Pitch In For PQ!

We know you love it! PQ needs your help! 


We are turning once again to YOU, our generous trails community, seeking your support to raise funds for additional enhancements and projects scheduled for late 2023/early 2024.

**Thanks to an anonymous trail lover, the first $5000 in donations has been matched for double the impact!  

Funds raised during the PITCH IN FOR PQ campaign will support repair and improvements at: 

  • Sycamore Crossing
  • Switchback Trail
  • Upper Cobbles
  • Little Waimea
  • Lopez Canyon

Los Penasquitos Canyon Preserve, fondly referred to as PQ, a beloved trail haven drawing hundreds of outdoor enthusiasts every week. Encompassing over 4,000 acres, this expansive area features a network of trails, including historic ranch roads and scenic creek crossings, catering to mountain bikers, hikers, equestrians, trail runners, and more!

For decades, SDMBA (San Diego Mountain Biking Association) has partnered with City and County staff to improve the trails in the canyon. Trail improvement projects at Duck Pond, Side Hill, Cobbles, and Switchbacks, have received valuable support from SDMBA. In 2016, SDMBA hand-built the Appendix Trail, while more recently completing the vital connectors Deer Creek and Barrel Roll.

Read more about SDMBA's work and advocacy efforts in the area HERE.

The creek crossings within the canyon are particularly vulnerable to seasonal damage, requiring ongoing improvements. Thanks to the generous contributions of individuals and corporate sponsors, SDMBA successfully restored the Wagon Wheel Crossing in late 2022. 

Your generous donations will play a crucial role in making Los Penasquitos Canyon Preserve even better!

PQ Needs You!  Thank you for your generous support so PITCH IN FOR PQ!

Help us reach our goal of $25,000!

Our work is supported by generous donors like YOU!

We are gearing up for a very busy 2023-24 Trail Work season on projects throughout the county from Mount Laguna to Daley Ranch to Chula Vista, Tri-Canyons, Otay Valley Regional Park, Elfin Forest, Penasquitos, Black Mountain and more!  When you donate to this general fund, we promise to use your gift where it's needed most.  Whether that's covering operating costs, clearing a fallen tree,  or buying lumber for a new bridge or a shovel for a volunteer to use, we'll make sure your money has the most impact on our trails and our community.

Past contributions and grants have allowed us to purchase and maintain a mini-excavator, a motorized wheelbarrow, a plate compactor, a water buffalo and water distribution equipment,  and loads of hand tools and materials to help us maintain and build trails.  In addition, your support provides resources for our staff and our volunteer trail experts to partner with user groups, land managers, and policymakers to improve access and your trail experience.  Learn more about the impact of our work HERE.
