Make sure White Oak trail is open before you go.

This isn't the sort of road you'd take a vehicle on, nowadays - but it's great for nontechnical mountain biking, and this high point gives you nice views over the surrounding hills.

Miramar Beach offers a serene coastal escape with sandy shores and scenic vistas. Visitors can enjoy leisurely walks along the shoreline or explore the nearby California Coastal Trail, which provides stunning ocean views and connects to other local attractions.

Devils slide itself is nice and just to the south is the beautiful Gray Whales Cove beach. There is plenty of parking at both places. Two notes for cyclist: 1. cycling along Hwy 1, coming from Pacifica, requires climbing on a relatively narrow but highly frequented road. It is not a long climb until the turnoff to Devils slide, but it might be stressful for cyclists who are not used to riding in heavy traffic. Hwy 1 south of Devils slide has enough space for everyone. 2. If you cycle on Hwy1, then check the wind forecast beforehand. Dominant wind direction is NW, which means cycling southbound maximizes tailwind and minimizes breathing in all the air pollution from stinky cars.

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.

Black Mountain, situated on Monte Bello Ridge, is a popular destination for hikers and mountain bikers. With an elevation of 2,812 feet, it's easy to understand why. From the summit, the views of the Santa Cruz Mountains and Silicon Valley are breathtaking.
