone basins you can sit in, like whirlpool tubs the forest made itself. Alternate between the warm pools and the cool stream below, and two days of climbing, hiking and swimming melt out of your shoulders. Keep each soak to 15–20 minutes, and skip the midday heat.
On the way back, if your legs still agree, stop at Wat Tham Suea — the Tiger Cave Temple, about 20 minutes from Krabi Town. Its famous stairway climbs 1,237 steps to a large Buddha at the summit and a 360-degree view across limestone karst, palm plantations and out to the sea. Starting around 16:00–16:30 works well — the heat eases and you catch the late golden light up top. The climb is genuinely steep, with some very tall steps; allow 1.5–2 hours up and down, carry water, dress modestly, and watch for monkeys the whole way. The full climbing playbook is in our Tiger Cave Temple guide.
Come down and celebrate with a farewell dinner in Krabi Town — the riverside night market or a good southern-Thai restaurant — then fly out tomorrow without rushing.
For a first trip, pick Ao Nang — next to the longtail piers, full of restaurants, and tours pick up at your door. For quiet and the big cliff views, sleep on Railay (reachable only by boat). On a budget, or chasing cheap local food, choose Krabi Town. Every area is compared in Where to stay in Krabi and the 10 best hotels.
Krabi has no metro and no train — the workhorses are songthaews (Krabi Town ↔ Ao Nang ~฿50–60) and longtail boats (Ao Nang ↔ Railay ~฿100–150). Island and inland tours include hotel minivan transfers. Grab works but cars are limited, so allow waiting time; scooters rent for ~฿250–350/day if you ride confidently. See Getting around Krabi and airport transfers.
Nov–Apr is the golden window: calm seas and island trips running almost daily (hotel rates peak to match). May–Oct is the southwest monsoon — rain in bursts, rougher water, tours cancelled on some days, in exchange for lower prices and fewer people. April is hottest and lands on Songkran.
