Soppong

Northern Thai market village among karst hills, known for Tham Lot and Shan hilltribe culture.

Soppong (also called Pang Mapha) is a small traditional market village on the road between Pai and Mae Hong Son in northern Thailand. It sits at 750 metres elevation on a small river, surrounded by forested karst hills. Residents are mostly Shan and hilltribe people, and it sees far fewer tourists than nearby Pai while offering more natural attractions.

The main draw is Tham Lot, one of the largest river caves in Thailand — a 1,666-metre cavern with three huge chambers, ancient teak coffins, and massive stalactite formations, navigated partly by bamboo raft. The nightly spectacle of millions of cave swifts returning to roost while bats simultaneously pour out to feed is alone worth the trip. Further into the hills are Spirit Cave, an important archaeological site, and Tham Mae Lana, one of Southeast Asia's longest cave systems for those wanting a real adventure.

The village market on Tuesdays draws hilltribe people from the surrounding hills. Several guesthouses along the river organize village treks and caving trips. The Soppong River Inn has been running responsible tourism here for years. The area is genuinely off the beaten track compared to Mae Hong Son — a good base for a few days of outdoor exploration.

Bars and Cafes

The Seven Elephants Cafe, at the Soppong River Inn 150 metres west of the market on the main road to Mae Hong Son, offers indoor and outdoor seating in a garden of palms and heliconias. The menu ranges across Southeast Asia, with local Shan dishes alongside Western options, and there's a proper espresso machine — a welcome change from the instant Nescafe found at most upcountry stops. House cocktails include the Bloody Mali and the Thaijito, a mojito made with Similan rum, plus a short list of imported red wines.

Drinks, snacks, and Thai or Western breakfast are served on the deck overlooking the river, with music playing through the day and into the evening.

Getting There

Most people begin the trip to Soppong from Chiang Mai. One option is to fly to Mae Hong Son and continue overland from there: the flight takes about 25 minutes and costs around US$20, and once you land you can rent a 4WD at the airport, take the public bus (roughly two hours, about 35 baht), or arrange a private pickup (around 1,200 baht) or minivan (around 1,500 baht) on to Soppong.

Driving yourself is the most flexible option, letting you stop at sights along the way and travel at your own pace. The road is good throughout, and the trip takes about three hours direct from Chiang Mai — longer with stops, which are worth making. Follow signs for "Pangmapha" rather than "Soppong" along the way, since that's the name used on most road signs and kilometre posts.

The bus is the cheapest option but the slowest: a ticket costs around 100 baht, but most services are non-air-conditioned and the trip takes around six hours, with stops in Mae Malai, Mae Sae, and Pai along the way. A handful of air-conditioned buses also run the route, at a similar price, though without a fixed schedule.

Things to Do

Soppong is small enough to walk around in twenty minutes, but the surrounding area in Pang Mapha district is full of cave systems, hilltribe villages, and jungle trails that can keep you busy for days. Tham Lot, the large river cave about 9km north, is the main attraction and worth the trip on its own. The area has some of the best caving in northern Thailand, and guides for both the show caves and more adventurous exploration are available in the village.

When to Go

Soppong sits at 750 metres elevation, which makes it noticeably cooler than the lowland Thai cities — a relief in the hot season and genuinely cold in winter (December to February). The dry season from November to May is the best time to visit: trails are passable, caves are accessible (not flooded), and the air is clear.

The wet season (June to October) brings heavy rain, particularly July and August. The rivers flood and some caves become inaccessible or dangerous. Trails to hilltribe villages can be muddy and difficult. That said, the jungle is lush and beautiful, and there are fewer tourists.

December and January are the coolest months, sometimes dropping below 10°C at night — bring warm clothing if you're visiting then. The light and clear skies in November and February are particularly good for photography in the hills.
