It's followed by a descent on the backside of the peak, which then leads into a very narrow singletrack along a canyon wall.
Need To Know
Parking at Toro Park has a fee, though you're allowed to park on the dirt areas outside of the park as long as there is space.
There are 3 small dry creeks (less than 1 foot wide) to cross during the descent that are not optional and require hike-a-bike or jumping.
The trail starts in Toro Park near various picnic grounds, then slowly switches to fire roads and singletrack, leading up to Ollason Peak at 1800'. This is a fairly long and tiring climb.
The reward for the climb is a long technical downhill along a canyon wall. The difficulty comes mostly from the narrowness of the trail, with the canyon lurking below (10-20 feet) and the tight turns.
There are various other trails here that can be combined. After the descent, you can turn left at the main road to repeat the loop.
