A great English-speaking tour company
Although you would find many tour companies in San Pedro, the quality of the tours differs. Not all speak good enough English to explain in detail the geography, history etc. I tried two tour companies and am recommending the better one - Cosmo Andino Expediciones (On Caracoles Street, just across from more famous but somewhat disappointing Desert Adventures). Cosmo is not the cheapest, but I thought the difference was worth it for the quality. Although all tour companies may go to the same place, e.g. Valle de Luna, the geysers, your experience really depends on the itinerary. It could be a boring point A to B bus tour (like my bunk-mate's), or it could be like my Valle de Luna tour. Cosmo got us to walk two long stretches through the desert and canyon on our own (1+1 hours total) and it was a UNFORGETTABLE experience. I also took a El Tatio geyser tour with COSMO and had casually asked if I could borrow a jacket at the time of signing up. The staff, Veronica remembered, even though it was two days later. I really appreciated the jacket because El Tatio was freezing in the morning. Kudos to a wonderful tour company! The canyon walk. I don't know the name of the canyon as it was part of the tour I took with COSMO. But it was amazing walking through it and listening to the salt columns in the mountain expand and contract. I sat down and journal-ed because it was simply too magical.
A little of everything
Is necessary something comfortable not like a expensive bag or something because the town is really rustic and everything can get dirty. Different kind of clothes because during the day is hot and sunny so you will need a t-shirt and shorts or light pants, during the afternoon is necessary a sweater and during night you will need a lot of clothes because is cold.
Take a swimsuit because you can go to the thermal baths or even take a bath in the river.
Comfortable shoes, to be able to walk a lot and to climb. Take some wet little towels to refresh, aspirins and of course something for the stomachache.
The sun will be shining all the time so take a good sunblock. There is also the possibility to camp in the town so take all necessary. Don't forget that there is not electricity after midnight so is useful a lantern.
Sandboard is a great experience not just because of the place but because of feelings when you are going down in dunes of 120 mt, is really exciting.
this experience is lived in the death valley and the price of the tour includes expert guide, transportation and equipment.
The cost is around 17 dollars.
Is important to take sunblock and water.
Spending the afternoon in prehistoric times
Nevertheless, the astonishing beauty of El Tatio mutates and turns into an almost extraterrestrial way as the day goes by: in the morning, as the Sun rises, the steam plumes recede and things begin to look flatter, the bright light and silence makes one feel at another planet, while the only sound is that of the almost invisible steam rising from the fumaroles. Then, in the afternoon, when the sunlight falls from a lower angle, shapes and textures arise to life, as well as the first mists from the streams of hot water coming out of the ground; the sky turns into a deep indigo, and the Tatio volcano gets redder every passing minute. I had the luck of spotting a lenticular cloud right above the volcano’s cone, which turned into a bizarre deep red by the end of the day, while the geysers began to rise again into the chilly, sub-zero air.
Then comes the wind, and the night falls.

Vallee de la Luna
Some 10 km away from San Pedro, Valle de los muertos y Vallee de la Luna should not be missed.
The best is to rent a bike in San Pedro to visit them, although you have to do it early in the morning (because of the heat and the wind). If you want to see the vallee de la luna at sunset many agencies organize tours, but I recommend you find other people to go on a "private" tour if you want to avoid the crowd (up to 150 people ...).
