The route starts from the car park at an altitude of 2,200. It goes around Montania blanca, the shelter Altavisto to Teleferico Del Teide. It seems to me that it is located in the middle of the most demanding section of the road.
Geocache is located on the route between Montania Blanca and shelter Altavisto, at a point which is usually chosen as a place to rest. At several stone boulders. At the route is one characteristic like a ball.
The route from the car park at the top of El Teide was made by us in 3h40min. But while gaining the summit and descent I had severe symptoms of altitude sickness. Therefore, I believe that the way in terms of intensive sun and high altitude which you can easily gain is demanding. I recommend acquiring the top a little longer with multiple stops and acclimatization. We arrived at the car park at 11 and pass on peak for an hour 15, so we had to hurry.
