The main reason that pushes me to go to Tenerife.

1) The cable car that will take you to Rambleta at 3555 meters above sea level, therefore approximately 200 meters from the summit.  From there it is necessary to continue on foot and a special permit is required, which is free, and it is advisable to request it at least three months in advance as there are only two hundred places available.

The starting point of the cable car (in Spanish teleferico):  Carretera TF-21, km 43 - Teide National Park.

2) Walk up path number 7, skirting the Montaňa Blanca. The climb takes at least 5 and a half hours. Arriving before nine in the morning, therefore leaving at night, there is the possibility of climbing to the top without permission, as the control points open at that time; but it's just hearsay.

My personal experience: I went to the cable car departure twice but in both cases the lift was stopped due to strong winds. In any case, we are talking about a high mountain environment and therefore the weather conditions are quite extreme.

My suggestion is to use every possible day, any window of good weather to try to climb to the top. Last piece of advice: it involves climbing to almost 4000 meters and even though you are coming from sunny beaches you absolutely need to dress appropriately. On my last trip I learned from television that around seventy people who had boarded the cable car had had to be rescued, risking hypothermia due to their summer clothes.
