El Teide from San Cristóbal de La Laguna

Hard easy climb: extreme length. I needed 5+ hours to climb only, starting from Tejina via La Esperanza.
Before leaving, the front derailleur of my rental bike was not shifting to high gear. While fixing I thought: you don't need any 50 in Tenerife! And so it was.
While piercing a nice and shady pine forest with gentle slopes, I could see blue skies and the Ocean all around me, but I was riding in the clouds and freezing cold. Is this Sahara latitude or the Alps??
At 2.150mt I was hoping for the Sun and an oxygen mask to drop on me. Cold headwinds came instead. Weather changed quickly (November) and I was glad I had a winter base layer to put on to descend.
I found the desired Sun and clear skies (I was higher than clouds!) In the final part.
Coming back: I descended to La Orotava and then followed the coast back home. I planned via Climbfinder and roads were Ok! Extra +650mt and excellent landscape added, no flat roads in Tenerife!
Be very careful where you plan roads, as people here are relaxed and used a relaxed approach following the maximum slope line with narrow and straight 25/30％ roads (!) to go from A to B. Why bother with engineering and hairpins?
You will need good brakes if you descend there, I just had calipers but I luckily survived as crossing cars were so kind to stop and leave room for me to pass.
I hope any attempter will enjoy this climb as I did, as it's a unique place with volcano lunar landscape at the end, worth the effort. Winds can be strong in last 7 Km, unfortunately traffic is high but respecting cyclists, tarmac is excellent both sides.
