In the last few years many World Tour and Pro-Continental Teams chose the region around La Nucia (Costa Blanca) for their training camps during the european winter. No wonder as it has really nice roads, climbs and 325 sunny days per year.
La Nucia is just 10km away from Callossa, from where you have many choices for training routes. Also Tudons (a climb up to 1000m altitude, starting from sea level) is easy to reach.
The next town Altea has a nice old town and the famous waterfalls 'fonts de l'Algar' are just 15min by car.
