With its 5 miles of walking distance it's an average length hiking trail. The hiking trail stays roughly within the same elevation zone the whole time which means the conditions are about the same from start to finish. This is a one trailhead hiking trail, so you'll be trekking it in and back out. This backcountry walk shouldn't take more than 4.5 hours, but you never know stuff could go wrong and you could get stuck so be prepared for that. At parts of the year this region sees very little rain, so make sure you check current conditions and fire restrictions with local forest authorities before you head out. Even though this is not a very long hiking and backpacking trail it's always good to bring some emergency supplies, you never know what could happen. Ontario Peak Trail has a total elevation difference of 1,159 feet which is about average.
