Escape the city and become a steward of the breathtaking land at Lillian Hill Preserve! Join us for a unique opportunity to explore this stunning open space preserve located in the headwaters of the San Diego River. As a volunteer, you’ll connect with fellow nature lovers, soak in the beauty of the landscape, and maybe even spot wildlife like deer or snake! Together, we’ll help care for this conserved land by repairing recreational trails - vital work that keeps the preserve healthy and accessible for all to enjoy. This month we will focus on trimming the trail with hedgers, weed whackers, loppers and hand pruners to prepare for our upcoming Sunset Hike. All tools will be provided.
This Preserve Stewards event takes place from 8:00 am to 12:00 pm on San Diego River Park Foundation preserves near Julian or Descanso, approximately a 1.5-hour drive from downtown San Diego.
Get outside, give back, and experience the joy of spending time in the wild beauty of San Diego!
What is Lillian Hill?
An expansive 80-acre property at Lillian Hill was placed on the market for potentially five building sites. Surrounded by National Forest, its development would have had a significant impact. We set out to buy this land to conserve it forever for the badgers, cougars, eagles, falcons, majestic oaks, and more. Now that it has been purchased, we can begin removing the scars of decades of land use and start the healing process.
