Khorugh

Mountains. Just climb one and you will have spectacular views.

Julandee
towards Murghab High altitude, hot spring resort, and wonderful climb behind the springs. The rooms are quite nice and very affordable. USD 10-15ish. Food is available, but ideally you should bring along some bread, potatoes, and carrots. They will cook, but they have trouble getting the food up there. Very good spot to spend the night before proceeding to Murghab... high enough altitude to see if you get sick. Much easier to evacuate from.
Vanj valley
is spectacular. If you can get a good vehicle... go to the top. There is a glacier calving into the valley. The village up there Poy Mazur will gladly put you up as a guest. Give them a gift... $10-15 and INSIST, as the villagers are very poor.
Garm Chashma
towards Ishkashim -- hot spring and resort like area.

Hop in a marshrutka and get out at a random village. They will put you up, no questions asked. They will feed you, etc. Just bring a bit of money $10-15 to cover their food costs and to help them out. Make sure you insist. For cultural reasons, they will refuse at first, but it's culturally legitimate for you to insist.
