This mellow hike on the Los Penasquitos Canyon Trail takes you to the highlight of the park, a waterfall plunging through volcanic rock. Along the way you'll encounter a forest of giant California live oaks and sycamores, the grave of European royalty, and a year-round stream that many endangered species call home. Nestled in a valley insulated from surrounding development, Los Peñasquitos Canyon Preserve is not only one of the most bio-diverse areas in SoCal, but it's also one of the largest urban parks in the USA.

Gear For the Hike
- This is a straightforward hike that most folks do in fitness or casual clothes.
- Bring at least 1L of water.
- If it's been raining, there can be some big puddles and small stream crossings. I use trail runners and they work great.
- There can be ticks and bugs in the lush growth around the creek. I use insect repellant here.

Los Penasquitos Canyon Trail Maps
There are over 12 miles of trails at Los Peñasquitos Canyon Preserve, and this hike guide will take you down the main South Side Trail to the waterfall. A few notes on the trails here:
- Overall the trail is flat with a few small bumps.
- If the falls are too far, you can cut it short by taking on of the crossings before that and hiking back on the other side.
- Here's an official trail map for the park.
- We are going to take small parallel side trails between Peñasquitos Creek and the larger South Side Trail. These trails are small, generally shaded, and less busy than the bigger South Side Trail, which is a dirt road.
This route takes you on the small trail between the creek and dirt road. Most people just take the dirt road. As long as you stay between the creek and road, you're going in the right direction. - If there's been a lot of rain, the small side trail can be flooded. If this is the case, just head over to the South Side Trail and continue there.
When the trail is covered in water, you can get your feet wet or just head over to the main South Side Trail. - This is an out-and-back hike. When you get to the waterfall, just turn around and come back the way you came. If you just want to return quickly, you can take the main dirt South Side Trail back. You can also cross over and take the North Side Trail, crossing back to the south side of the creek wherever you'd like.
When you get to the waterfall, you'll see the North Side Trail heading back on the other side of the creek. You can take that back as well. It's wide and exposed, similar to the main South Side Trail.

- Los Penasquitos was the site first Mexican land grant in California, which happened in 1815. The Mexican government gave out land parcels like this to retired soldiers.

Los Penasquitos Canyon Trail Hike Directions
If you want to do a small side trip, go straight at that last junction to visit the Carson's Crossing boardwalk over Peñasquitos Creek.
From here just go back the way you came, or take the South Side Trail the whole way, or cross over and take the North Side Trail back.
