We are going on a trip to the Canary Islands and we would not like to miss accessing the Mount Teide summit, but:
Access to the summit itself is restricted; a free permit is required to climb the last 200 m (660 ft). Numbers are normally restricted to 200 per day.
Reservations can be done on the Teide National Park web site. Problem is, it shows no vacancies left at the time we are going. Without any hope, I have emailed the park so that they let us know of last-minute cancellations.
Are you aware of any other way to access the summit without permit?
