We booked two trips: the biking tour and the beach-baobab combo. The former trip was amazing. Perfect way to visit the island. The bikes are comfortable, the pace is relaxing and we learned a lot from our wonderful guide.
The visit to the beach was also good but we preferred the bike tour. The beach is very clean although do not expect big waves, the ocean is very shallow near the shore. There is an option to swim in a nearby lagoon but we definitely preferred the ocean.
