hi Fortyplus
Well I can't help you with Sky TV it does have cable but this setting has everything you need for activities you suggest nearby. The resort would be able to help you book but it is not right there as per Centre parcs.
The Resort is situated 20 minutes drive away from the coast and one of the cleanest beaches in Spain is only 10Km away. The Mar Menor saltwater lagoon is the largest in Europe and has waters 3C warmer on average than the Med. Water sports for all the family can be arranged around the Lagoon.
Water sports available including diving, Jet skiing, windsurfing and sailing. There is also waterparks nearby and quadbiking.
All along the coast, from Cabo de Palos and Portman to Cartagena or Mazarron, the National Park of Calnegre or Cabo Cope, there exist numerous possibilities for going hiking. In the inland areas you can arrange hiking, pony-trekking, mountain-biking, mountaineering, rock-climbing, trekking and rafting.
Various specialised companies organise day-long activities which can be enjoyed in the heart of the countryside, on land, at sea or in the air, provide: potholing routes through caves of exceptional interest, horse-riding, rural activities, white-water canoeing, cave-diving, deep-sea diving, paragliding, hang-gliding.
A lot of cut and paste going on here to give you a fuller picture of the region. Found this site which is the tourist info for the region. Let us know if you find somewhere. Defo need a car in this region.
