Confirmed from Castle Rock State Park's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
Park offering 34 miles of hiking & horseback riding trails among redwoods & other regional trees.
What runners say about Castle Rock State Park
“The park’s facilities are well-maintained, with clean restrooms and convenient parking.”
“Two visits to Castle Rock State Park, one in February when it was very cold, windy, foggy and beautiful and the second in March on a warm day.”
“Bring lots of water; some sections of trails are totally exposed to the sun with no shade at all.”
“The trail was well-marked, and the terrain was varied, with rocky outcroppings and wildflowers adding to the scenery.”
“its a solid spot if you want actual quiet and tall trees, definitely better than some of the overcrowded parks nearby.”
I’ve lived in the South Bay for 15 years, and this is the first time I’ve visited this place. Castle Rock State Park is an amazing place for outdoor activities! The scenery is absolutely stunning, with numerous beautiful trails suitable for hikers of all levels.
A few weeks ago I hiked the Castle Rock Loop Trail and Saratoga Gap, which were amazing and relatively easy to hike. Parking was easy to find, with many trail maps and guides available. Castle Rock was a pretty amazing sight, interestingly shaped and great for photos.
Super duper beautiful park with some incredible hikes and views! There are quite a few rock formations to climb on, which provide even more great lookout points. I went on a Saturday, arriving at about 11, and parking was a bit hard to find unfortunately. Next time I hike here i’ll try to arrive a bit earlier.
## Ridge Trail Review I recently hiked a moderate to strenuous ridge trail that offered breathtaking panoramic views. The trail was challenging, with steep inclines and uneven terrain, but the scenery made it well worth the effort.

“Paid parking lot at trailhead, but there is also free parking on the sides of the street outside if you can beat the rush (ideally before 8:30am).”
“Be careful on some of the trails, you have to climb over large boulders and sometimes use steel cables to hold onto with narrow trail parts and steep drop offs.”
“its a solid spot if you want actual quiet and tall trees, definitely better than some of the overcrowded parks nearby.”
