Red Valley

It has fewer tourists, but is just as fascinating. There is no need to book a guided tour because it is easy to find and explore. If you come down Rainbow Mountain, turn left (after about 200 meters you can see the tracks from the viewpoint). You will come to a junction guarded by locals. The left trail will cost you S/10, while the right trail costs S/5. Climb to the viewpoint (5,038 m above sea level) where you can see Rainbow Mountain and the mountain range on one side and the Red Valley on the other. In addition, it is possible to descend another 200 meters to get a closer view of the red valley. There are 2 options to return to the trail/bus. The first and easiest/fastest option is to go back from the viewpoint to the main trail, second to keep to the other side of the mountain range and follow a less touristy route. You will be asked for an additional S/5 for this trail. It is recommended that you follow a guidebook, as the trail is not always easy to identify. As an approximation, just keep to the right of the mountain (you will have to go around the mountain range to get back to the bus station).
