Despite its nondescript name and facade, the interior of the Hidden Art Gallery is an expansive space. The gallery currently has over 400 pieces of art, representing more than 50 artists in its 3,000 square feet of wall space. Fourteen rooms are coordinated by style, but the main attraction is the permanent exhibit of resident-artist Carlos Hiller and his underwater images. The gallery also specializes in local art and features new exhibits from emerging and established artists each month. Located 5 kms south of the Liberia International Airport, this gallery is a must-visit for art lovers in the Guardia, Guanacaste area.
