June 23, 2025, View of the Pacific Ocean from Russian Ridge Open Space Preserve

From up here on the ridge you get great sweeping views across the foothills. On a clear day you can see out west to the Pacific Ocean.

Borel Hill is my favorite place to watch spring flowers. The western slope near ancient oaks (5-10min west of Borel Hill) are covered with orange California Poppies and purple flowers starting in April. Borel Hill itself peaks around mid May and has a wide variety of flowers. The show lasts only a few weeks until end of May. The peak time and flower intensity varies from year to year, so come several times between April and May. There is small summit NW of Borel Hill and a narrow dirt trail leads you to a rock within 2 min. The rock is big enough for 2-3 to sit on. On a sunny day, the rock is nice warm even if the air is cold. Good views on the ocean and the Bay.

Here, the Steve's Creek Nature Trail and the Canyon Trail intersect. A lovely patch of grass surrounds the junction, making it an ideal spot for a break.

This fantastic tavern, founded in 1852, is the second oldest in the state. It features a large, beer garden-style outdoor area with plenty of shade. An extensive beer and food menu makes it a perfect stop to enjoy a brew and some great food after a ride.

Russian Ridge is an incredible 3,137-acre preserve that boasts a rich diversity of plants and wildlife, steep forested canyons, and grasslands, with abundant wildflowers in the spring. The open ridge tops provide breathtaking panoramic views of the Santa Cruz Mountains, the Bay Area, and the Pacific Ocean, making it one of the most scenic preserves in the area to enjoy a picturesque ride.

Long Ridge Open Space Preserve is a 2,035-acre preserve that follows Long Ridge in the Santa Cruz Mountains. There are a variety of trails that can be used for hiking, biking, or horse riding. This is a dirt trail area, so it is more suited for gravel bikes or a stout touring bike; a hardtail would be ideal. In addition, this is a preserve and not a park, so there are no facilities that you would normally expect in a park, such as bathrooms, drinking water fountains, picnic tables, snack bars, or stores.

At the convergence of the Long Ridge Trail and Long Ridge Road, you will find the Wallace Stegner Bench. This overlook was one of the favorite places of author and conservationist Wallace Stegner. There are panoramic views of the Santa Cruz Mountains and the Pacific Ocean to be had from here. However, if you come up by bike, the dirt trail is best suited for a touring bike with decent tires or a gravel bike.
