Allow 15 min by foot to reach the shore below the hotel. The beach, which is in Saint-Aubin, is vast. It extends all along the bay, which is 3 miles. Plenty of width on the sandy part, particularly at low tide, though there are no loungers for rent. This beach is best for jogging or horse riding. The beautiful beach with watersports and loungers and parasols for rent is in Saint-Brelade, 2 miles away.
As for land-based sports, the hotel has a partnership with Les Ormes leisure village (next to the airport, 3 miles away): its tennis courts, 9-hole golf course and fitness room are open to the residents of the Cristina. Ask for more information at the reception regarding opening hours.
