The “Small Galapagos” Island of Nayarit
The 3-million year old volcanic island “Isla Isabel” is known as the “small Galapagos” and is uninhabited except for thousands of marine birds and reptiles who nest there. During different parts of the year 92 species of birds can be found, including extensive colonies of frigatebirds that are always present in some numbers.
In addition to the large variety of bird life there are also 6 species of reptiles, among them the brown iguana (Ctenosaura pectinata) and the Mexican Milk Snake (Lampropeltis triangulum) which is known as a “false coral snake” for its black head with a post-ocular band that is orange, yellow, or white followed by a black band. Both reptiles are in danger of extinction. You’ll have a chance to see the famous green iguanas (Iguana iguana) too.
Isabel Island is one of the principal nesting sites of marine birds in the Pacific Ocean, a unique place with a plethora of life. There are many Frigates, Brown and Blue-footed Boobies, Brown Noddies, Bridled Terns, and Brown Pelicans. You have the opportunity to see numerous red-billed tropicbirds, with beautiful long white tails, along the tall cliffs surrounding Isabel. On the lee side of the island are blue and red footed boobies that are quite interesting to observe during their mating rituals.
This part of the island is also a prime place for snorkeling, one of very few in the Eastern Pacific where are found coral reefs, home for tropical fish. In some 3 feet of water you can see Surgeon Fish, Trumpet Fish Fish, Needle Fish, Eels, Sea Urchins and more. The water is normally clear and warm, offering an excellent visibility. You must bring your own snorkle gear.
It takes about 2 1/2 hours to cross the 42 nautical miles from San Blas to Isla Isabel, so it’s necessary to get an early start from San Blas. Optionally you can stay over night or longer if you bring your own camping gear and carry enough food and water. You must provide your own gear and food.
To set foot on the island requires an authorization issued by the National Commission of Protected Areas (CONANP) and be accompanied by a duly authorized guide.
