Top Bay Area Hikes: St. Hilary Church

St. Hilary Header

Try the St. Hilary Church hike at the Old Saint Hilary’s Open Space Preserve in Tiburon.

Old St. Hilary’s Open Space Preserve is a 122 acre Marin County Park that overlooks the Bay with spectacular panoramic views of all three bridges – The Golden Gate Bridge, the Richmond Bridge, and the Bay Bridge.

It’s just over one mile, and easy enough for the whole family to walk, which makes it a top Bay Area hike.

The nature preserve is not only known for the perfect panoramic views of the entire Bay, but also for its rare wildflowers, the most famous being the Tiburon Jewelflower. This endangered flower blooms May through June. 

Church History

The Miwok tribes transferred the land to a Mexican land grant, which was then purchased by an immigrant from Ireland, who later married the daughter of the Mexican commander of the Presidio.

Then they had a daughter who married a Canadian.  That couple allowed the archdiocese of San Francisco to build a church on their property. And all this happened before 1888!

Later, in the 1960’s the people of Belvedere and Tiburon formed a trust to protect the church and its surroundings. Because of them, it’s now a well taken care of spot for everyone to enjoy. 

Marin Bonus

We always add a little bonus to this hike by stopping at our favorite juicer, Sun Life Organics in the Larkspur Landing, Marin Country, shopping area. If you’ve never had a Sun Life Mint Chocolate Chip smoothie, can you even say you have lived?
