5. The Story of Neelkanth Mahadev Lake Trek

According to local Lahauli legends, this is where Lord Shiva absorbed the deadly ‘halahala’ poison during Samudra Manthan, turning his throat blue (Neelkanth = blue throat).

Mystical Facts:
🔹 The lake never fully freezes (even at -20°C) – locals believe Shiva’s energy keeps it liquid
🔹 No aquatic life survives in its waters, reinforcing the poison legend
🔹 A small ancient Shiva shrine stands near the lake, where sadhus meditate during summers
🔹 Shepherds report seeing strange blue lights over the lake on full moon nights

Modern Significance:

• Considered one of Lahaul’s most powerful spiritual sites

• Annual puja performed by Keylong priests in August

• Trekkers often report feeling an “eerie calm” near the waters
