ITINERARY: Island Discovery Day Trip

Isablea Island National Park is 39 nautical miles from San Blas (but just 10 miles off the Nayarit coast). You may see dolphins, Manta rays or other sea life on your 2 1/2-hour boat trip. From November to April you may see humpback whales.

We arrive early for a day full of activities. A hike to the island's northern point takes you through the interior where you will see the alkaline crater lake. Interpretive signage along the nature trails provides information about the island's flora and fauna. See the Magnificent Frigate birds nesting in the low-laying vegetation, and observe the Blue and Brown-footed Boobies in their courtship dance.

The main building on the island is a marine research center for scientists who study for extended periods on the island. Researchers are often available for lectures.

The Island Discovery Day Trip includes snorkeling and snorkeling equipment. In this preserve you will see tropical fish, yellowtail, grouper, red snapper, jack caravel, eel, anemones and corals in a pristine habitat.
