Bukit Keplu is 28 limestone sport routes in Kodiang, Kedah, from 5c to 7b+, but it starts to get hot around 3pm. Two ways in, a community report of fatal rockfall risk that puts a helmet on the belayer, and parking that must not block the farm road.
Two karst limestone hills in the rice fields of Perlis, 77 sport routes from 4a to 8c+ across the West, South and Robot Wall sectors: the railway station is a 376 m walk away and access is free. Most bolts date from the 2007 expedition and their material is still unpublished; the South sector is restricted after an ancient mural was found.
Fairy Caves above the village of Bau, 30 to 50 km from Kuching, has 88 routes from 5a to 8c, and the community-managed Batman Wall holds the lion's share with 49 routes from 6a to 8c. Three things shape the trip: the Fairy Cave Wall and Nepenthes Wall are currently closed, the Zoo Wall renovation note stops in 2014, and two theCrag pages quote different fees.
A cave crag 33 km north of Kangar in Perlis: 36 routes, 63 ascents, five sectors (A+B, C, D, E, F) between 15 and 43 m, grades from 4a to 6c and above and densest from 5c to 6b. Entry costs a park fee (RM5 for foreigners, RM2 for Malaysians, a 2023 figure) and weekends get busy; the crag page publishes only one named route, so the rest depends on the sector pages and the local climbers.
Gunung Keriang is 37 sport routes in a public recreation park in Kedah, free to climb on walls of 14 to 23 m, with the grades concentrated in the middle bands. The catch is that only one route is published by name, so bring your own topo.
Gunung Lang is 28 mostly sport routes on the east side of a limestone rock in a recreational park in Ipoh, 20 m high. A Grab from the old town is about RM10 for 3 km and shade arrives after noon, but large puddles sit at the base of most climbs, the land is private yet freely accessible, and the forum reported a loose bolt in January 2026.
Two climbable islands off the west coast of Langkawi: a private island with 20 limestone sport routes from 6a to 7a+, and a deep-water bouldering island that needs a chartered boat. Both are private land and you need permission by phone before you travel, or trespassers will be prosecuted. The boat runs 09:00 to 19:00 at odd hours only and costs RM5 each way.
Lubuk Pedati is 35 sport routes on the long Gunung Baling range in Baling, Kedah, spread over four animal-named sectors, with 20 routes in Hornet Section alone. The price is self-driving and a narrow muddy final stretch where the plants scratch your car; the crag page carries no description at all.
Dragon's Horns on southern Tioman is a granite big wall: 14 routes, the longest South Tower line around 360 m, grades from 6a to 7c+. What really shapes the trip is getting onto the island: Mukut has no jetty the public ferry can use, the ferry season runs roughly April to September, and the northeast monsoon from November to February suspends sailings often enough that the rest of the approach is hours on foot through jungle with your gear.
Ulu Piah is 27 limestone routes from 5c to 8b on the Mount Hugh Low massif near Tambun, Perak, across four sectors. Call or WhatsApp the landowner, Haji Hamid (+60 19-573 6787), with your headcount and time before you go; the approach is rough and pothole-ridden so take a high-clearance car, and community reports describe fatal rockfall risk with a helmet required for the belayer.
Malaysia's natural crags fall into three groups: limestone sport climbing in Perlis and the northern states, ten separate walls at Batu Caves north of Kuala Lumpur, and the big walls of Tioman and Sarawak in Borneo. Perlis is driest from January to April, Batu Caves climbs year round but every wall charges and holds up differently, and Tioman ferries run less often from November to February.
North Wall is in Ao Nang town, under five minutes' walk away. All titanium bolts (Hilti 500 glue), 103 routes from 4b+ to 9a, a 50 THB all-day entry fee, gear rental, toilets, and it climbs from September to March. theCrag carries two warnings: you must park outside in a designated spot and not by the pond at the main entrance, and there are thieves targeting climbing gear, phones and cash. Private land, and drilling or chipping the rock is forbidden.
Chiang Dao is red limestone 1.5 hours north of Chiang Mai, with 61 routes logged on theCrag from 5b to 8a+ and 30 of them on the Pha Daeng main wall. The crag sits inside Pha Daeng National Park and is tolerated rather than permitted: rangers very occasionally ask you to leave, and a park closure closes the climbing. The area was shut for fire prevention from 1 March to 15 May 2025.
Chong Phli, also called Spirit Mountain, sits on the Krabi mainland between Ao Nang and town, with 157 routes logged on theCrag from 4b+ to 9a across ten sectors. About 90% of the bolts are titanium with RE-500 glue, some routes use slings because the rock is soft, and every anchor and sling is checked once a year. There is a homestay and community centre at the crag with bungalows, water and toilets — the closest thing to a resort base on the mainland.
Crazy Horse is a limestone sport crag in the Mae On valley east of Chiang Mai, with 289 routes in 22 sectors on theCrag. It is closely bolted, mostly 5s and 6s, and its caves hold 4- and 5-pitch lines, which makes it northern Thailand's best crag for climbing from beginner grades up to 6c. It closed in 2018 over a criminal case between local government offices, and since then it has reopened and had prohibition signs put up again. As of October 2026 there is still no official reopening notice, so when you book the CMRCA shuttle the evening before, ask them face to face whether you can climb.
Koh Tao is Thailand's only real granite bouldering destination, with 496 routes logged on theCrag using Font grades from 1A+ to 8A+, and 123 routes in the Backyard & Frontyard sector alone. But it is a community crag, not an open public resource: some sectors have sensitive access, bolting needs the Koh Tao Climbing Club's permission, and the guidebook is an US$8 app whose revenue goes entirely into route development.
Lampang is northern Thailand's newest crag, developed by CMRCA and 30 minutes from the town. But it sits on military land: you must register with CMRCA in advance and pay for permission, and you can only climb on days when a CMRCA guide is present. theCrag logs 25 routes from 5b to 6c+, there is a lot of loose rock, and you wear a helmet.
Lopburi is a 200-metre limestone tower 160 km north of Bangkok, with 127 routes logged on theCrag from 3a to 8a. Reaching the Temple Area means walking through Wat Pa Suwannahong, and the status is tolerated rather than permitted: since March 2023 a 20-climber daily cap with advance registration, leave before 6pm, say hello to the monks on the way in and out, and donate 20 to 100 THB. The other approach is a 20–30 minute walk to the back of the mountain.
The Nam Pha Pa Yai camp sits about 130 km northeast of Bangkok, with 101 routes logged on theCrag from 4a to 8b. But the biggest wall, River Wall with 65 routes, has been closed since January 2024 over access problems, and theCrag still carries a warning saying it looks shut with no sign of change. The camp still takes bookings and closes from April to June. With the main wall gone, the trip is not worth a special journey.
Railay East sits on the west side of the Phra-Nang peninsula; theCrag logs 314 routes for the whole of Railay, with Muay Thai, the 123 Wall, The Keep, Hidden World and Diamond Cave on this side. From 9am to 4pm is climbing school territory and it is very crowded — theCrag literally says do not come between those hours if you dislike crowds. Many routes run on old expansion bolts, and the three old routes on the left of the 123 Wall plus the four extensions above Kratoy are all marked do-not-climb.
