Ask local people if there is one nearby, i.e. in Husseini. You'll meet and talk with locals, see costumes, traditions, taste some traditional food and take part in traditional dancing - all in a backdrop of magnificent mountains and Hunza River.
Access is from the town of Husseini, where a road traverses up the hillside. There is a campground and restaurant by the lake and you can swim in it during summer. If you continue on the road passed the lake you eventually get to the start of a trail that leads up the side of the Passu glacier offering perhaps the best views of the area
A footbridge constructed from cables and wooden planks that crosses the wide Hunza river. There is a path that leaves the Karakoram highway at the first hairpin as you head south from Passu. A circular walk can be created by crossing the Husseini suspension bridge further downstream.
The valley is located between the Passu and Batura glaciers, and behind Zard Sar (the peak immediately above Passu). The trail is marked by cairns and stays to the right of the lake below the Passu glacier.
