Nice and calm waters with lamas feeding in front of the picturesque mountain ranges. Great for some shots with the camera.

This is the little hill right east of Sajama village. You can see the trail clearly, which goes straight up the hill. But only do it if you are not going to do Mt. Huisalla right next to it north, which has much better views.
Wisalla
This medium-difficult peak provides amazing views of Nevado Sajama, Sajama village and the surrounding plains. Due to the high altitude it can be a day trek, the higher you get, the harder it will become to progress. Take your time! There is a trail that goes almost straight up from the village, or you choose the longer one that circles the mountain to the east and then offers a less exhausting final trek at the end.
Campo Alto
If you want to hit the height but without a guide, try hiking up to the base camp of Nevado Sajama. In winter, the trail might be impassable with regular boots due to snow and ice, but in summer it is definitely possible. Again, take you time and start the descend early enough—it gets dark at 18:00.
A volcano whose peak is the highest point in Bolivia and guided 2-3 day mountain climb with overnighting at the Campo Alto at 5,680 m.
Quite expensive, considering the hot spring along the Salar de Uyuni tour is just Bs. 6. There are other (private) hot springs nearby, try this hot spring or this one. From the latter a trail north leads to two more hot springs, which might be for free.
A little cheaper and free if the lady is not there. So, go early or late (coming from the Tres Lagunas Trail), or just be lucky (e.g. in off-season).
