Located in Burbank, the Vital Link Trail is in Wildwood Canyon Park, just passed downtown Burbank. A shorter trail, close to 5 miles if you wander up to the radio towers, the Vital Link Trail is great incline training for your legs. Although its mostly exposed to the sun, this trail is a perfect if you're short on time. There are some great places to sit and read at the top if you have the time, so bring a book and some snacks! I even found a communal hiker journal at the peak, under a tree.
