Yakima River Delta

The Sacagawea Heritage Trail, a bike path traveling through all three cities in the Tri-Cities, crosses the delta alongside State Route 240.

A small portion of extends to the north of I-182 between Queensgate Drive and the Bypass Highway toward the site of the Duportail Bridge.

[1] To the north of the river west of State Route 240 is the 276-acre (112 ha) Chamna Natural Preserve, which is owned by the city but jointly maintained by the Tapteal Greenway.

The preserve is home to 11 miles (18 km) of hiking trails with interpretive signage to provide visitors with descriptions of the plants and wildlife that can be found within its boundaries.
