    This spot delivers serious fun for families and water sports enthusiasts alike. The Rhum Runner aqua park obstacle course gets rave reviews from kids and adults, with groups ranging from young children to teenagers spending hours laughing and playing. For those interested in wakeboarding, instructor Topher earns consistent praise for getting beginners up and riding quickly, sometimes hitting ramps after just a few sessions. The cable system in the lagoon offers a unique way to learn without a boat. Beyond the water activities, visitors love the laid-back atmosphere with hammocks, corn hole, food from Bongo's beer garden, and impressive murals by street artists throughout the property. The place is pet-friendly and attracts both locals and tourists who keep coming back. Staff generally receive high marks for being friendly and attentive, though a couple reviews mention less-than-stellar customer service at the front desk and bar. The vibe skews casual and relaxed, and families particularly appreciate that it works for a wide age range, making it a solid choice for mixed groups looking for active outdoor fun in the Keys.
