Base
Sukhothai

Ramkhamhaeng National Park — Khao Luang to locals — is the mountain range that rises straight out of the Sukhothai plain, about 40 km south of the old capital. It is 341 km² of dry evergreen forest, cliffs and waterfalls, with a summit ridge at roughly 1,160–1,200 m and a trail that is short in distance and hard in gradient. Most visitors come for the Khao Luang climb and the giant banyan tree on the way up; the park also holds the Sai Rung waterfall and a botanical garden at the foot of the range. It is a stop for people already in Sukhothai, not a destination on its own.

Where to stay

In the park

Park bungalows

Three units sleeping up to six, booked through the park; the simplest base inside the boundary.

In the park

Summit campsite

Tents and gear for rent at the top, plus a stall selling rice with fried egg, instant noodles and cold drinks.

In the park

Headquarters campsite

Camping at the bottom; bring your own gear, as there is no rental here.

Near the park

Sukhothai town

The widest choice of guesthouses and hotels, 40–60 km (25–37 mi) away.

Safety

Steep, draining climb high

Start early, carry more water than you think you need, and allow 3–5 hours up; the trail is short but one of the steepest in the country.

Slippery trail in the rainy season medium

Wear shoes with grip and use trekking poles from June to September; rock stays wet under the canopy.

Cold nights at the summit medium

From December to January bring a warm layer and a sleeping bag; the top is cold year-round.

No water or food on the upper trail medium

Buy supplies at the headquarters shop before climbing; the summit stall sells only basic food.

Time out

Finding the local time zone…

Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.

Accessibility

  • The headquarters, botanic garden, shop and restaurant are reachable by car with short, level walks.
  • The nature trail is the only walking route with easy gradients; the Khao Luang summit trail is steep and not suitable for limited mobility.

Visiting lightly

  • Carry out everything you carry in; the summit campsite has no waste collection beyond basic bins.
  • Use the park's own bungalows and campsites so fees stay with the park.
  • Do not feed or approach wildlife; banteng and deer are shy and easily disturbed.

Questions people ask

How much does it cost to enter Ramkhamhaeng National Park?

Thai national parks charge two rates: roughly 20–40 baht for Thai adults and about 100–200 baht for foreign adults, with children paying less (2026 estimate, check current rates). Bungalows are around 1,800 baht for up to six people, and camping gear at the summit can be rented.

What are the best hikes in Ramkhamhaeng National Park?

The Khao Luang summit trail is the main one: about 3.7 km, very steep, 3–5 hours up, finishing on a ridge of four summits. The 3 km nature trail from the headquarters is the easy alternative, passing the herb garden, Sai Ngam banyan and Hin Rang waterfall in about two hours.

When is the best time to visit Ramkhamhaeng National Park?

November to January, when the air is dry and cool and the summit is clear; December and January bring cold nights and morning mist. The park is green and quiet in September–October. The summit trail usually closes for part of the hot season, roughly March to May, so confirm before travelling.

Can I climb Khao Luang without a guide?

Yes. The trail is marked and most people walk it independently, as a day trip or with a night at the summit campsite. Porters can be hired, but they run out on busy weekends.

Is the summit trail open all year?

No. It usually closes during the hot season, with the exact dates changing each year. Check with the park before you plan a climb in March, April or May.

Where can I sleep in or near the park?

Inside the park there are three bungalows sleeping up to six, a campsite at the headquarters, and a campsite at the Khao Luang summit with gear rental. Sukhothai town, 40–60 km away, has the widest choice of guesthouses and hotels.

Do I need a car inside the park?

For the waterfall and the far corners, yes — the attractions are spread out and there is no shuttle. The headquarters, botanic garden and nature trail are walkable once you arrive.
