## What is Than Bok Khorani?

**Than Bok Khorani** is a marine national park in **Ao Luek** district in northern Krabi province. It covers stretches of land with karst cliffs, caves and forest, plus islands out at sea — including **Koh Hong**.

The best-known part is the **forest garden by the entrance**. An underground river emerges from under a limestone cliff and spreads over steps and **emerald pools** beneath the trees. Wooden footbridges cross the water, and you can swim in the cool shade.

> **The garden and the mangroves are separate trips** The forest garden with its pools is a few minutes' walk from the ticket office, and an hour or so is enough. The caves and mangroves are a separate outing: you go by kayak or longtail from piers around Ao Luek, and the boat is paid for separately from park entry. To see both, allow half a day or take a tour.

## How the park works

At the entrance are a ticket office, parking and toilets. Entry is paid: according to guides, about **300 baht** per foreign adult and 100–150 per child, in cash; sources also give other amounts — check on the spot. The park is open **roughly 8:00 to 16:30**.

You can swim in the forest-garden pools — the water is cool and clear, and not deep. Weekday mornings are especially quiet. The water's colour is brightest on sunny days and in the dry season.

## What to see and do

- **Emerald pools** and cascades in the forest garden.
- **Swimming** in cool water under the trees.
- **Wooden footbridges** and paths over the stream.
- **Mangrove kayaking** from Bor Thor pier.
- **Tham Phi Hua To cave** with prehistoric paintings — by boat.
- **Tham Lod cave** — a through-cave you paddle under by kayak.

## How to get to Than Bok Khorani

1. **From Krabi Town** — ≈ 45 km north on Highway 4, about 40 minutes by taxi or scooter.
2. **From Ao Nang** — ≈ 52 km, about 50 minutes; a half-day taxi is easiest.
3. **On an Ao Luek kayaking tour** — hotel pick-up, mangroves, caves and often the pools.
4. **By scooter** — paved roads via Highway 4 and then through Ao Luek.
5. There are no regular buses to the park.

## On your own or on a tour

|  | Independently | Kayak tour |
| --- | --- | --- |
| What you see | The forest garden and pools | Mangroves, caves, often the pools |
| Time | 1–1.5 hours on site | Half a day or a day |
| Entry | Pay at the ticket office | Often included — check |
| Transfer | On your own | Hotel pick-up |

## How long do you need?

Allow **1–1.5 hours** for the forest garden and pools. With mangrove and cave kayaking it's **half a day**, and nearly a full day with the drive from Ao Nang.

Come on a weekday morning: the water is calmer, there are fewer people, and you can stop at **Tiger Cave Temple** on the way back.

## Is Than Bok Khorani worth visiting?

Yes, if you want quiet nature: emerald water in the forest, mangroves and caves with ancient paintings show a very different Krabi from the beaches.

The YesGo take: the garden itself is small, and foreigners pay much more than locals. Pair it with mangrove kayaking — then the trip is worth the drive.

## Before you go: checklist

- [ ] Cash for entry and the boat
- [ ] Swimwear and a towel
- [ ] Water shoes
- [ ] Insect repellent
- [ ] A dry bag for your phone on the kayak

- Mangrove kayaking is the best add-on to the garden.
- Bring cash for entry and the boat.
- A dry bag for your phone on the kayak.
