The Sentry Bluff Trail is a 3.2-mile loop. While komoot estimates it takes about 1 hour and 18 minutes, the varied and demanding terrain, including water crossings and steep sections, often means hikers take more time to complete it.
Despite being rated 'easy' by komoot, the Sentry Bluff Trail is considered challenging due to its rugged terrain, steep slopes, and river crossings. It's described as the toughest and longest trail at Bell Smith Springs. While enjoyable for hikers of all ages, beginners should be prepared for a demanding hike and wear sturdy, waterproof footwear. Staying on the marked path is crucial due to common poison ivy off-trail.
The trail features varied and often rugged terrain. You can expect water crossings, steep rocky slopes, and sections that may require scrambling, especially when muddy. There are two river crossings with potentially slippery stones, and the path includes significant elevation changes, sometimes running along sheer cliff edges. Sandstone glades and barrens can also make sections muddy and difficult.
The trail offers diverse scenery and notable landmarks. Highlights include beautiful river views of Bay Creek, a wide variety of wildflowers, and impressive geological formations. A major feature is the 125-foot natural sandstone bridge, offering expansive canyon views from its top. You'll also encounter Boulder Falls, a seasonal 30-foot waterfall, and the unique rock formation known as the Devil's Backbone. Don't miss the CCC Stone Staircase, a historical element from the 1930s.
