Once you’ve done the Four Islands, Krabi opens up. There’s a quieter island group most people prefer, a pair of jungle swimming spots inland, and a hilltop temple with the best view in the province. These are the day trips worth building in beyond the headline island loop, with what each costs and how to reach it.
The short version
- Hong Islands — quieter and, for many, prettier than the Four Islands; a hidden lagoon inside the cliffs. Speedboat ~฿1,000–1,250 plus a ฿300 park fee.
- Emerald Pool & hot springs — a clear jungle spring you can swim in, plus natural warm rock tubs. Modest entry fees; often combined.
- Tiger Cave Temple (Wat Tham Suea) — 1,200-plus steps to a hilltop Buddha and a huge view. Free entry.
- Water or jungle? Islands need calm sea; the inland spots are your wet-day plan. See best time to visit.
- Book boat trips through activities; base in Ao Nang for pickups.
Hong Islands
The best island day after the Four Islands, and quieter. The Hong group (Mu Ko Hong) sits offshore in a marine park, and its signature is “the Hong” itself — a hidden lagoon enclosed by a ring of limestone cliffs, entered through a narrow gap at the right tide, where the water goes flat and jade-green. There’s a viewpoint hike on the main island, good snorkelling, and beaches with far fewer people than the Four Islands loop.
- How: speedboat or longtail day tour from Ao Nang, with hotel pickup.
- Price: about ฿1,000–1,250 (US$29–37) per adult for a group speedboat, plus the ฿300 national park fee (฿100 child) paid at the pier.
- Best for: a second island day, snorkellers, and anyone who found the Four Islands too busy.
If you’re choosing between them, do the Four Islands first for the classic loop and the sandbar, then the Hong Islands for the quieter, arguably more beautiful follow-up.
Emerald Pool & hot springs
An inland pairing in the Khao Phra Bang Khram forest, about an hour from Ao Nang, and the best non-beach half-day in Krabi.
The Emerald Pool (Sa Morakot) is a clear, jade-coloured natural spring you can swim in, fed by the jungle, with a short trail on to the “Blue Pool” — a vivid blue mineral pool that’s for looking, not swimming. It’s a proper forest walk-in, cool and green.
The hot springs (Namtok Ron) nearby are natural rock pools of warm mineral water tumbling through the jungle — a good soak, and even better after the Tiger Cave steps.
- How: they’re awkward to reach without a car, so most people take a combined half-day tour that handles the driving; a private car or a confident scooter rider can do it independently.
- Cost: entry fees are modest but add up — budget roughly ฿200 for the Emerald Pool as a foreigner and less again for the hot springs, plus small parking fees. Posted rates vary, so carry cash and don’t be surprised by a change.
- Best for: a break from the sea, families, and green-season days when the jungle is at its best.
Tiger Cave Temple (Wat Tham Suea)
A working forest monastery on the edge of Krabi Town, famous for the climb: 1,200-plus steep concrete steps up a limestone hill to a golden Buddha and a 360-degree view over Krabi’s karst plains and the sea beyond. It’s a genuine effort — allow around 40 minutes up in the heat, with water and a rest or two — but the view from the top is the best in the province, especially early when mist sits over the plains.
- How: songthaew from Krabi Town (about ฿50), or from Ao Nang (about ฿150); a scooter or taxi is easiest. The songthaew drops on the road, leaving a short walk to the entrance.
- Cost: entry is free (donations welcome).
- When: go at opening, before the heat builds and the steps bake. Dress respectfully — it’s an active temple; cover shoulders and knees at the shrines.
- Best for: early risers, view-hunters, and pairing with the Emerald Pool on an inland day.
Building an inland day
The Tiger Cave Temple, Emerald Pool and hot springs sit roughly on the same side of Krabi and pair naturally into one day: temple at dawn, pools and springs through the middle of the day, back for a night-market dinner. A combined tour ties them together and solves the transport; doing it yourself needs a car or scooter and an early start. This is also the ideal use of a cloudy or drizzly day, when the islands aren’t at their best.
Kayaking the mangroves and sea caves
A gentler day out, and a good one for families or a break from boats and steps. Around Ao Thalane and Bor Thor, north and east of Ao Nang, you paddle through mangrove channels and into karst caves and hidden lagoons, some with prehistoric rock paintings. It’s calm, shaded and low-effort — the tide does much of the work — and the wildlife (mudskippers, monkeys, kingfishers) is part of the appeal. Half-day trips run roughly ฿700–1,000 with a guide, and it’s one of the few options that’s fine in light rain, which makes it a solid green-season pick.
Which day trip to pick
If you’ve done the Four Islands and want one more day, here’s the quick logic. Choose the Hong Islands if you want more island and sea and found the Four Islands too busy. Choose the inland day (temple, Emerald Pool, hot springs) if you want a complete change from the beach, or the weather has turned against the boats. Choose kayaking if you want something calm and easy, or you’re travelling with kids. Choose Phi Phi only if its famous scenery is a genuine must-see and you’ll book an early boat. You can’t really go wrong, but matching the trip to the weather and your energy is what makes the day.
Farther afield
Krabi is a springboard for the wider Andaman. In the dry season, ferries and speedboats run day trips and onward hops to Koh Lanta, Koh Jum and, for the willing, Phi Phi — covered in its own Phi Phi day trip guide. If Krabi is one stop on a longer island route, these connections make it an easy base.
Practical notes for day trips
A few things smooth out any of these. Carry cash in small notes — park fees, entry charges and vendors are all cash-only, and the posted foreigner rates change, so keep a buffer. Start early: the boats and the temple are both far better before the mid-morning crowds and the heat. Pack for the specific trip — sun protection and a dry bag for the islands, closed shoes and modest cover for the temple, swimwear for the pools. And keep an eye on the sea and sky: island days live and die on the weather, while the inland trips are your reliable wet-day fallback. Booking a combined tour handles the logistics; going independently needs a scooter or car and a bit more planning.
How the day trips fit
Slot a second island day (Hong Islands) and an inland day (temple, pool, springs) around your Four Islands trip and you’ve got the best of Krabi in three or four outings — the 3-day itinerary shows the shape. Base in Ao Nang for the easiest pickups, compare rooms on the hotels list, and book the boat days a day ahead through activities.
