Haft-Kul (Seven Lakes, Marguzor Lakes) refers to a spectacular 20km chain of pools strung along the western edge of the Fan Mountains. The first lake is an astonishing azure blue, the next four are aquamarine and the sixth is a pale turquoise. And the final lake needs to be seen to be believed. Six of the lakes are just about accessible (albeit along minimal tracks) by 4WD, but the final lake (Hazor Chashma) is most enjoyable reached on two legs, despite a vague track that suggests that locals manage to coax four wheels up to the water's edge.
Just 63km from Penjikent, Haft-Kul makes for one of the most easily accessible and satisfying excursions from the city, but with a couple of nights spent in nearby homestays, they could easily become the focus of much longer trekking routes.
