Waterfall Loop Nature Trail
The Waterfall Loop Nature Trail
On the Waterfall Loop, you’ll hike through dense woods of deciduous and evergreen trees while listening to running water and cascading falls. Swanson Creek and the waterfalls in the park are filled with water from rainfall and the natural springs in Uvas Canyon. The creek and multiple waterfalls are what make this park and this trail memorable. Late winter and early spring are the optimal times to enjoy the waterfalls and Swanson Creek at their fullest. Although the creek usually has water year-round, it’s typically less full by summer and fall, and some of the waterfalls can dry up or slow significantly. Upper Falls, at the halfway point of the Waterfall Loop, typically runs most of the year, with less flow in the warmer, drier months.
Swanson Creek
The Waterfall Loop is a one-mile loop that is a beginner-moderate level hike, with its highest elevation at 500 feet. It’s a popular choice for families and those with dogs. It can easily be completed in an hour. But expect to spend more time if you want to take a slower approach, stopping for photos, breaks, and enjoying the scenery along the way—which we highly recommend!
Hitting the Trail
From the day use parking lot, you must walk a short distance to reach the start of the Waterfall Loop Trail. Pick up a map here before you begin.




The Waterfall Loop Nature Trail trailhead
You’re ready to hike! The Waterfall Loop has markers to help guide you, along with your map. As you walk through the woods surrounded by nature, you’ll have great views and photo opportunities as most of the trail travels along Swanson Creek.
Granuja Falls
As you proceed along the trail, you’ll climb some stone steps and cross a bridge overlooking Swanson Creek and Granuja Falls. Here you can take some great photos and view the blue-green waters of Granuja Falls, which has short cascading falls.

As you continue the Waterfall Loop, take a moment to spot the numbered plants and trees along the way and find the corresponding descriptions on the Trail Guide to learn more about them. There are several smaller, unnamed falls along Swanson Creek during the wetter months. You’ll also cross several bridges over Swanson Creek along the path.

Take a break on the way to Black Rock Falls
Before you reach the halfway point of Waterfall Loop, you’ll reach Black Rock Falls on the right side of the trail.
Black Rock Falls
You can climb a narrow space along the left side to get a closer view—just be careful, as it can be wet, muddy, and slippery. This waterfall has a decent flow after rainy weather.
Black Rock Falls
In the winter, you might see ladybug clusters on the bridge by Black Rock Falls and on plants along the trail.


Myrtle Flats
You'll arrive soon at Myrtle Flats, which is about halfway around the Waterfall Loop path. This is a good place to enjoy a break, some water, and a snack if you need it, and there is even a picnic table here.
Myrtle Flats

Path from Myrtle Flats towards Upper Falls & Basin Falls
From Myrtle Flats, you'll take a short path that proceeds over a bridge and past the creek.

Basin Falls
Next, you'll reach a fork in the path. Head up to the middle path to view Basin Falls, a pretty fall with two larger cascades and a little pool between the first and second drop. (The path to the far right is Knobcone Trail and is not part of the Waterfall Loop.)

Basin Falls
The walk along the path to Basin Falls is very scenic, as the stream from the falls flows along the trail and through the trees.

Upper Falls
The left path up from Myrtle Flats leads to Upper Falls, usually the largest waterfall.

The short path to Upper Falls

Upper Falls
This fall usually flows in the summer and fall, too, but with a much slower flow. From Upper Falls, you can also access the Contour Trail, a much longer loop that will take you back to the main entrance. (This trail can be closed in wetter seasons due to flooding.)
Upper Falls
Once you've taken in the beautiful Upper Falls and the creek below it, head back down to the trail and back across the bridge to Myrtle Flats. From just below Myrtle Flats, you can cross Swanson Creek on another bridge to continue on the Waterfall Loop as it heads back down towards the start of the trail. (Note that after heavy rainfall, the bridge to the other side of the Waterfall Loop Nature Trail can be closed; if that's the case, you can simply walk back from Myrtle Flats on the trail you came in on. Both halves of the loop follow the Swanson Creek.)Other Falls
There are two other waterfalls that you can view that are not located on the Waterfall Loop Nature Trail:- Lower Falls: The trail to this waterfall is accessed just before you reach the Waterfall Loop Nature Trail. It's just up the road from the day-use parking area and to the right just before the road crosses over Swanson Creek. Look for the sign for Lower Falls and head down some stairs and along the Swanson Creek Trail, connecting to the Uvas Creek Trail. (The Uvas Creek Trail can be closed during winter due to Uvas Creek water levels being too high.)

Downstream from Lower Falls
- Triple Falls: Accessible from the Alec Canyon Trail connecting to Triple Falls Trail. This path leads a different direction than the other trails and is about a 2.5-mile trail roundtrip, taking about an hour and half to complete. It's a more intensive hike, with more inclines and switchbacks. Triple Falls tends to dry up in the warmer months.
Getting There
Uvas Canyon County Park is open daily, from 8 am until sunset. Because of the limited parking and space, they do require reservations for day use, so book your arrival time slot ahead of time. Please visit gooutsideandplay.org to make your reservation. Allow about 35-40 minutes to drive to the park from Gilroy, particularly as the road grows curvy and you’ll need to drive slowly. From Gilroy, you’ll take Highway 152 W (Hecker Pass Highway), turn right on Watsonville Road, left onto Uvas Road, and then left on Croy Road. You’ll follow Croy Road all the way into the park, parking in the day-use parking area. (Don’t continue up the road—there’s no day-use parking allowed in the campground area.) Be sure to place your printed copy of your reservation in a visible spot on your dashboard; the rangers do come around to check.Camping
