Fortaleza de San Fernando in Omoa, Honduras, is an impressive 18th-century Spanish colonial fortress, easily accessible by road and located directly on the Caribbean coast. Visitors can explore the site independently, though a guided tour is highly recommended to fully appreciate its rich history and strategic significance, including its role as the last Spanish stronghold in Central America. The fortress is generally open year-round, with the dry season (December-April) offering more comfortable weather for exploration, which involves walking on uneven surfaces and stairs. A typical visit lasts 1-2 hours, and the approximate cost for entry is low, usually a few US dollars. Practical tips include bringing sun protection and water, especially as the site is largely open-air and often combined with a visit to the nearby Omoa beach.
