Weather is generally good. True bike packing is difficult as officially, wild camping is forbidden. There are lots of official camping spots which don’t charge but you are required to register in advance. It’s to do with knowing who’s sleeping out up there in the forest should a forest fire break out.
Weather is great at this time of year, pretty much hot enough to spend a day on the beach and Mount Teide is absolutely stunning. If you get a chance pop over to La Homers, about an hour by ferry, it’s a very magical little island 🙂
