Vancouver, WA: Round Lake

Get a quick outdoor fix without the long drive on this 3-mile loop that circles a small lake, visits two waterfalls, and offers dazzling spring, summer and fall colors.
Publish date:

One of the great things about the Portland/Vancouver area is the abundance of urban and suburban parks offering the chance of quick escape without a long drive. Several locations will immerse visitors in dense woodland, replete with gurgling streams and waterfalls, shady old growth, and plenty of seasonal color. Lacamas Park, a mere 20 minutes away is just such a place.

Park in the small lot on the east side of Highway 500 across from Lacamas Park, and walk up to the trail board near a picnic area and small playground. Pass both and start on a wide gravel trail through fir forest on the Round Lake trail. The path soon crosses a fish screening apparatus, then traverses a concrete dam. From the dam, there are nice views across Round Lake and down the Lacamas Creek channel, pocked and gouged by ancient floods. Stick to the path along the lake to a junction and veer right, staying along and above the creek bed. At the next junction, veer right again along a fenced area with views below to Pothole Falls and more pocked and terraced creekbed. Follow the fence to the end, and keeping right to take the rough trail over mossy lava outcrop. After a short exposed area, the trail dips into wooded cover of maple and hemlock.

After a half mile, the trail meets a wide bridge over Lacamas Creek. Cross the bridge only for views of the gouged creekbed and Lower Falls below, but do not continue to the other side. Instead, stay on the east side of the creek, fork up to the left, away from the creek on old forest road for 100 yards to a trail marked "Access Road" climbing up to the left. The trail climbs to meet another old forest road where you'll turn left and meander under shady trees back toward Round Lake. If visiting in early spring, take the side Lily Loop trail on the right for a pretty display of blue camas lilies; or if water runoff is high, take the short spur to the left to 50' Woodburn Falls.

Back at Round Lake, keep to the right through a couple more trail junctions to complete the loop around the lake. A small platform along the way offers views across the lake. Continue around to the north end of the lake where the trail diverts away, then ends at paved sidewalk. Turn left to the end of the block at Highway 500, then another left back the parking area and your starting point.
