Windy Gap Trail, Mountain trail in Angeles National Forest, California.

Windy Gap Trail begins at the uppermost parking lot of the Crystal Lake Recreation Area, about 3 miles up from State Route 39 above Azusa. It climbs due north up the steep canyon face above the campground, crosses the South Hawkins fire lookout access road twice, and reaches the Windy Gap saddle at 7,588 feet (2,313 m). The hike is about 2 miles and links to routes for Little Jimmy Trail Camp, Mount Islip, South Hawkins and Baden-Powell.

The Curve Fire of September 2002 burned 20,857 acres, including parts of the Crystal Lake Recreation Area and stretches of the Windy Gap Trail. Nearly the whole route was left exposed to direct sunlight, and new growth appeared during the trail restoration that followed the fire.

The trail intersects with paths leading to numerous destinations including Little Jimmy Trail Camp, Mount Islip, and Baden-Powell, creating a network for outdoor exploration.

The hike begins at Crystal Lake Campground and involves steady uphill climbing throughout the route. Proper footwear is essential since the path has steep sections and uneven terrain.

Strong air currents flow through the Windy Gap saddle, creating natural cooling relief during the climb. These persistent winds give the spot its name and become especially noticeable during warm afternoons.
