The west trailhead and parking lot at Alderfer/Three Sisters Park will be closed from May through January 2026 while Jefferson County Open Space makes a series of trailhead and trail improvements.

The east trailhead and its parking lot will be open, and parking will also be available at Wilmot Elementary School during non-school hours.

Jeffco plans to expand the west trailhead parking lot, replace and upgrade the existing restroom and kiosk, add picnic shelters and improve Bluebird Meadow and Wild Iris trails.
