TL;DR: A realistic Krabi itinerary bases you in Ao Nang and works best over four days: a half-day boat trip to Railay Beach (฿100/~US$3 each way, 10-15 minutes), a full-day 4 Islands tour (฿800-1,000/~US$24-30 by longtail or speedboat, plus a ฿400/~US$12 national park fee), an inland day pairing Tiger Cave Temple’s free 1,237-step climb with a swim at the Emerald Pool (฿400/~US$12 entry), and a full-day Hong Islands tour (฿849-1,299/~US$26-39, plus a ฿300/~US$9 park fee) for a quieter lagoon and viewpoint. On three days, skip Hong Islands and keep the 4 Islands tour, since stacking both full-day boat trips into a short visit leaves no real time for Ao Nang or Railay themselves. Both island tours run roughly 6-7.5 hours door to door with an 8-9am pickup and a 3-4:30pm return, so don’t plan anything else those days. All prices ฿33 = US$1 (July 2026).
If you’re building a Krabi itinerary from scratch, the hardest part isn’t finding things to do, it’s fitting them together without burning out. Railay Beach, the 4 Islands tour, the Hong Islands, Tiger Cave Temple and the Emerald Pool are all genuinely worth your time, but two of them (the island tours) eat a full day each, and cramming everything into three days usually means seeing less, not more, of each. This guide lays out a day-by-day plan based in Ao Nang, with honest advice on what pairs well, what to skip if you’re short on time, and real operator pricing and hours checked against current 2026 sources at the end.
How this itinerary works
Base yourself in Ao Nang: it’s Krabi’s transport hub, and every boat in this itinerary leaves from its pier. Railay, the 4 Islands and the Hong Islands are all reached from Ao Nang, and it has by far the widest choice of hotels and restaurants in the province; see where to stay in Krabi for a fuller area comparison. This plan runs four days, one for Railay, one for the 4 Islands, one inland day for Tiger Cave Temple and the Emerald Pool, and one for the Hong Islands, but it flexes down to three by dropping the Hong Islands day.

| Day | Focus | Rough cost per person | Timing |
|---|---|---|---|
| Day 1 | Settle into Ao Nang, half-day/afternoon at Railay Beach | ฿100-200 (~US$3-6) boat + lunch | Boats run 8am-6pm |
| Day 2 | Krabi 4 Islands tour | ฿800-1,000 tour + ฿400 park fee (~US$36-42) | ~8:30am pickup, 3pm return |
| Day 3 | Tiger Cave Temple (sunrise) + Emerald Pool | Free climb + ฿400 entry (~US$12), or ~฿1,100 (~US$33) packaged tour | Early morning to mid-afternoon |
| Day 4 (4-day trips) | Hong Islands tour | ฿849-1,299 tour + ฿300 park fee (~US$35-48) | ~8am pickup, 3-4:30pm return |

Day 1: Settle into Ao Nang, then Railay Beach
Give yourself a light first day. Check into Ao Nang, walk the beachfront promenade, and don’t try to pack in a full-day tour on top of travel fatigue. By early-to-mid afternoon, walk to Ao Nang’s pier and take a longtail across to Railay Beach: the crossing takes about 10-15 minutes for ฿100 (~US$3) one-way, and boats leave once roughly eight passengers have boarded, running from about 8am until 6pm.
Railay doesn’t need a full day to make an impression. Land at Railay West, walk the beach, then follow the short path south to Phra Nang Cave Beach, the most photogenic stretch of sand on the peninsula and home to the Phra Nang fertility shrine. Two to three hours is enough to see both beaches properly; if you’re feeling ambitious and it’s not too late in the day, the viewpoint and lagoon hike from the Railay East side adds a genuinely strenuous rope-assisted scramble with a payoff view over the whole peninsula. Head back to the pier in good time, since boats thin out and get pricier after dark, and you don’t want to be negotiating a private longtail back to Ao Nang on your first evening.
One overlap worth knowing about now: Phra Nang Cave Beach is also one of the four stops on tomorrow’s 4 Islands tour. Seeing it today on your own schedule, rather than as a rushed 30-minute stop squeezed between boatloads of other tour groups tomorrow, is arguably the better way to experience it.
Day 2: The Krabi 4 Islands tour
This is a full boat day, so treat it as the day’s only plan. Most operators run a shared longtail tour for ฿800 (~US$24) per adult or a speedboat version for ฿1,000 (~US$30), both with pickup around 8-8:30am from Ao Nang hotels, departure from the pier shortly after, and a return to Ao Nang by around 3pm, roughly 5.5-6 hours all told. On top of the tour price, budget a separate ฿400 (~US$12) national park fee per adult (฿200/~US$6 for children), paid in cash to your guide, since Thai regulations forbid folding it into the advertised price.
The four stops are Phra Nang Cave Beach (which you’ll have already seen from Railay yesterday), Chicken Island (Koh Kai), Tup Island and Poda Island, with many tours also swinging by tiny Koh Mor for the tide-dependent sandbar walk between it and Tup. Snorkelling gear, lunch and drinking water are standard inclusions. For the full breakdown, longtail versus speedboat, half-day options, and the honest read on crowds and the sandbar’s tide dependency, see the dedicated Krabi 4 Islands tour guide.
Back in Ao Nang by mid-afternoon, you’ll have the rest of the day free; a quiet dinner and an early night sets you up for the temple climb tomorrow.
Day 3: Tiger Cave Temple and the Emerald Pool
This is the inland day, and it works because both stops sit away from the coast, unlike every other day in this plan. Start early: Tiger Cave Temple (Wat Tham Suea) is about 20km from Ao Nang, a 30-minute drive, and its 1,237-step summit stairway has essentially no shade, so climbing at or near sunrise, or arriving by 7-8am, makes a real difference to how hard it feels. Entry is free (donation boxes fund the stairs’ upkeep), and most people take 35-90 minutes each way. At the top, a large golden Buddha and a genuine panoramic view over Krabi’s karst landscape reward the climb.
From there, head to the Emerald Pool (Sa Morakot), roughly 75km from Ao Nang or 55km from Krabi Town, open about 8:30am-4:30pm, with foreign adult entry at ฿400 (~US$12) and ฿200 (~US$6) for children. Be realistic about the drive: this is a genuine half-day-plus commitment on top of the temple, not a quick add-on, so most visitors without their own car or scooter book a packaged half-day tour from around ฿1,100 (~US$33) that bundles in the nearby Hot Springs and transport, sometimes with Tiger Cave Temple included too. Self-driving both stops in one day on a rented scooter is possible but makes for a long, sun-heavy day covering close to 100km of driving in total, so weigh your own comfort on unfamiliar roads before committing to it solo.
If a full inland day feels like too much on top of two island days already, it’s the easiest single day to cut from this itinerary, especially on a three-day trip.
Day 4: The Hong Islands (four-day trips)
Only add this day if you have four days. The Hong Islands sit inside Than Bok Khorani National Park and run on a similar structure to the 4 Islands tour: a shared longtail costs roughly ฿849-899 (~US$26-27) per adult, or ฿999-1,299 (~US$30-39) by speedboat, both with an 8-9am pickup and a return between about 2:30pm and 4:30pm. The separate national park fee is ฿300 (~US$9) per adult and ฿200 (~US$6) per child, lower than the 4 Islands’ ฿400 fee, and it covers every island in the group for the day.
The appeal here is different from the 4 Islands tour: a genuinely sheltered hidden lagoon at Hong Island itself, a steep 360-degree viewpoint climb of roughly 419 steps through jungle, and stops at Lao Lading (Paradise Island) and Pakbia Island, both quieter than the 4 Islands’ more famous, more crowded beaches. Because this is your second full boat day of the trip, don’t schedule anything else, and don’t be surprised if it feels a little repetitive in structure even as the scenery differs, more snorkelling, another lunch stop, another viewpoint. That’s the honest trade-off of doing both island tours rather than one.
Doing it in three days instead of four
Cut the Hong Islands day and keep everything else. The 4 Islands tour is the more iconic, more frequently booked route, so it’s the better single island-tour choice if you’re only doing one. That leaves Day 1 (Ao Nang and Railay), Day 2 (4 Islands) and Day 3 (Tiger Cave Temple and the Emerald Pool) exactly as above, which is a full but genuinely doable three days without repeating the same kind of boat day twice.
If three days still feels tight, the next thing to compress is the inland day: pick either Tiger Cave Temple or the Emerald Pool, not both, since the roughly 100km of combined driving is the single biggest time cost in this itinerary. A sunrise Tiger Cave Temple climb before a mid-morning flight out, for instance, is a realistic half-day even on a short trip; the Emerald Pool, given its distance, is not.
Which order should the days go in?
The sequence above, Railay first, then the 4 Islands tour, then the inland day, then Hong Islands, isn’t arbitrary. Doing Railay before the 4 Islands tour means you’ll recognise Phra Nang Cave Beach on day two rather than seeing it twice as a novelty; putting the inland day after both boat days gives your body a break from early pier pickups and boat spray; and Hong Islands, if you’re doing it, works best last, since it’s the quieter, less essential of the two island tours and a good note to end on rather than the one you rush to fit in first.
Weather can force a reshuffle regardless of plan: Krabi’s monsoon runs roughly May-October, and rough Andaman seas most often disrupt the boat days rather than the inland or Railay days, so if you’re travelling in that window, keep some flexibility around which day is which. See the best time to visit Krabi for the fuller seasonal breakdown, and check what’s on in Krabi before you land in case something worth timing around is happening while you’re there.
Honest downsides
- Two full-day boat tours back to back is a lot. Both the 4 Islands and Hong Islands tours run 6-7.5 hours with an early pickup, snorkelling, lunch and a return mid-to-late afternoon; doing both on consecutive days works, but don’t expect much energy left for evenings out.
- The inland day is a genuine commitment, not a quick stop. Between Tiger Cave Temple and the Emerald Pool you’re covering close to 100km of driving from an Ao Nang base, so treat it as its own full day rather than something you tack onto a boat day.
- National park fees add up and are never included. Budget an extra ฿400 (~US$12) for the 4 Islands day, ฿300 (~US$9) for Hong Islands, and ฿400 (~US$12) for the Emerald Pool, all paid separately in cash on top of whatever the tour or entry ticket costs.
- Overlap is real if you don’t plan around it. Phra Nang Cave Beach shows up on both the Railay day and the 4 Islands tour; going in aware of that, rather than expecting four entirely distinct beaches, sets the right expectations.
- Monsoon season (roughly May-October) can rearrange this whole plan. Rough seas most often affect the two boat days; keep a spare day or flexible dates if you’re travelling outside November-April.
Bottom line
Four days gives Krabi’s best-known stops room to breathe: a relaxed Railay afternoon, the classic 4 Islands tour, an inland day at Tiger Cave Temple and the Emerald Pool, and the quieter Hong Islands to finish. On three days, drop the Hong Islands and keep the rest, since two full boat days plus a long inland day is already a packed trip. If you want to extend further, a Phi Phi day trip is a natural fifth day from either Ao Nang pier. For the wider province, pair this with things to do in Krabi, sort your base with where to stay in Krabi, and time the trip against the best time to visit Krabi before you book anything.
