I think Winter is the best time to visit the Canary Islands. It is great to get away from the cold British weather to the mild Canarian climate. This time we stayed in Lanzarote and also visited Fuerteventura. From our resort in Puerto Del Carmen it was easy to take the public bus to all the major towns on the island. It was a real tonic at this time of year https://turismolanzarote.com/en/
