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!

While you’re in the area, make sure to visit the Egyptian Building nearby!

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 and leash up your dogs. 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!


The hike starts you up at the top of the hill with beautiful views.  You will then be hiking down into the canyon:

Almost the entirety of the hike is shaded.  My type of trip!

You will have to cross multiple creeks.  Right after a rain may prove to be extremely challenging:

She is only let off leash to cross creeks at her own pace so she doesn’t get choked:

We came across a couple swings:
