Sycamore Ranch is Yuba County's reservable river campground
Sycamore Ranch has 56 reservable campsites and two day-use pavilions near the Yuba River; nearby Hammon Grove is a separate county park.
For overnight camping, choose Sycamore Ranch. The current reservation system has 56 individual campsites, and some can be combined for group camping. Reserve online or call 530-749-5430. The on-site caretaker cannot make or cancel a reservation.
Day use is a separate choice. Sycamore Ranch sits where Dry Creek meets the Yuba River and has two reservable picnic pavilions. Electrical service is limited. Call 530-749-5641 before counting on power or a pavilion. A campsite does not reserve a day-use shelter.
Hammon Grove is the nearby county-park name that is easy to mix up with Sycamore Ranch. Treat the two as separate parks. Use the Sycamore reservation listing for camping and the county parks page for current Hammon Grove notices instead of assuming the facilities or reservations carry over.
The river is its own decision. Yuba River releases and flows can change quickly, and the water can stay very cold even on a hot day. Check the Yuba Water Agency’s current river conditions before entering. A campsite or pavilion reservation does not mean the water is calm or safe.
Where to see it
Book a Sycamore Ranch campsite through Yuba County's reservation system. Check the day-use listing and river conditions separately before choosing picnic or water access.
