Shadow Cliffs Regional Park

Shadow Cliffs is a regional park with an 80-acre lake surrounded by hiking trails, picnic areas, and a swimming beach. The 266-acre site offers boating, fishing, and various recreational facilities along the shoreline.

The park was created in the 1970s from the site of a former gravel quarry, transforming an industrial area into a public recreation space. This conversion demonstrates how abandoned mining operations can be successfully reclaimed as nature reserves.

Birdwatchers and nature enthusiasts gather regularly to observe ducks, herons, and seasonal migrating birds throughout the year. The lake has become a focal point for wildlife observation and quiet moments spent connecting with nature.

The park is open daily with ample parking near the lake and beach areas. Bring plenty of water and sun protection, as shade can be limited in some spots.

The lake was not formed naturally but created by filling the abandoned gravel pit with water, which defines its shape and depth. This unusual origin makes it an interesting example of how nature can flourish in places humans have transformed.
