Karian Shola Nature Trek.
Karian Shola is one of the few publicly-accessible primary evergreen rainforest patches inside Anaimalai Tiger Reserve. The trek requires a TNFD escort and prior booking from the Pollachi Divisional Forest Officer's office — most tourists arrive at Topslip without booking and only get the basic departmental safari (1 hour, ₹250). The Karian Shola escorted trek (4 hours, ₹1,500-2,500) takes a maximum of 6 visitors per day; advance booking essential.WHY NOBODY KNOWS
