Geography
The peninsula is connected to the rest of Isla Margarita by a thin strip of land in
Laguna de la Restinga
Laguna de la Restinga is a national park on the Isla Margarita, Nueva Esparta state, Venezuela.
The main part of the park is a large salt lagoon, rich in fish and birdlife. It is on the Ramsar list of wetlands of international importance, and is ...
National Park. Sixty years ago, it was an island.
The peninsula has an area of , rising from sea level to at the peak of Cerro Macanao.
A ridge of high land runs along the peninsula from east to west. The main east-west crest is sharp and narrow.
The mountains are smaller than in Maragarita, but are much more rugged, with many steep-sided valleys cutting through the mountain sides.
The more remote beaches can only be reached via dirt roads.
The climate of Margarita as a whole is hot and tropical, with little rainfall. The Macanao peninsula is particularly arid and dry. In the 1950s, the mountains in the central range were forested up to about .
Vegetation today is mainly open cactus-chaparral, with deciduous forests in the seasonal riverbeds.
The mean average temperature is , and mean annual rainfall is . Trade winds blow from the northeast, so rainfall is highest on the northern side.

visited in 1799 he was met by eighteen Guayqueria men. He described them as "of very tall stature. They had the appearance of great muscular strength, and the colour of their skins was something between a brown and a copper colour."
As of 1964, the population was about 6,500, living in five hamlets. Water was delivered by barge at no charge, but with only a few liters per capita for all uses.
Tourism
The Macanao peninsula is sparsely populated. Tourists may take horseback rides, or visit picturesque beaches with fishing boats, such as Punta Arenas. The ''La Pared'' beach is pleasant and little used. Divers prefer ''Punta Arenas'' beach at the far west, where the water is warmest and where giant starfish may be found.
Macanao is also the best part of the island for mountain biking for those prepared to handle the intense sun.
The largest town is Boca de Río, which has a marine museum, This includes the skeleton of a whale, displays of boats, fish, corals, pearls and turtles, and a shallow aquarium with

Environmental concerns
Isla Maragarita is the largest of the Venezuelan Caribbean islands, and the most biologically diverse. The only protected area is a small part of Laguna de La Restinga National Park. The proposed Macanao Wildlife Reserve, containing the Chacaracual Community Conservation Area (CCCA), may provide better protection.
Conservation threats include high levels of illegal hunting and trafficking of wildlife and plants, and open cast mining.
The peninsula is the only home of the endangered
