Lower and Upper Shellburg Falls (100ft) can be found by passing under moss-covered arches lead to an observation deck and a natural cavern is behind the falls. This remote adventure has minimal hikers during spring months.
The hike, including the initial 1.25 mile gravel road to the trailhead, is easy to complete within 1-2 hours and only requires a moderate level of fitness. Snacks and water are recommended.
Being remote, there are very few hikers on the trails most days, so one shouldn't have a problem finding parking or avoiding crowds. There is extra parking space along the roadside if you do arrive at an unusually populated time.
The two unique features of Upper Shellburg Falls (44.81201, -122.60802) are moss covered arches leading to an observation deck at the basin of the falls and a large carved out cavern that runs behind the falls. One should be cautious when walking behind the falls as the ground can be extremely muddy and slick during the winter and early spring seasons. The small bridge at the trailhead gives an impressive lookout at Lower Shellburg Falls and the ravine below. You can also check out Stasel Falls, which is only a short walk past the trail head and down a small trail to the right off the road.
The easiest starting point for Shellburg Falls is via the Shellburg Falls Campground.
