This is a great alpine trail, but getting to start can be the tricky part. Visitors will have to travel by foot from either the Big Tree Trailhead via the Cucamonga Peak Trail
, or start out at the Icehouse Canyon trailhead and take the Icehouse Canyon Trail
just to get to the beginning of this trail. The extra effort will be more that worthwhile, as the views from the summit of Ontario Peak are breathtaking.
As an added bonus, once on the Ontario Peak Trail you immediately enter what truly feels like a wilderness area. Runners will bump into few people and the journey becomes a more solitary activity than a group one. Be sure to slow down and soak up the views, though challengingly steep portions of the trail will check your speed either way.
For the return trip, turn back around and enjoy a well-earned descent.
