DAY USE ONLY. Restrictive parking. Sapphire St. and some parts of Almond St. city parking permits required. No parking in adjacent neighborhood. Trail
skirts the closed Sapphire canyon, stay on trail and obey all signage to avoid legal issues. There are patrols.
Make sure to stretch you calves before this one, the initial climb is a killer for the cold muscles. Paved road for about the first mile then becomes a dry and dusty fire road. Lots of ups and downs on a rocky and loose terrain. Very little cover and gets quite warm in the summer months. There are no water sources except the stream itself. I've never seen the stream dry but, make sure to bring enough water for a round trip.
The trail skirts around the Sapphire Falls Canyon which is closed. Stick to the trail and do not follow the stream south. Steep fines can result if you're caught. There are active vehicular and mounted patrols.
Though parts are currently marked as administration only (probably for vehicles), westbound you can connect to The Barrett-Stoddard Truck Trail
to Mt. Baldy road. You can also branch off and run to the top of 4,085 ft. Frankish peak for a panoramic view of the Inland Empire and as far as Catalina Island on clear days. Eastbound you can run Big Tree/Cucamonga Truck Trail
1N34 and link up with the Cucamonga Peak Trail #7W04
or, continue all the way to Lytle Creek.
