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.

Great place to get a view of the historical rolling foothills of Byrne Preserve, which will change in color throughout the year, from bright green in the spring to a toasty yellow once the summer hits.
