Castillo del Morro in Santiago de Cuba is a UNESCO World Heritage site offering stunning views of the Caribbean Sea and a glimpse into Cuban colonial history. The fortress is generally accessible, though some areas may have limited mobility access due to the historic nature of the site. Exploring solo allows for flexibility, but a guided tour can provide valuable historical context. There are no significant seasonal restrictions, but the best time to visit is during the dry season (November to April). Expect to spend around 2-3 hours exploring the castle, with an approximate cost of a few CUC for entry. It's advisable to bring water and wear comfortable shoes, as there is some walking involved.
