Following the Trisuli River north out of Kathmandu, we travel through Trasuli Bazaar and Dhunche to Syabrubensi, a Sherpa village located at the very edge of the Langtang National Park. We then swing east into the Langtang valley, crossing the river several times as we travel up along a gorge-like, lower section of the valley. We pass through oak and rhododendron forests and even cross glacial moraine on our way to the Tamang village of Langtang.

A little further up the valley is Kyangin Gompa, where we stop overnight and sample the local yak cheese. We pass through Nubamatang, nestled in a hidden valley, on our way up to view the glaciers, which mark the gateway into Tibet. Backtracking, we travel through Syabru and Sing Gompa to a high plateau, where the sacred lake Gosainkund is located. Crossing the Llaurebena Pass (4610m), we continue south, leaving the Langtang region behind us as we travel through the Helambu valley to Gul Bhanjyang. From here it's just a few days trek back to Kathmandu.
