8. The remarkable caves of Patal Bhubaneshwar, which have rock formations worshipped as gods, remain largely unexplored. Stalactite and stalagmite formations, and striations on the ground give the impression that the entire cave rests on the back of Sheshnag. The main cave is 105m long with an 85-step descent. Some passages are extremely narrow, requiring you to squat. Guides are available. It is 91km from Pithoragarh. You can stay at KMVN resthouse at Bagnath (011-23712296, www.kmvn.org).
9. Over the last 50 years, the old colonial resort of Nainital has suffered more than its share of retribution for the inequities of Empire. But as the second city of Uttaranchal, it deserves a second look for the considerable charms that survive. For all the clamour of the mall, the lake is still sheltered by thickly forested slopes, where Raj-era decorum (and décor) still prevails at two royal retreats now open to the public. The Palace Belvedere (seat of the Rajas of Awagarh) has doubles (011-2626650-55, www.welcomheritage.com) and views of the lake, while the grander Balrampur House sits amidst sprawling lawns (05942-236236, 011-23384495).
10. For a man after whom the highest mountain in the world is named, George Everest, the first Surveyor General of India, didn&rsquot get very far&mdashwell, he got up to Hathipaon, on a small hillock (known as the Hathipaon Hill) near Mussoorie, on the edges of the Himalayan range where the last bit of the Great Arc survey was completed. &lsquoHathipaon House&rsquo, as it is now known, was his house and laboratory. Its crumbling remains still stand. It&rsquos worth a visit, even if you are not a cartography fan. Hathipaon is 6km from Mussoorie.
11. The Narayanswami Ashram, established in 1936 (17km from Tawaghat, at an altitude of 3,017m), looks like a small alpine castle set in the middle of fir trees and a beautiful garden. The building is apparently an old British bungalow, over 100 years old. It&rsquos also close to the Askot Sanctuary. Yoga classes are held at the Ashram. Another ashram worth visiting is the Mayawati Ashram located 22km from Champawat and 9km from Lohaghat, at an altitude of 1,940m. The ashram is situated in the middle of a secluded old tea estate.
