The Ross Dam Trail is an out-and-back hike, typically ranging from 1.6 to 2.2 miles roundtrip. It's generally considered a moderate trail. While the initial descent to the dam is relatively easy, the return journey involves ascending approximately 500 to 700 feet, which can be challenging. Expect rocky sections and potentially loose rock.
The trailhead for the Ross Dam Trail is located off Highway 20 in the Ross Lake National Recreation Area. There is a designated parking area available at the trailhead. Since the trail is accessible before the gate closure on Highway 20, it's generally accessible year-round.
The trail takes you through evergreen forests with trickling creeks and waterfalls. You'll pass Happy Creek Falls around 0.27 miles in and the unique Snapping Turtle Rock. As you descend, enjoy 'window views' of alpine mountains and the turquoise Ross Lake. At the dam, you're rewarded with expansive views of Ross Lake, the Skagit River, and peaks like Colonial Peak and Pyramid Peak.
Yes, dogs are permitted on the Ross Dam Trail. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors.
No, there are no entrance fees or permits required to hike the Ross Dam Trail itself. It is located within the Ross Lake National Recreation Area, which does not charge an entrance fee. However, always check the official NPS website for any updates on regulations or conditions.
The Ross Dam Trail is accessible year-round because it's located before the gate closure on Highway 20. However, for the most pleasant hiking conditions and best views, late spring through early fall (May to October) is generally recommended. During winter, be prepared for snow and ice, especially on the descent.
The Ross Dam itself is a significant engineering marvel, completed in 1948. It's 1,300 feet long and drops 540 feet to the Skagit River below. Walking across this massive concrete structure offers unique views and a sense of its immense scale. It's part of the Skagit River Hydroelectric Project.
Yes, the Ross Dam Trail serves as an access point to the broader network of trails within the Ross Lake National Recreation Area. From the dam, you can connect to other routes like the Big Beaver Trail, which leads to beaver dams and ancient cedars further along Ross Lake's western shore.
The trail can be suitable for families, especially those with older children or those accustomed to hiking. The initial descent is manageable, but the uphill return journey requires some stamina. Be mindful of rocky and potentially slippery sections. The unique features like Snapping Turtle Rock and the dam itself can be engaging for kids.
Even though it's a relatively short hike, it's wise to pack essentials. Bring plenty of water, especially for the uphill return. Wear sturdy hiking shoes with good grip due to rocky and potentially loose terrain. Layers of clothing are recommended as conditions can change, and consider sun protection for exposed areas on the dam. Snacks, a first-aid kit, and a map are also good to have.
The main safety consideration is the uphill climb on the return journey, which can be strenuous. Watch your footing on rocky and potentially slippery sections, especially during wet conditions. While much of the trail is shaded, the dam itself is exposed, so be prepared for sun exposure. Always be aware of your surroundings and any wildlife.
