Mountain lake in Crestline at 4,500 feet with a swim beach, water slide, paddleboats, and pine-shaded trails — a true IE alpine playground.

Lake Gregory is a 120-acre mountain lake set in the pine forests of Crestline, 4,500 feet above the IE valley floor. The regional park has a swim beach, a big waterslide, paddleboats, kayaks, a fishing dock, and a 2.5-mile shoreline trail. The cooler temperatures make it one of the IE's most popular summer escapes.
