For locals, Garam Chasma is the Pamirs' most popular open-air hot spring. A single pool surrounded by a cascade of calcified deposits is a little reminiscent of Turkey's Pamukkale, albeit in very miniature form. The pool is exactly the right temperature and discreetly cordoned off for (same-sex) naked bathing. The spring is a 20-minute drive southeast of the highway.
The published timing of the sessions alternating for men and women don't quite match the reality but there are a couple of cafes opposite to wait it out if it happens to be the 'wrong time'.
