This trail is almost completely covered by Oak trees, and is most likely the reason many call it Sherwood Forest. It's some of the prettiest terrain in SoCal. There's a lot of shade, a lot of green, and the soil stays dark and moist when most places are dry as a bone. The bottom part of Marshall Canyon
, which this trail covers, is relatively flat so don't look for much of a climb until deeper into the canyon.
Within a quarter of a mile, a wide trail splits uphill to the right, but don't go that way. It twists and rises to a residential street above. Immediately after that, look for a thin singletrack on the right that rises and snakes through the forest for a few dozen yards, bypassing the 6-inch deep creek-crossing you would otherwise have to take... or if it's hot, feel free to get wet like everyone else does.
In a shaded clearing, you'll pass a small horse stable on the right. After a few more creek-crossings, the path rises to emerge from the trees along a golf course. Stay on the dirt and try to avoid using the cart path. The trail dives back into the forest and soon dips into a crossing where it splits, right and left. I always climb on the right, leaving the funner left branch for DH.
