Trekking Permit Details
You need to user the Tenerife.on website or app to book permits but the Pico del Teide may be generally sold out a month in advance. Neither the web or app are intuitive but here are my steps for permits (or any of the restricted areas in Tenerifie). I will focus just on the Teide summit for this discussion, but the same methods apply for other permits. I will also discuss the mobile app even though the web site can also be used.
To get a permit you first must pick the trail(s) in the app. Open the trail to dig deeper and then move down the screen to see a calendar if a permit is required. No calendar = no permit required.
The calendar will show days in green if there are any permits available for that trail. Grey if it is fully sold out. Note that some trails like PNT 10 to the summit from the chair lift lookout may include a lift (one-way or return) option when booking.
Teide summit permits have time slots and the slots around the chair lift operating hours are sold out fast. New permits open every Monday morning at 7am for the next 30 days.
However, midweek, I did find an opening for two people the following day in the afternoon with the lift. I casually started filling in the booking info. When I tried to pay the transaction failed. I kept getting an error and kept trying to re-type my info. Finally, I gave up and restarted the process and found that the slot had been taken.
So, when you see an open slot, the app will not hold it for you while you enter your data and go to pay. Others may also be trying to book that slot. Prepare your data (including ID numbers etc.,) in advance for fast input.
You will also need to purchase associated permits if you descend on foot.
Reaching the Summit of Pico del Teide Specifically
You need to book a permit for PNT 10 (this is the 300m section from the chair lift lookout). You will need to purchase lift tickets with the permit if taking the lift. I recommend a lift to the lookout and a walk back down. Why? Because none of the trails up are doable in a day, in my opinion. There is zero water on the volcano, and you have to gain almost 1,750m in a single day. The distances up are around 12 km minimum. How much water can you carry?
Trails connecting the chair lift lookout area are PNT 09 from the west. This is not recommended if you parked at the lift and then took the lift to the lookout since you need to walk or take a taxi all the way back to the lift base at the end of a long day.
There is a short-cut down from PNT 09 near the first caldera via trail S-28 down to the road TF-38 junction near the Welcome Center, which is closer to the lift car park.
Trail PNT 07 is the same distance as PNT 09 but ends to the east of the lift car park and is not too far away (plus an groomed trail runs along the road back to the lift parking area).
Trail PRT 41 starts/ends at the north coast near Puerto de la Cruz and is 54km long and has a 4,132m altitude gain. This is an impossible ascent and a crazy option for a descent.
Alternate Chair Lift Tickets
In town I did notice billboards and agencies offering lift tickets to the lookout at the base of PNT 10. Some include full day excursions and others include just one-way up or down options. They generally priced the lift tickets at twice the rate of Tenerife.on but seemed to have much more availability. So, if you manage to book a summit permit but can’t get the lift ticket then use one of these agencies.
