Mountains Restoration Trust

Come Meet Us at the Top of the World


Cold Creek Preserve is growing! Through the recent purchase of two new properties, we are increasing the preserve size by 85 acres. To celebrate this great news, MRT is hosting an Open House - or rather an Open Preserve - on November 8th from 9 a.m. to 1 p.m. at the Top of the World (otherwise known as the Lois Ewen Overlook and Topanga Lookout Trailhead).


We will have a welcome tent at the Top of the World on Stunt Road filled with information (including new trail maps) and refreshments. MRT staff will be on hand to answer questions about the Preserve and the Santa Monica Mountains.


Take a guided tour along the pristine Canyon Preserve Trail, which will include talks by experts in conservation biology, wildlife and native plants. This is a rare opportunity as the trail is normally closed due to the threat of New Zealand Mudsnail contamination in the creek. A boot cleaning station will be set up for the tour. Reserve your spot by clicking HERE. A fee is required that will go towards further restoring and protecting the preserve, and space is limited in order for donors to enjoy an intimate hike. The hike starts at the upper trailhead with an optional shuttle ride at the end, back to the top.


Enjoy an unguided, mile-long hike on the ridge-top trail to the lookout, where the views are spectacular. See not only sweeping island and city vistas, but capture a bird`s eye view of the Preserve and its recent acquisitions. Come see for yourselves what we are celebrating.


The larger of the two new properties, affectionately referred to as the Topanga Connection, is 80 acres on the east side of the Cold Creek Canyon Preserve. It contains habitat ranging from dense chaparral to wetlands, and two year round streams. This key parcel continues the effort to link the Cold Creek Preserve to the Topanga State Park, providing a critical habitat connectivity for wildlife movement, as well as two other protected conservation parcels to the east. Connecting these properties not only increases the size of the preserve; it also helps to maintain the purity of the wetland areas in and around Old Topanga Creek, which flows into Topanga Creek that provides habitat to the endangered southern steelhead trout.


The second property is five acres located in the Cold Creek West Preserve. Cold Creek meanders through half of the property, making it rich in riparian habitat.


If you would like to take a more active role in the day`s festivities, come ready to work. Our team of AmeriCorps volunteers will be removing invasive purple fountain grass from along Stunt Road and a group of UCLA volunteers will be doing trash clean-up and graffiti removal from the Topanga Lookout.



The Santa Monica Mountains, a unique transverse range, running along the western edge of Los Angeles County`s LA Basin and the San Fernando Valley and ending in Ventura County, represents the collision of urban sprawl and the wild, producing enclaves that neither belong entirely to the city nor to the mountains.

For more than 30 years Mountains Restoration Trust (MRT) has worked to preserve, protect and restore this fragile ecosystem by offering responsible preservation and restoration programs, acquiring resource-rich land, and offering educational and recreational activities to the public.
