It's worth a visit, given the azure sea and sky, and the lush vegetation. However, the ferry departs at 9:30 AM, and you arrive on the island close to 11:00 AM, by which time the sun is blazing. If you want to explore at a leisurely pace after hiking, you'll miss the 2:00 PM ferry. Time is a bit tight; I actually think the best time to visit is from afternoon to evening.
