The most popular activities on Ilhabela involve boating/trekking to far-flung beaches and waterfalls. However there is also diving (two-tank outing R$260 to R$420; try Narwhal), wakeboarding (per hour R$100) and treks to the island's prominent peak, the 1048m-high Pico do Baepi – a 14km return trek that can be done without a guide. Sea kayaking and stand-up paddle (SUP) boarding can also be arranged.
