In the shadow of Mount Saint Helena lies thousands of acres of protected lands. The gateway to this natural landscape is Audubon Canyon Ranch’s Modini Preserve. The preserve totals 3,000 acres and sit on the slopes of the Mayacamas Mountains above Highway 128 in the Alexander Valley.
A favorite spot for birding, the Modini Preserve is traversed by Pine Flat Road, a public county road that meanders through the Preserve allowing visitors to enjoy the views and birdwatch from roadside pullouts anytime without appointment. Please drive very cautiously, this is a one-lane winding road with very limited sight lines.
Steep, Wild Country, No Facilities, No Pets
When visiting the Modini Preserve, please dress for the weather and bring at least one quart of drinking water. You may also wish to bring a hat, an extra layer, and a snack. There are no toilets, no water fountains, no restaurants, no trash collection...this is a primitive and wild place! Please wear appropriate clothing and footwear for the outing. For hikes you will want shoes that protect your toes and give you good traction on uneven ground, such as sneakers or hiking boots. Please leave your pets at home.
3/4/19: Pine Flat Road is affected by a FULL CLOSURE At 5500 block due to slide. Staff-led hikes are on hold until further notice.
The Preserve hosts public hikes guided by knowledgable ACR staff and local experts.
All hikes are offered by fee or suggested donation of $20 per person ($15 per ACR member/student, under age 18 free). Register online at Eventbrite. Contributions support the preservation, education and conservation science programs of Audubon Canyon Ranch. All donations are greatly appreciated!
Unless otherwise noted, outings meet at the listed start time at the intersection of Pine Flat Road and Red Winery Road, about 7 miles northeast of Healdsburg. From there we carpool into the Preserve. Please see the Directions page.
In order to hike independently on the Modini Preserve, ACR asks that you attend an Access Orientation session, which will qualify you for future hiking adventures. The orientation takes place outdoors, so bring a chair or cushion to sit on if you like. There is no hiking during the orientation, but you are welcome to stay afterwards to hike independently. See the online calendar for Access Orientations.
