I'd passed through Tenerife a couple of times on my way to and from La Palma, and I'd seen the peak of Teide from 90 miles away at the Roque. I finally got to stay on the island when there was a scientific meeting there that I needed to attend. I made my way to La Laguna, in the north of the island, and spent three days there. Most of the time it was misty and cold. It had been 23°C in the south but La Laguna was uphill and inland.
