San Juan del Sur ’s main show is the brightly colored day’s end over the languid harbor waves; San Juan sunsets can go on for hours; make sure you’re on the beach or a sunset cruise  as the setting sun drapes the fishing boats in shadow and the rock face of El Indio dims behind the evening. But there’s a lot to do before day’s end—take a hike , go sailing or diving , or find the area’s best surf breaks .
Next to the Casa de Cultura on the main beach drag are volleyball and soccer facilities; league games on weeknights. During the rest of the day, the Sports Park is open for (often competitive) pickup games. Otherwise, expect soccer games to be played on the hard sand beach at low tide on either end of the bay.
