About the Hike: Walnut Creek Park (also known as the Michael D. Antonovich Trail) is a very beautiful hike in Los Angeles County that mostly takes you through a shaded oak grove. There is very little elevation except for at the very beginning which is a 300 ft. drop into the canyon.
Be prepared to navigate across multiple creeks which may present a challenge after a good rain. We hopped across the rocks which have been laid out in a row pretty effortlessly. With water shoes you can walk right across the water!
The parking lot starts you off at a scene with beautiful views. It would be a great spot to enjoy the sunset or have a meal with a view as tables are provided. Dogs are allowed but PLEASE keep them on a leash.
I read in a review of this park that a poor dog was attacked and killed a few months back from an unleashed dog. My dog was attacked by two unleashed dogs years back and the trauma is still present to this day. Be responsible people.
There were multiple swings we found that were fun to sway on and a cool rock shelter we stumbled upon even. See if you can find it!
