My experience there has been that of beholding nature and wealth; feeling them close. It is an island some minutes away from Puerto Cabello, which you can reach by "peñero". Those who want to really invest their time and have not enough money as to travel to expensive locations such as Margarita, Los Roques or Puerto La Cruz MUST come here.
The finesse of the sand makes it the perfect exfoliant for your skin. Being in Isla Larga is nothing more than relax. Take your refreshers, your beers, your woman or your man and enjoy the cristaline water, the sight of fish. Make it a time for love ... or lust.
If you have a yacht, anchor it there. The open sea allows for snorkeling and other subaquatic activities.
Actually, there are some places in which you'll be able to scoff at fish and other sea animals. There is a small restaurant on one side of the island shore. Though, it is advisable that you take your food and drinks with you at the moment of leaving for the Island.
