Most of the fun to be had here is either on or below the surface of the water. The most popular activity on Los Roques is to take a day trip to one of the nearby uninhabited cays. If your hotel doesn't include excursions to the outer islands and cays, you can hire a peñero (small boat) at the main docks for between BsF15 and BsF65 ($7-$30/£3.40-£15) per person, depending on the distance to the cay chosen and the number of people in your party. You should pack a lunch, bring plenty of drinks, and try to secure a beach umbrella for shade. Make sure you firmly arrange a pickup time and place for your return to Gran Roque.
