Castillo de San Felipe de Lara, located on the shores of Lake Izabal, is a historic Spanish fort offering a glimpse into Guatemala's colonial past. The fort is relatively small and can be explored in about 1-2 hours. A visit is quite affordable, with a low entrance fee. While the grounds are generally accessible, some areas may present challenges for visitors with mobility issues. Exploring independently is common, but a local guide can enrich the experience with historical insights and anecdotes. There are generally no seasonal restrictions, but it's wise to check conditions after heavy rains or storms. It is recommended to bring water and sun protection.
