Went blind on this trail looking for a challenging ride out of William Heise campgrounds. Very tough climb lots of melon sized rocks, couple of fallen trees along the way.
This trail is probably hardly ridden or hiked. No foot prints, no sign of any activity on the trail what so ever!
Had a blast, very tough, remote, beautiful, for biking this definitely black diamond.
Bring lot's of water!

This trail is the museum of geology.

Hiked this yesterday. I did not find it spectacular or worth the drive to Julian from San Diego. I saw only 1 other hiker and it was on a Sunday so it is not very popular.

Awesome beauty BUT cactus spines and dogs don’t go together.

Great ride for a newbie or just wanting some quick fun . I wanted to break my new Jeep in somewhere not too far away and this was perfect . Some soft sand but nothing big

My first hike with the HikeMania group out of San Diego. Great group of people. Beautiful fall day. You can still see the ravages of the fire 10 years ago, but the vegetation is growing back. All Trails has the mileage and elevation change wrong. The actual mileage is 12.1 miles for the out and back route.

Beautiful colors on the canyon walls. Check out the branching slot canyon about halfway up for a great view across the plateau.

Difficult hike with very little shade. Park at the convenience store, but ask for permission because the parking spots are labeled as customer only. Once you have parked, you will be crossing the street and walking down the road about 50 ft to get to the trailhead (dirt road with fenced in properties on either side of it).

The trail is accessible by off-road vehicles so the paths are wide. However, there are some areas where it is difficult to determine which direction is correct due to lack of signage. Follow the GPS on here and you should be okay. Trail should only be done by experienced hikers/runners, expect to spend 4-7 hours out there depending on your speed. Bring at least 3 liters of water.

One source of water towards the end of the hike about 14 miles in (if you started on the western side of the loop first) it is a natural spring run off made for a local farm. It is recommended you filter it regardless.

Good basic 4 wheel drive trail One tiny rough spot otherwise soft sand and basic hill. Tight walls and excellent camping. Opens nicely to a larger wash that you can follow a ways and pick the highway up again.

We started this hike at Cuyamaca Lake, hiking to William Heise Park. To do that, we took two cars, left one at William Heise and the other at Lake Cuyamaca. The signs say it's 5.5 miles, but that's to the park's boundary. It's about another 1.5 miles to the parking lot from the boundary. It's a beautiful hike, somewhat challenging with the elevation gains and losses. We went in April and there were lots of wild flowers. The view at the highest point is gorgeous, looking to the west and seeing El Capitan Mountain and Cuyamaca Peak. I think if it had been a clear day we could have seen the ocean. Definitely worthwhile!

A nice hike through a narrow canyon with many geological features. There were many people there when we hiked it! The "trail" is a jeep road which gets quite a bit of traffic. A nice walk from the road or drive a mile to the canyon opening. Went in the fall, spring would be best due to lack of greenery.

Long and hard!

Did this as an overnight backpack from Lake Cuyamaca and it was good, coming back the second day was a good climb out of William Heise park. Trail says 5.5 mi. but it felt longer!

I've made this trip quite a few times. Will probably go again thanksgiving weekend. It's a blast. Fairly easy with a non modified 4x4 as long as you take it easy in some of the rougher parts. The mud caves are one of my favorite parts, I can spend hours going in and out of all the little sections. There are some high points you can climb to, and get a pretty good view around. Highly recommended for a family trip to the desert. Also Aqua Caliente is nearby if you want to hit the hot springs.

Awesome trip to take for a day off road. Its a wash type off road with a few rock gardens, need some ground clearance for the first rock garden.. Love the mud caves and explored in some of them which was amazing. Bring a headlamp if you plan to do any exploring!
