Great hike. A bit of a climb so make sure you are ready for the elevation change and the length. Also beware of the trail skips on the southern part of the loop before you get to the Mesa overlook trail shown on the current map. It’s doable you just have to forge your own path, find a different trail or use the road.

A good walk. The first few miles through a wooded valley as the sun came up were very beautiful. Then a long steady climb to the trail along the ridge. The views from the top were wonderful, but it is all along fire roads until near the bottom of the descent. The way back on GPX route from the Backbone trail trailhead was not a path. I walked along Las Virgenes for a short way before heading back into the park.

Awesome views of the ocean once you climb to Casto Peak. The GPX was very confusing at the junction of the Backbone trail parking lot just next to the water treatment facility. Had to hike on the busy road and re-enter the park to find the trail. Lost the trail again (in the dark with headlamps) at the bottom near the campgrounds and had to finish the hike on Malibu SP roads...still agreat day

Beautiful ride as always, but the recent storms have really washed out the rock garden, making it a much tougher trek than usual. The usual "trail" through the rock garden is pretty destroyed, and lots of roots and other debris to contend with. I struggled or even had to walk my bike through a good portion of it that I am normally very comfortable riding through. Unsurprisingly, lots of hikers/walkers to navigate through, and on a weekend most are unfamiliar with trail etiquette, so don't expect anyone to yield to you or otherwise make space. Overall, one of my favorite moderately challenging rides with gorgeous scenery and some fun sections of trail.

The first 3 miles are relatively easy then miles 4-7 just kick you butt with a major incline and 0 shade. Other then the lack of shade it gives you some great views with an overlook of Malibu.

Excellent hike! We got caught in the rain on top, but continued on. Fantastic views on top, easy roads to hike. Trails are clearly marked except on the eastern side of the trail. Map is a bit confusing there, and you have to take some detours to stay on course. Very few people after an hour in. MASH set was an excellent surprise!

Loved it. I went clockwise. The uphill was great, awesome coastal views along the high ridge, pretty gradual downhill on the other side. Sweeping views all around. All in al the trail is moderate but it's long. Most of the trail is sun-exposed and on a fire road.

This is a loop trail...but the map is wrong at the highway part - one does not need to get on the highway in order to get back on the main parking lot.
Mottroad is shown on the map and it should be taken instead of highway but if not careful enough you might miss it; the road adjacent to the right of Mottroad can be taken as well..
Once you reach the highway one only has to cross bridge over that DWP creek then make a left thru a parking lot - cross the parking lot and trail can be seen right away - is gated by wooden beams...

challenging loop. beautiful. IMPORTANT: those below writing that the finish is on the main road, DID NOT find the correct route at the finish to stay on the trail. Hard to find the correct finishing trail but it is there.

Great but the last part is on a busy road which is no fun...would prefer to finish on dirt rather than pavement.

It was the longest and best hike I have done so far.
I did with 4 of my friends and total miles hiked was about 19. We met some of the nicest people and a true gentleman in every way, who helped us when we got to the caves. I honestly didn't think there were any more real good men left in this world. His wife and his mother would be so proud , plus he was VERY HANDSOME !!!
The views were amazing, the cave's were an unexpected surprise.
The 6 mile hike all Up up up up was strenuous but well worth it. What an amazing world we live in.!!!

First time visiting this loop, did it as part of a training run for the Bulldog 25k trail race. Started off at Malibu Creek State Park (mile 0) and went counter clockwise direction on the loop. About 2.3 miles into the run we ran into the MASH site, kinda cool place to visit and take pictures of some of the leftovers from when they filmed the movie and TV series decades ago. Just before mile 3 the trail starts climbing up fairly steeply and doesn't seem to stop until about mile 6. Then it descends for about a mile when it reaches a trailhead parking lot. Good place to stop and take a breather as the trail starts climbing again through some interesting landscape. The rocks make it look like it's some alien landscape but it's Malibu. About 2.5 miles of up and down running we then hit a good descent, a drop of about 1000' in 1.3 miles. We crossed over a small creek and then took a different trail than the one shown here to get back to Malibu Creek State Park, opting to not go on Las Virgenes. Very difficult running for me and probably for a lot of people, but the challenge is worth the scenery. Make sure you bring lots of liquid, especially if you go during the summertime like I did.
