Ilhabela is portuguese for Beautiful Island, and that´s what this island really is. A paradise for people that like to be outdoors. The island is ideal for who want to practice aquatic sports. There are great 35 km of beaches, a coastal Atlantic rain forest, a UNESCO Biosphere Reserve, mountain peaks to climb and over 400 cool waterfalls cascading into the ocean. Add to that legends of pirate treasure, underwater wrecks to explore, great sailing, enough to make Ilhabela's annual Sailing Week a must.
The best time of the year to go there, depends on what you are looking for. In the summer and during weekends the island is a little crowded but not enought to make it impossible to find a place for relax and enjoy the nature, off season or during the week most likely you´ll have the beach to yourself or will share it with a few people. For diving it´s best during the summer, but if you are a sailor you should go during Sailing Week in July when international sailors participates in races and regattas. Since the coast between São Sebastião(a city near Ilhabela) and Rio de Janeiro is popular cruising water, there are numerous facilities for sailors.
This is it friends, I have a video on the previous post about this island, where you can see more of this beautiful place.
