Wees Bar Petroglyphs Trail

The trail begins by crossing the Swan Falls Dam. You can typically find parking near the dam, which serves as the trailhead for this route.

While the trail is generally accessible, it's important to consider the challenging terrain, lack of shade, and potential for snakes. If you bring your dog, ensure they are on a leash, well-hydrated, and prepared for a strenuous, rocky, and potentially hot journey. Always check local regulations for the Morley Nelson Snake River Birds of Prey National Conservation Area regarding pets.

Spring is often recommended for jogging this trail, as you can avoid the intense summer heat due to the complete lack of shade. Spring also offers the best opportunities for spotting raptors during their mating season. Be aware that the trail can be wet during this time. Avoid the peak summer months due to extreme temperatures.

The Wees Bar Petroglyphs Trail is located within the Morley Nelson Snake River Birds of Prey National Conservation Area. Generally, there are no specific permits or entrance fees required for day use of the trail itself. However, it's always wise to check the official Bureau of Land Management (BLM) website for the most current regulations and any potential changes before your visit.

The terrain is varied and challenging. It largely follows a jeep trail and a rocky road alongside the Snake River. You'll encounter sections of dirt singletrack, 'braided' paths, and areas with 'melon gravel boulders' – remnants of ancient floods. There's also an ascent of about 300 vertical feet on a rocky road. Expect it to be a 'hard run' where you'll 'work for it'.

The primary draw is the exceptional collection of ancient Wees Bar Petroglyphs, found on dozens of massive boulders. Other notable features include crossing the historic Swan Falls Dam at the start, the former site of the Priest Ranch Homestead with its orchard remnants, and the ruins of the Wees Bar Stone House. You'll also enjoy expansive views of the Snake River canyon and distant Owyhee Mountains.

The trail is within the Morley Nelson Snake River Birds of Prey National Conservation Area, renowned for its raptor population. You have a good chance of spotting hawks, eagles, and falcons, especially during the spring mating season. Be mindful that you might also encounter snakes along the path.

Given the trail's difficulty, lack of shade, and potential for heat, wear appropriate jogging attire, sturdy trail shoes, and bring plenty of water. Sun protection like a hat, sunglasses, and sunscreen is essential. During spring, be prepared for potentially wet conditions. Consider bringing a map or GPS device as sections can be 'braided'.

This is a 12-mile out-and-back route. You will return along the same path you took to reach the petroglyphs.

The Wees Bar Petroglyphs are an exceptional collection of ancient rock art, believed to be created by the ancestors of the Nez Perce and Shoshone tribes between 800 and 10,000 years ago. Their remote location has contributed to their excellent preservation, allowing visitors to see hundreds of well-preserved carvings depicting humans, animals, and geometric designs.

The conservation area is dedicated to protecting one of the densest nesting populations of raptors in North America. When visiting, stay on marked trails to protect sensitive habitats, observe wildlife from a distance, and pack out all trash. Respect the historical significance of sites like the petroglyphs by not touching or disturbing them. Always check the BLM website for specific rules and advisories.
