The popular Singalila Ridge Trek from Sandakphu to Phalut passes through the scenic Singalila National Park and offers fantastic views of the Himalaya. Guides (about ₹800 per day) are mandatory within the park (the park entrance is near Tumling) and can be hired privately through the GTA Tourist Reception Centre, travel agencies or at the trek’s starting point in Mane Bhanjhang, 26km from Darjeeling. You’re more likely to get a good guide if you line it up beforehand.
