After finding over 30 caches at the time, I decided to hide my own. This cache is about 1 mile round trip assuming you take the right route.
Park at the Tree People parking lot:
Tree People
12601 Mulholland Drive (at Coldwater Canyon)
Beverly Hills, CA 90210
(818) 753-4600
Check out the map near the buildings if you want a better idea of your surroundings. Proceed down the trail to the north of the parking lot. Go east on Oak Trail and then turn left at the junction with Betty Dearing Trail. Take a footpath on your right further up the hill, and then to an even smaller path on your left that leads you to a clearing with a bench. The cache is then very close by.
I spent quite a bit of time setting up the original cache. I was pleased to see it last 9 years, then another 9 or so years, and hopefully further still in its newest incarnation.
For questions, comments, or assistance, feel free to message me and I will respond as soon as I can. I would say that this is a good one for all walks of geocachers. Note that dogs are allowed in the park but must be on a leash. There are also many other trails and caches in the area to explore.
I have made a few other maintenance notes about the cache, which can be found in the logs.
Have fun and good luck! :-D
