We might have saved this one for the 4th of July, but we're Trailblazers and ahead of the pack.
This is a gorgeous hike that requires just enough effort to make it interesting. We start at the end of Liberty Canyon Rd. in Calabassas and quickly join the mysterious Phantom Trail. The Phantom rises like a spirit up onto the western ridge of Liberty Canyon and opens up to panoramic views. Most of our elevation gain will be spent getting up to the ridge, then it's a cruise.
Two miles later, we descend to and across Mulholland Highway and into Malibu Creek State park, where we splash down in Century Lake. We'll take our ease in the shade at Century Lake before scooting along Crags Rd. (the well-traveled access road in MCSP) to the aptly-named Grasslands Trail. A short climb later, we'll traverse Mulholland again and skip through grassy fields singing happy songs until we reach the Liberty Canyon Trail, at which point we'll weep openly and gnash our teeth.
Just kidding! Those with the energy will still skip and sing, while the sane ones among us will simply walk out to where our adventure started. This is a loop hike that roughly parallels Las Virgenes Rd.
The journey will be a tad over 7 miles, with about 1100' of elevation gain- 800 of it expended getting up onto the ridge near the beginning of the hike. Some of the trail is covered (overgrown, perhaps), while much of it is open- prepare accordingly. *After pre-hiking, my suggestion is to wear long pants for the initial portion of the hike, though you may want zip-offs for later.
From 101, exit Liberty Canyon Rd in Calabasas. Take road south (toward the ocean) less than a mile and park near the end of the road.
*Note: Liberty Canyon Rd. appears to make a sharp left, but the road name changes at that point. The trailhead is behind the black metal gate at that sharp turn. You can park along the road leading up to the turn or in the dirt pull-off about 40 yards before the gate.
