In the leafy Colonia Escalón neighborhood, 'Volcano Summit' offers popular dorm rooms downstairs and four color-themed private rooms on the 2nd floor. The communal lounge is large and quiet, and the shared kitchen and terrace are ideal for meeting other independent travelers. It's within walking distance of some of San Salvador's best restaurants.
There's a second Cumbres del Volcán hostel in the Flor Blanca neighborhood.
