Gate-Belmore Trail Opens in Thurston County

The Gate-Belmore Trail has officially opened, offering residents and visitors a new route for walking, biking, and running in Thurston County.

 

This trail, converted from a historic railroad line, aims to connect over 50 miles of regional trails, enhancing outdoor recreation options.

 

Access to the trail begins at the trailhead located at 14698 Mima Road SW in Olympia.

 

The initial phase spans 2.7 miles near the Glacial Heritage Preserve, linking Tumwater's urban trail system to the southern parts of the county.

 

Once fully completed, the trail will extend 14.5 miles, traversing prairies, wetlands, and forests to reach the Black River-Mima Prairie Glacial Heritage Preserve and the Black River Natural Area just south of Littlerock.

 

The project follows the original railroad grade to minimize environmental impact and preserve the natural character of the land.

 

Before construction, the area was overrun by invasive species like Scotch broom and knapweed.

 

These were removed, and native grasses and wildflowers were planted to support local wildlife, including pollinators, birds, and reptiles.

 

Since the project's inception, species such as western bluebirds, California quail, turkey vultures, osprey, and alligator lizards have returned to the area.

 

Construction was timed to minimize impact on native species, including the federally threatened Taylor's checkerspot butterfly, which relies on native prairie plants for survival.

 

A parking area was installed at a former pit site to avoid new excavation, and efforts were made to protect mature trees by minimizing tree removal and keeping stormwater ponds and access roads small.

 

Future phases of the Gate-Belmore Trail will extend the trail north to Littlerock and include a bridge over the Black River, forming part of a regional network connecting Tumwater to the southern county.

 

The county acknowledges the cultural significance of the land, once home to indigenous communities, and plans to preserve the trail to honor that history.
