Puerto de la Cruz is lovely. There are dragon trees, which bleed red sap. The beach is made of black basalt so no Chavvy union Jack shorts. The hills are clad in beautiful laurel Forests, home of the rare Bolle's Pigeon. Try the cream cake shop near the bus station, they are superb. The volcanic formations at Parc canadas at the foot of Mount Teide are not to be missed. Also here is an excellent cafe and an interesting visitor centre and museum.
However, if you are going to Los Christianos or Playa de la Americas bad luck - take a good book.
That's OK then. Also don't miss the Botanical gardens: there are tropical trees from all over the world. Unless you are hiring a car, take the bus. You can buy a block ticket that gets you everywhere. They are sold at the information place at the bus station. The buses are clean and efficient and go everywhere.
HAve a lovely time oldspice.I am workng easter sunday, monday and Tuesday!
