What is Bijli Mahadev and why is it significant?

Bijli Mahadev is a Shiva temple perched on a rocky summit at 8,070 ft above Kullu town, accessible by a 3 km stone-paved path or by the road from Chansari village. The temple is famous throughout Himachal Pradesh for a specific phenomenon: the temple's trident (trishul) is regularly struck by lightning (bijli) during monsoon storms. The legend holds that the Shivling inside the temple absorbs the lightning strike each time, shattering into pieces — after which the priest rebuilds the Shivling from butter and flour before the next strike. The temple has one of the finest panoramic views of the Kullu valley — a 180-degree view of the Beas river sweeping through the valley below, with the Rohtang-Paralkar peaks at the north end. It is a major pilgrimage destination for the Kullu valley communities.

How is the forest walk route structured between Bijli Mahadev and Naggar?

The route descends from Bijli Mahadev (8,070 ft) to the Beas valley floor (4,000-4,500 ft), then crosses to the right bank and follows the forest ridge northward through several mid-altitude forest belts before reaching Naggar (5,774 ft). The walk is not a high-altitude ridge but a forest corridor traverse — relatively gentle on altitude but covering significant ground (28 km over 2 walking days). The local path network through the right-bank forest is known to Kullu valley guides and some shepherd families — it is not marked and not found on hiking maps.

Is Kareri Lake a natural lake?

Yes, it is a freshwater high-altitude lake fed by the snow-melt from the Dhauladhar range.

Where do we start the trek?

The trek starts from Ghera village, about 20km from Dharamshala/McLeodganj.
