Local Insider Tips for Your Trip

Unbeatable Strategic Location: Staying in Mar de Cristal or Playa Honda puts you just 5 minutes from Calblanque's wild beaches, 5 minutes from Cabo de Palos diving, and right on the warmest family-friendly waters of the Mar Menor.

Afternoon Paddleboarding: The sheltered bay of Mar de Cristal remains virtually wave-free; late afternoon is ideal for renting a SUP board to explore the tranquil shoreline.

Dining in Los Belones: Just 1.5 km inland, the village of Los Belones boasts over 20 exceptional international and traditional restaurants, making it the culinary nightlife hub of the southern lagoon.

Pack Water Shoes for Exploration: While the bathing areas have fine soft sand, wearing water shoes is helpful when exploring rocky edges and natural reed sections near the salt pans.
