Gahai Lake Wetland Trail

The Gahai Lake Wetland Trail follows lakeside and grassland tracks in the Gahai-Zecha National Nature Reserve, Luqu County, Gannan Tibetan Autonomous Prefecture, Gansu, China. The lake plateau sits at about 3,400 m, and the address is Gahai Town. Trailhead access is alongside the G213 road between Hezuo and Langmusi, with shared cars or buses from Hezuo taking about 1 hour. Parking is informal beside the road and the lake, and visitors should confirm at the reserve whether an entrance fee applies. The trail covers about 3-6 km of lakeside and grassland tracks and takes 1.5-3 hours at a gentle pace. Elevation gain is negligible because the paths are flat, so technical difficulty is very low, but the high altitude can cause breathlessness and headaches for those arriving directly from low ground. Surfaces are packed dirt, grass and boggy patches near the water, and wetland sections may be soft or flooded after rain. Exposure is high, with open sky, strong sun and little shade, and weather can change quickly from clear to cold rain. Key landmarks include the lake itself, the surrounding wetland and grassland, and viewpoints along the shore where waterbirds gather in summer. Gahai is regarded as a good bird-watching stop in the warmer months, so binoculars are useful. A sensible turn-around is any point along the shore, since the flat terrain allows a return on the same track without any commitment to a loop. Water is not available along the route, so at least 2 litres should be carried. There are no huts on the trail, though small shops and roadside stops near the main road may sell tea and snacks. Visitors should stay on tracks to protect nesting areas, avoid disturbing wildlife and take all rubbish with them. The lake works well as a half-day walk on the road between Hezuo and Langmusi, and it can be combined with a stop at Langmusi on the same day.
