La Palma - Canarias
La Palma, Canarias is one of the best destinations to be in winter if you are living in Europe. There is a tight trail network and some mountain bike specific providers which show you the best trails on the island. The essence of La Palma is that it has so many trails with different terrain, climate zones and difficulty levels in such a small place. If you want to ride with one of the shuttle and guiding providers you might stay in Puerto Naos or in Los Llanos de Aridane. If you do some self guided XC tours without using shuttle services than El Paso (however there is no night live) might be an option to.
