Enid Pearson-Arastradero Preserve offers rolling grasslands mixed with oak and evergreen trees. The trail system starts on pavement and transitions to packed dirt and gravel—great for bikes with wider tires or a solid gravel setup. Keep an eye out for deer, coyotes, and even bobcats, and take a moment to pause at one of the benches or by Arastradero Lake to enjoy the open views.

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.

This winding side road is very lightly trafficked and carries you between Stanford and the Palo Alto hills with partial shade the entire way. On the east side of the road you will find Frenchman's Tower, and old brick landmark.

Stanford's historic cacti garden boasts a wondrous variety of succulents with well-maintained packed walking paths that guide you through its grounds. You'll have to dismount the bike but the cacti are well worth a stop!

The San Francisco Bay Trail is a flat, paved trail that runs along the border of the bay. It is a great place for a run because it is traffic free and has great views.
