In reply to Lorraine McCall:
update on climbing Teide.
Lots of people leave about 1 in the morning to climb to summit and wait for sunrise. If you are not booked into the refuge then this is a popular way to do it. It seems to be around 5-6 hours from the refuge route car park depending on how you handle alititude..
I opted for the Parador route. I left at 12 15 and planned to be at the telefrique station for 5 ready to climb to summit for sunset. En route up I met some people who had taken a morning cable car and just walked to the summit with no hassle from the guards. I arrived at the telefrique station just before 1600 (the last hour I was quite slow due to altitude). The guards were rounding people up for the last cable cars at 5 so I was a bit conspicuous and did not think it would be easy to sneak to the top.. Being on my own and a bit of a wimp I decided not to carry on doing the last 200mtres as to wait until sunset would have meant coming down in the dark and the trail was a little trickier than I had thought. (very straight forward in daylight).
I walked and ran back down doing the last hour in the dark. The sunset was spectacular, it would be amazing to be at the top for it and I will go back the next time I am there now I know what to expect. It took 2 and a half hours to come down. I am not fast but pretty steady.
Whether you do the summit or not it is a great walk. It does not cost anything to get a permit but you have to apply in advance to the Teide National Park.
Hope this is helpful.
