If you want a proper Bhutan trek that’s both challenging and culturally rich, but don’t quite have the time (or legs) for the epic Snowman Trek, I usually recommend the Laya-Gasa Trek. It’s a trek that mixes high-altitude adventure with real cultural immersion, and it takes you into some of the most untouched corners of Bhutan.

The trek starts near Paro and heads north into the high Himalayas. As you go the landscapes constantly change from meadows to forests, with incredible peaks around every corner. Almost all treks in Bhutan are quiet, but the sense of isolation on the Laya-Gasa really sets it apart. You're far from any other tourists, and even local villages are few and far between.

One of my favourite parts was walking through Laya, a village where the locals still wear traditional dress – their striking pointed hats make them easy to spot.

You’ll cover around 215 kms (134 miles) over 14–17 days, depending on your pace. Expect long days on tough terrain, with some sections going up to 22 km. The highest point, Sinche La, sits at 5,000m, and the climb to it is a real test, especially when the weather turns cold and the wind picks up. The days start with steep ascents to high passes, then descend into remote valleys where you camp for the night. You’ll be trekking at altitude, and the physical demands are constant. But the reward is worth it: stunning panoramas of the Himalayan peaks, and the sense that you’re truly walking in one of the most unspoiled places on Earth.

There’s something incredibly special about the views here. At one point, just before Laya, I stood atop a ridge and looked down at the Masagang range. The sight was unreal, especially with the early morning sun lighting up the peaks. But the real test of the trek comes at Sinche La. The climb is steep and tough, and the weather can change in an instant – snow, rain, or a biting wind. When you finally make it to the top, the feeling of accomplishment is unmatched. The views of the Gangchhenta range and Table Mountain are some of the best I’ve seen.

Need to know

This trek is for those who want a serious challenge. The terrain is rough, and you’ll be camping in some pretty wild locations – alpine meadows, next to glacial rivers, and sometimes in the shadow of snow-capped peaks. There are no lodges along the way, just simple campsites set up by your trekking team. Meals will be included and you can expect local dishes such as yak meat curry, simple vegetable stews and rice.

Acclimatisation and rest days absolutely must be built into the route, with rest days in places like Lingshi and Chebisa, where you can take things slower and adjust to the altitude. Along the way, you’ll meet the friendly locals who are known for their yak herding and vibrant culture.

When to go

While it’s a tough trek, it’s doable with the right preparation. I’d recommend going in the autumn (late September to mid-October) for the best weather – clear skies, stable temperatures, and fewer chances of snow at the higher passes. Spring is doable, though lingering snow can make the high passes more difficult. If you go in late October, you’ll catch the Royal Highland Festival in Laya – a cultural celebration showcasing the unique traditions of the nomadic highland communities and the beauty of the Gasa region.

The right gear is essential too. You’ll need a high-quality sleeping bag, warm layers, and boots that can handle wet, rocky conditions.

When you reach the end of the trek, don’t rush off. Take a dip in the Gasa hot springs if you’re in the mood for some relaxation – it’s the perfect way to unwind after days of tough trekking. Or, if you’re looking to shorten the trek, there’s an option to helicopter out from Laya.
