Purisima Creek to Grabtown Gulch to Borden Hatch Mill Loop

Recently I went down to Half Moon Bay and decided to hike the Purisima Creek to Grabtown Gulch to Borden Hatch Mill Loop. I’ve been to the Purisima Creek Redwoods Open Space before when we were out for vacation. I enjoyed it last time, so I thought it would be fun to come back.

  • Ranges of elevation from 400 feet to 2100.

  • Purisima Creek to Grabtown Gulch to Borden Hatch Mill Loop
  • Whittemore Gulch Trail, North Ridge Trail

One thing to note is parking can be a nightmare. I arrived on a weekday and snagged the last spot, so I can only Purisima Creek Redwoods Open Space Preserve is packed on weekends.

Hiking the Purisima Creek to Grabtown Gulch to Borden Hatch Mill Loop:

The trail is rated as a moderate trail due to the elevation changes. You do climb about 1400 feet. There are plenty of ways to make the trail easier included out and back. Taking it the way descrived removed steep downhill which makes it a little easier.

As mentioned, I arrived on a weekday. I snagged the last parking space. After getting ready to go, I discovered there is a restroom at the trailhead. What great luck.

The first 1 mile is a flat, wide trail. Once you reach the trail junction at about 1 mile, you continue straight on Purisima Creek Trail.  It’s a relatively flat grade.  I nearly stepped on a few slugs, which I remember from last time being “a thing.”

Around 1.2 miles, you reach the junction for Grabtown Gultch Trail; you’ll want to continue straight. This is where grade increases, but it’s still a relatively easy climb.  You go across a couple of bridges.  Around 2.4 miles, the Purisima Creek Trail bends left, and you’ll keep going uphill. This is where the climb gets more challenging but not unmanageable.

Next atvPurisima Creek to Grabtown Gulch to Borden Hatch Mill Loop, you’ll turn left onto the Craig Britton Trail (which is a hiking-only trail).

Just under 5 miles, you’ll reach the Harkin Ridge Trail, which climbs back to the Purisima Creek Preserve Trailhead. If you’re feeling inclined, you can add a couple more miles by turning left onto North Ridge Trail and then heading back on Whittemore Gulch Trail.

The rest of the way back on the is fairly low key. The wider trailhead and easy to move trail makes it enjoyable.  I love looking at the large pictures of Redwood Trees.
