The Claremont Wilderness Trail is a gateway to adventure and other, more rugged trails, one of which eventually ascends Mt. Baldy. However, the section most popular with sports enthusiasts is roughly 5-miles, fairly balanced in terms of uphill and downhill stretches. A popular spot for hikes and mountain biking, a lot of people also bring their dogs, but some don't come prepared to ensure their pets don't get heat illness or dehydrated.
Parking: The lot closest to the trailhead gets full early, fortunately, there's another a short distance down the street, however. Be sure to pay and display your parking permit, however, the Rangers are usually on patrol. Once situated, it's time to hike or ride.
There's a "dogleg" common approach trail after passing through the gate and at the 'wishbone' you can decide your approach the Right-Hand path is probably steeper going up, but has slightly more shade on the lower section. The Left-hand path is more exposed but has gentler steep sections. Either way you'll get to the covered gazebo at the summit. There's an outhouse up there too, just in case...
I saw one Coyote but this is nature and Mountain Lions and Coyotes live here, they look for opportunities, especially foolish people who let their dogs off the leash. Speaking of foolish people, we witnessed two poor dogs whose masters failed to bring any water for themselves, mush less their pets. It was well into the high 80s by mid-morning and the dusty rocks in the trail were heating up. That plus little shade and the wretched animals were flopping down in the small patches of shade and refused to go on. Lesson here is bring water and a collapsible water bowl.
Overall, the hike is moderate to difficult depending on your fitness level. Good trail shoes or light hiking boots are recommended, and a small day pack could carry additional fluids. In warmer months I'd say start by 8am, but naturally, if you arrive at 7am when the park opens, that'd be even better.
