This is a well-maintained fire road that is a smooth, steady climb. The trail starts behind the Doctor's House at Brand Park. At the top, you can look down both sides of the mountain into La Crescenta-Montrose and Glendale.
Begin your ride on the paved road up and past the Doctor's house and then make a left onto the Brand Park Motorway paved road. This turns into a pretty steep climb and then eventually the road ends and the trail begins. You do have to lift the bike over a yellow fence/gate that is always closed.
My friend and I have been only mountain biking a few months, but this killed our legs/energy levels. From there, it pretty much turned into a hike up the trail while we pushed our bikes up.
You have to have the lightest bike and calves the size of tree trunks or a giant grandma gear to climb this one... it took us over an hour and a half on foot to get up and only 15 minutes to get down. Once you are at the top, it connects with Verdugo Motorway
or you can turn around and head back down the way you came.
The trail itself is pretty wide, but there are some chunky rock sections and recent rockslides that narrow the path a bit. It's fast and a bit wind-y so you'll be working your brakes pretty good depending on your tires. There may be the occasional hiker on their way up, too, that you have to watch out for.
