This hill is the site of San Blas' original colonial settlement. It's worth visiting for the views and to stroll around the ruins of the 18th-century Spanish fort, where colonial riches were once amassed and counted before being shipped off to Mexico City or the Philippines. The place is still guarded by a collection of corroded cannons. On the way up are the gorgeous ruins of the settlement's church, Templo de la Virgen del Rosario, built in 1769.
