There are two National Parks and three Natural Monuments on the island. You'll be enchanted with La Restinga lagoon, a National Park with an extension of 26,439 acres, the biggest one on the island that has a lagoon of 18 square miles with beautiful canals and mangroves. Margarita is only 9 degrees from the equator. You will notice very little variation in climate between summer and winter. Spanish is the official language of Margarita although English is commonly spoken in the tourist areas.
Currency is the Venezuelan bolivar.
You will need a valid passport for entry to Margarita and you need to be sure that it does not have an expiration date within 6 months of your travel dates.
