Main trail easy, partly paved; top overlook requires steep effort; not fully accessible

The main trail is fairly easy for most hikers, but reaching the bridge requires a short, steep switchback. The round-trip distance is about 2.5 miles (4 km), with some routes closer to 3 miles depending on where you start from the trailhead. This climb can be challenging for very young children, so plan accordingly. Bears are active in the area, especially in early summer when trout spawn in Bridge Creek; hike in groups of three or more, make noise, and carry bear spray.
