Sutherland Lake via Black Canyon Road is a 11 mile moderately trafficked out and back trail located near Ramona, CA that features a lake and is rated as moderate. The trail offers a number of activity options and is accessible from March until October.
Start where the pavement ends on Black Canyon road in Ramona and head North about 5 miles, hang a right at the bridge and follow the road about a mile up to the dam. I saw two cars, three hikers and about a dozen mountain bikes so it's not crowded. I found easy but long, about 12 mile round trip.
