A 7.6 mile out-and-back in the southwestern portion of Malibu Creek State Park. This area is drastically different than the areas along Malibu Creek, and offers great opportunities for rock climbing and scrambling, mountain biking, and just plain enjoying some ocean views on a clear day. This particular route features a walk along the Castro Crest, then a descent along Bulldog Road for some elevation gain and loss – although it is possible to extend this route in either direction, or form a large loop hike.

During one of our recent hot and sunny December weekends, my old Mount Whitney Team agreed to show me some of their favorite parts of Southwestern Malibu Creek State Park, a section of that park that I hadn’t yet explored. I was expecting your standard Santa Monica Mountains terrain – a few rocky outcroppings, low brush, maybe a shaded canyon or two – and this area certainly also features all of those things … but there are also stretches of trail here that will make you feel like you’re exploring a secluded rocky canyon in Utah. That is, until you look up and see the Pacific Ocean in front of you.

This route starts out at the end of Corral Canyon Road – the same road you’d take to hike Solstice Canyon. For this hike, drive past Solstice and through a few small “villages” of Malibu cliff-houses until the road dead-ends in a dirt parking lot. From here ,you can hop on the Backbone Trail in either direction, start climbing up the Castro Crest, or explore the Mesa Peak Fire Road Trail.

From the lot, look toward the east for an unmarked fire-break heading toward some large rocky pinnacles. This is the Backbone Trail, and it’s the first path you’ll start hiking on.

This path follows the ridge 0.5 miles east along some wonderful stretches of granite and sedimentary rock – similar to the formations around Sandstone Peak, but a bit more warped and weathered. In fact, you’ll see quite a bit on this 4/10ths of a mile – including some fun simple scrambles, fantastic views of the Pacific, and an old wreck of a car that seems cemented into the dirt. Don’t feel bad about taking your time to explore.

There is also a wonderfully wavy section of rock here that features a small but easily accessible stone arch. If you don’t mind getting your hands a little dirty (and you shouldn’t – you’re a hiker!), a very quick scramble will get you inside the arch itself.

When you’re done pretending you’re in a very outdoorsy episode of Laugh-In, head east down a short, steep slope and rejoin the Mesa Peak Motorway – a fire road that’s part of the Backbone Trail system. When we were climbing down, we came across a group of people taking their RC jeeps along the rocks, which was very unexpected. With a little tilt-shift photography, you could probably shoot a great Jeep commercial up here …

From the junction with the fire road, you can continue east to Mesa Peak (1884 ft) in about 2.9 miles one-way. We chose not to – both due to time restraints and the fact that the peak is actually lower than the fire road you’re on … but even if you’re not headed to Mesa Peak I highly recommend continuing east about another 0.15 miles.

Here, on the north side of the trail, you’ll see another large rock formation and piece of hiker-art on the ground – a stone spiral.

I don’t know how long this spiral’s been going, but apparently it has grown since the last time my hiking companions were there. If you’re feeling creative, feel free to add a few rocks to the outline to keep the spiral going. If you’re not, the rocky area behind the spiral has a lot of attractions, too – there are several small caves to explore and squeeze through, and some great, easy scrambling routes to the top as well. Be sure to budget some extra exploration-time for this area.

When you’re done, either tackle the route to Mesa Peak or head back west along the Backbone Trail to the parking area where you began. I took the Fire Road back to Corral Canyon Road, which is not necessary – but it does provide some interesting views south into the Malibu Bowl, including the foundations of an old burned down house in the canyon.

Back at the trailhead, look for the sign for the Castro Motorway at the north end of the lot. From here, it’s 0.8 miles to the Bulldog Motorway, and the trail gains over 400 feet in that distance. It’s not necessarily steep, even by Santa Monica Mountains standards, but it’s the first big elevation push on this route, so be ready for it.

There are a few use-trails and unmarked spurs on both this stretch of fire road and the Bulldog Road ahead of you – for this first stretch on the Castro Peak Motorway, just remember to keep heading up and west, and skip the two side routes.

When this fire road hops to the north side of the Castro Crest, you’ll get some incredible views of Malibu Creek State Park below you. If you’ve been hiking along the creek itself, this view puts the park in an entirely new perspective – and will most likely give you a unique appreciation for the area’s geography.

After 0.8 miles on the Castro Peak Motorway, you’ll come to a clear junction with the Bulldog Road. Castro Peak lies covered in radio towers ahead of you on its namesake fire road, but the summit itself is gated and unreachable on private land. Instead, take a right onto Bulldog Road here.

Although Bulldog Road is a fire road, it may be a bit steeper than other fire roads you’ve hiked before. In 2.5 miles, the road loses more than 1100 feet of elevation along several hairpin turns. While the trail scenery here may not be much to write home about, you will definitely have more than your fill of incredible views of Malibu Creek along the way:

Again, there are several construction roads, spur roads, and use trails along this section of the Bulldog Road. Make sure you consult the map to make sure you’re staying on the Bulldog Road and not taking a side-route into a dead end.

This path down the Bulldog Road is mostly exposed, although it does have a few shaded areas as you get to the lower elevations. The path also crosses a noticeably cooler canyon with a seasonal creek bed. The turnaround point on this route was arbitrary, although you can continue another 1.4 miles down the Bulldog Road to the M*A*S*H site along Malibu Creek. When you’re done, return back to the trailhead the way you came in … and take your time. The uphill on Bulldog Road isn’t overwhelmingly steep, but it IS relentless.
