The Peter Skene Ogden Trail is a hidden gem. Although it is not widely known among the hiking community, it is designated a National Recreation Trail (NRT) because it “represents its region, supports a diverse community, and is among America’s best trails,” this hike is worth a visit. You’ll hike along Paulina Creek, passing numerous waterfalls, and arrive at Newberry Volcano’s caldera at the end. The volcano is the largest in the Cascades arc, still active, and a smidgen smaller than the size of Rhode Island. This hike has a lot going on!
