Stay Safe

In Oregon, a bicycle is legally considered a vehicle, and the same Oregon road laws apply. Please “be seen” and practice safe riding. Vehicle traffic, farm equipment and narrow shoulders exist on many Oregon roads, and you may find that construction projects, traffic or other events may cause road conditions or signage to differ from the map results, ride descriptions and directions. For travel options plus weather and road conditions, visit, call 511 (in Oregon only), 800.977.6368 or 503.588.2941. Routes listed on this website are for informational purposes and intended as a reference guide only.

This small nature park is a delightful springtime stop, and a cool oasis in the summer. A narrow footpath lined with trillium, bleeding-heart, and other wildflowers descends into a ravine with fern-covered basalt outcrops, then winds up the opposite slope. Dense willows at the bottom are buzzing with Rufous Hummingbird by April. Orange-crowned Warbler and other riparian species can be expected later in the nesting season. Nearby Dalton Lake hosts waterfowl, plus woodpeckers and songbirds in the surrounding woods. Follow a paved trail from the Columbia Humane Society, and hike dirt path leading to a cliff overlook.

Botanical Gardens: In St. Helens from US Hwy 30 near MP 29, turn NE onto Liberty Rd. Go 0.4 mi to junction with West St. then 0.1 mi further. Turn L (NW) on 6th St. for 0.6 mi, and park on R side of road by sign for Columbia Nature Trail. Dalton Lake: Immediately after turning NE onto Liberty Rd from US Hwy 30, turn L on Oregon St and go 0.3 mi to Columbia Humane Society, from which a trail leads to overlook.
