Pros & cons
PROS
- Front-row vantage of the Skagit hydro project and Ross Dam engineering.
- Quick access gateway to the Big Beaver backcountry trail network.
CONS
- All the climbing is packed into the return from the dam.
- Limited parking at the MP 134 pullout fills early.
Small pullout at milepost 134 on State Route 20; limited spaces and often full—arrive early.
Steep, sustained climb on return; uneven tread with rocks/roots. Sections beyond the dam can be narrow with steep drop-offs. Strong winds possible on the dam. SR 20 may close in winter; check conditions. Treat all water before drinking.
Overview
This is a quick hit with a payoff: a 1.5-mile total out-and-back that drops from State Route 20 to the rim of Ross Lake and the top of Ross Dam. Expect roughly 500 feet of elevation change—most of it you’ll feel on the way back up. It’s rated moderate, but the steady climb on the return can surprise casual hikers.
What You’ll See
The path descends through forest, crosses Happy Creek on a bridge, and pops out to broad views of Ross Lake and the massive concrete face of Ross Dam—part of the Skagit River Hydroelectric Project. On clear days from the overlook area, some hikers note sightlines to Colonial Creek Falls across the valley. You’ll also pass a small waterfall along the way and get those classic teal-water lake vistas.
Trail Character
The tread is uneven singletrack with rocks and roots and a sustained grade; not stroller-friendly. Portions beyond the dam can narrow with steep drop-offs—watch your footing if you continue. Plan on about 45–60 minutes round trip if you’re just visiting the dam and returning.
Best Time to Hike
June through August typically offer the clearest path and best views. Shoulder seasons can bring snow or ice, and SR 20 near here can close in winter—always check conditions before you go. Early starts help with limited parking and softer light over the lake.
Connections and Extensions
From the dam, hikers commonly continue into the Ross Lake network, including access to the Big Beaver Trail for longer day hikes or backpacks. Some visitors coordinate water taxi pickups along the lake for one-way itineraries. If you’re camping along Ross Lake, expect to secure reservations/permits in advance. All natural water must be treated before drinking.
Pets and Practical Notes
Leashed dogs are allowed here within Ross Lake National Recreation Area, but pet rules tighten quickly in the broader National Park Complex—mind boundary signs. Wind can rip across the dam deck; layers help. Trekking poles make the climb back to the highway easier.
Getting There
Trailhead is at milepost 134 on State Route 20 with a small, often-full pullout. Start early or have a backup plan.
