Lonely Planet review
During the dry season, turtles come ashore on the beaches at Ureca to lay their eggs. Since 1996, the Spanish conservation group Los Amigos de Donana has employed villagers as guards to patrol the beaches during nesting season, and the local market for both turtles and eggs has gradually decreased.
Although Ureca is undeservedly lacking in tourist infrastructure, there is a small guesthouse here that makes for a convenient base. When you're not sunning yourself on the beaches or watching the cycle of life unfold, there are excellent opportunities for hiking in the nearby jungle.
