We took ABC Tours' half-day Jeep Safari to the Natural Pool and Indian Cave, a shorter option than their full-day tours so you can still do something else with the rest of your day. The jeep itself, a proper Land Cruiser, is genuinely comfortable, built with suspension that soaks up the bumps so the off-road ride never feels rough even though the terrain gets seriously rocky. You can technically walk into Arikok National Park on your own, but reaching the Natural Pool, or Dos Playa Beach, really does need a 4x4 and an experienced guide who knows the terrain. The Natural Pool itself is stunning, a genuine must-do, and we brought snorkel gear to swim right there among the rocks. Our tip: book the morning tour, it comes with a really good homemade lunch, we're still thinking about the barbecue chicken, while the afternoon tour skips the meal entirely.
