Rainbow Falls State Park

Highlights

A tranquil Chehalis River camp with just enough trail, easy Willapa Hills access, and a polished forest atmosphere that makes short rides feel especially lovely.

Riding

Within the park itself, the trail mileage is modest—about three miles through hillside forest—but the bigger attraction is the spur connection to the Willapa Hills Trail. That pairing lets you choose either a shorter, more relaxed park ride or a longer rail-trail outing with real point-to-point appeal.

Rideable terrain

3 miles

Trailer parking

Use the park road system and trail-side parking areas with the equestrian campsites as the most rider-friendly overnight base.

Horse regulations

Horse use follows designated park and trail access only, and state-park rules apply throughout the campground. Riders tackling the Willapa connection should also check current trail conditions because some segments of the corridor remain under development or seasonally affected.

Getting here

Arrival is straightforward by state-park standards, and that matters. You are not puzzling through a giant forest road system or improvising a dispersed-camp setup. The equestrian sites make the logistics more intentional, and the park's campground services keep the whole stay comfortable.

Planning your visit

This is a smart stop for a southwest Washington itinerary, especially if you value calm camp atmosphere over maximum trail mileage. Reserve early if you want one of the two equestrian campsites, and check the seasonal campground schedule before hauling.

Where to stay

Rainbow Falls is especially strong for riders who want horse camping without a rough-edged backcountry feel. Showers, restrooms, a kitchen shelter, broad campground amenities, and riverside atmosphere make the overall experience feel organized and welcoming.
