Trail Descriptions and Etiquette

Who We Are

Irish Hills Natural Reserve is a geographicallydiscrete 720 acre riding area, yet it contains over 8
miles of trails. Many loops are possible on mostly
singletrack trails. The rocky, serpentine landscapecontains chaparral, oak, grasslands, and riparian habitats. The area’s wandering distribution of
doubletrack attests to its mining history and also
serves as a link between the singletrack sections.

Since 1987, CCCMB has been working to keep local
trails open for trail users. CCCMB members haveinvested thousands of hours of volunteer effort in
the repair of trail erosion, as well as in constructing
new trails. Additionally, CCCMB actively represents
mountain bikers and other trail users in the political arena. Responsible trail use and observation oftrail etiquette are of fundamental importance. This
helps to ensure continued trail access for all, prevent erosion and reduce user conflict. As always,
all who enjoy this land — hikers, runners, equestrians, and cyclists — are invited to join in andhelp ensure continued access to our public trails.

When riding these trails, please be mindful ofthe etiquette recommended by the International
Mountain Bicycling Association (IMBA) and CCCMB:
1. Only ride on open trails.
2. Leave no trace.
3. Ride in control of your bicycle.
4. Always yield trail to others.
5. Never scare animals or people.
6. Plan ahead.
