Baetis Bend & Lunker Alley Trail Fishing Access Site provides parking and trail access to popular fly-fishing areas on the San Juan River's Quality Water section, located near Frustration Point south of Highway 173.

The site features a Navajo Lake State Park parking area with a pay station and rest rooms (no drinking water), with trails leading north to the river for access to Baetis Bend's slower, wadeable water and Lunker Alley's deep runs.

Most of the Lower Flats area is wadeable except during runoff, making it accessible for wading anglers.
