Chamna Natural Preserve

Seven interconnected trails along flat terrain parallel the Yakima River. The Chamna Natural Preserve Map is easy to follow if you have a particular trail in mind; otherwise, wander at will as it is pretty hard to get lost between the river and the access road. The west end is mostly dry desert. If on two wheels, watch out for thorns. As you move further east, the desert transitions to wetland and riparian areas. This trail system is part of the Great Washington State Birding Trail Sun and Sage Loop so bring your binoculars and prepare to update your life list.

Amenities
There is a large, gravel parking lot and portable toilets.

Regulations
Richland Parks and Recreation rules and trail etiquette apply.

Wildlife Awareness
We are all so fortunate to recreate in the Blue Mountains and Walla Walla Valley. So many opportunities exist to play outside, whether in a national forest, wilderness area, or on a Wild and Scenic River. With these opportunities comes great responsibility to appreciate that we are mere visitors and should all take pride in being good stewards of the wild.

Many animals call these protected places home, including moose, elk, bear, cougar, bobcat, and snakes to name a few. Take precautions to respect their home and understand the appropriate response should an encounter occur.

Additionally, many plant species thrive in the Blue Mountains, so staying on trail is always good practice.

Carry First Aid supplies to better respond to accidents or encounters, and always let others know where the day’s adventure is taking you.

Field Notes
Navigation: Consider downloading the Avenza Map app. This app allows users to upload three maps (or unlimited with a subscription) to use offline. It can track your location offline and overlay GPS data from the phone onto the map. The vehicle use maps (for trails allowing motorized vehicles) are the easiest to use.

Otherwise, Geo Tracker offers similar tracking capabilities and additional details about your adventure. If no service, Geo Tracker will at least show your location. The Blue Mountains and surrounding area offer a remote recreating experience, and knowing your location is paramount to staying safe. Always make sure to bring paper maps. Tell others where your adventure is taking you and when you expect to return.

Pets: In general, pets are allowed on a leash and under control throughout jurisdictions. The only restrictions we have encountered are around swimming areas. As a best practice, be mindful of riparian habitat in general. You never know where a precious spawning area might be located. Pack it in and pack it out applies to your furry friend as well.
