Fossil Rock, located in the desert near Dubai, is a popular geological site known for its concentration of marine fossils embedded in the rock formations. Accessibility can be challenging, requiring a 4x4 vehicle due to the sandy terrain. While solo exploration is possible for experienced desert drivers, guided tours are recommended for safety and a richer understanding of the area's geology and history. The best time to visit is during the cooler months (October to April) to avoid the extreme heat of the summer. A visit can range from a few hours to a full day, depending on your level of exploration. Costs can vary depending on whether you opt for a guided tour, but expect to pay for transportation and potentially permits or entrance fees if required by local authorities. Be sure to bring plenty of water, sunscreen, and appropriate footwear for hiking in the desert.
