Located between Mount Dallas and Cady Mountain on San Juan Island, Mount Grant Preserve protects and provides access to 250 acres of diverse forest, woodlands, and meadows. Visitors to the ridgetop summit are rewarded with sweeping vistas in all directions.
Spring visitors can enjoy pockets of wildflowers and take in the birdsong around the ridgetop, while summer visitors can watch raptors hunting along the ridge and enjoy the breathtaking views.
Trails and roadways to the summit are open daily for pedestrian and nonmotorized use. Driving access to the summit is open as follows:
- April—September: Sundays (weather permitting), 10am–7pm.
- October—March: Sundays (weather permitting), 10am–4pm.
The San Juan County Conservation Land Bank owns and manages the preserve, while the Preservation Trust holds a conservation easement that ensures the “gold standard” of protection, now and for future generations.
