It's often interesting to delve into differing beliefs. A trip to Iglesia El Calvario is a good way to get to know one of the local religions and cultures.
When you've spent a bit of time at this Chinandega house of prayer, why not make your way to Museo Chorotega-Nicarao, Santa Ana Parish, and Guadalupe Church? They're not very far from Iglesia El Calvario and also a favorite with many tourists.
