David J.

We went on an unguided kayak trip through the mangrove lagoon. It's very reasonably priced and relaxing. Cas Cay is beautiful. Wear water shoes that you can also do some light hiking in (if that's your thing). There's a trail across the island with some beautiful views. ★★★★★

As a group of 4 adult couples with a love of kayaking, we recently booked the self-guided 4-hour tour. The paddle through the mangroves was lovely, and the paddling was easy and enjoyable. The staff were helpful and polite both on our way out and the return. Terry in particular stood out, sharing her recommendations on locations to visit. ★★★★★
