Ranked by popularity — out of Pai to see the real thing
Ordered by how popular they are, with an honest note on which is half a day, a full day or an overnight, and who it suits.

If you pick one place to drive out to from Pai, most people choose Pang Ung. This is the still, clear reservoir ringed by rows of pines, with a thin layer of mist drifting over the water at first light — the scene people mean when they call somewhere the "Switzerland of Thailand". It's a royal-project reservoir in Mok Cham Pae, in Mae Hong Son town district.
The best time is a cool-season dawn, when the mist is thick and mirrored in the water. There's a campsite to stay overnight and watch the morning come up over the lake; if you don't stay, you can still drive up for a coffee mid-morning, but you'll miss the mist. It's very close to Ban Rak Thai, so the two are usually done as one trip. For the full overview, read our things to do in Pai guide.

Drive a little past Pang Ung and you reach Ban Rak Thai (formerly Ban Mae Aw), a Yunnanese-Chinese village set around a reservoir near the Myanmar border, founded by former Kuomintang (93rd Division) soldiers who settled here. Clay houses line the water, tea grows on the hills around the village, and the whole place feels like a small corner of Yunnan.
What people come for is to sit and sip fresh oolong tea in the lakeside tea houses, eat braised pork leg with mantou buns and black-chicken herbal soup, rent a Chinese costume for photos, and stroll around the water. Stay a night and you'll get the dawn mist, the same as Pang Ung. The Yunnanese culture here is real and worth respecting — it's a living community, not just a photo set.

North of Pai is Tham Lod Cave (the cave the river runs through), at Soppong — a big cave with a stream flowing right through the middle. The fun part is touring it on foot behind a guide carrying a gas lantern, then riding a bamboo raft along the stream into the cave, not just walking through. Inside there are stalactites and stalagmites in odd shapes, ancient teak 'coffin cave' coffins on the ledges, and big fish in the clear water.
The other highlight a lot of people miss is the evening, around 5.30–6 pm, when tens of thousands of swifts pour back into the cave as the bats stream out to hunt — a dark, swirling river across the sky at the cave mouth, genuinely hair-raising. Arrive in the afternoon and stay until dusk to catch it. It pairs well with the Sai Ngam hot spring on the same road.
Pai sits halfway along the Mae Hong Son loop, the ring of mountain road Chiang Mai–Pai–Mae Hong Son–Mae Sariang–Chiang Mai that motorcyclists from around the world come to ride. Carry on from Pai another 100 kilometres or so and you reach Mae Hong Son town, a small place cradled in mountains with a clear Shan (Tai Yai) character.
In town there's Wat Chong Kham and Wat Chong Klang beside Nong Chong Kham lake, whose reflections look lovely at dusk, and Wat Phra That Doi Kong Mu on the hill, with a view over the whole town. Honestly, Mae Hong Son is a fair way from Pai, so it suits people set on riding the loop or staying a night there rather than a casual day trip out and back. Read our Mae Hong Son guide before planning.
After a full day riding the mountain roads, nothing beats a soak in a hot spring — and Pai has two to choose from. Tha Pai Hot Spring is about 8 kilometres from town, a hot spring inside a national park with a scalding pool hot enough to boil eggs and warmer pools you can ease into. Sai Ngam (a hot spring in the forest) is further into the woods to the north, a clear warm stream running through a bamboo grove — wilder and quieter.
Both are best in the cool of morning or evening, when a soak leaves you loose and relaxed. Sai Ngam is on the same road as Tham Lod Cave, so you can do the two together. Honestly, the cool season is when soaking is at its best, the chill air against the warm water just right.
