• Modini Mayacamas Preserves

This session will introduce you to the preserve and our rules and will qualify you to hike independently on the Sanctuary. The orientation session is outdoors. Bring a chair or cushion to sit on, if you like. You are welcome to stay afterwards to hike independently or join an optional guided hike until 4pm to explore some nearby areas. If you’re staying to hike, bring a snack and water.

Rob Roy Flat, the big pull-out about 25 minutes up Pine Flat Road, just before you cross under the big power lines. Pine Flat Road starts just east of the Jimtown Store, which is northeast of Healdsburg. 

Steep, Wild Country, No Facilities, No Pets
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.
