Ruins is a reef break on the west coast of Puerto Rico that picks up NW winter swells, producing intermediate-level waves over a rock/reef bottom. The spot gets its name from nearby historic ruins, and offers a less crowded alternative to the main Rincon breaks. ESE trade winds blow offshore, creating clean conditions during the winter swell season.
