About Boat-in Sites (lake Sonoma)
Overview
Lake Sonoma's Boat-In Sites are scattered around beautiful Lake Sonoma, only a 45-minute drive north of Santa Rosa and a two-hour drive from San Francisco.
BOAT-IN CAMPGROUNDS ARE ACCESSIBLE BY WATER OR HIKING ONLY, THERE IS NO VEHICLE ACCESS TO ANY BOAT-IN CAMPGROUND
World famous vineyards and a land rich in history surround the lake, where visitors enjoy boating, fishing and exploring the area's extensive trail network.
Recreation
The lake provides great boating and swimming opportunities. Anglers fish for large and smallmouth bass, catfish and sunfish. A small native population of rainbow trout exists in the waters as well.
Hikers, mountain bikers and horseback riders enjoy exploring several miles of trails that meander along the shoreline.
Facilities
The lake hosts 108 boat-in campsites. Some sites lie close to the lake's ski zones while others are in more secluded regions perfect for fishing or swimming. Boaters who wish to camp/sleep on their boats may anchor anywhere within the park, but boats must be equipped with anchor lights. If boaters wish to tie up to the shore, they must be at one of the designated campgrounds.
Natural Features
Lake Sonoma is nestled in the beautiful coastal foothills of Sonoma County, California. The area typically has cool, foggy, wet winters and hot, dry summers. Temperatures average in the upper 90s during the summer with short periods of higher heat.

FAQ
How do I get a reservation at Boat-in Sites (lake Sonoma)?
Reservations for Boat-in Sites (lake Sonoma) are made through Recreation.gov. The current snapshot shows substantial availability: 18,943 of 19,764 tracked site-nights are open (95.8%), though availability can change. Campsite Sniper has also detected 54 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Sep 18, 2026 16:19 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.

Campsite Sniper detected 14 site-date openings at Boat-in Sites (lake Sonoma) in the last 7 days, 54 over 30 days and 54 over the last 90.
Which day of the week had the most detected openings at Boat-in Sites (lake Sonoma)?
Wednesday accounted for the largest share of the openings Campsite Sniper detected in the last 90 days: 27 of 54 (50%). Days reflect when Campsite Sniper first detected each opening, not when the change occurred upstream.
Can I get a multi-night stay at Boat-in Sites (lake Sonoma)?
144 three-night openings are showing, counting only runs where the SAME site is free for all three nights. The soonest starts Sep 18 at site BM02. Confirm and book on Recreation.gov.
Which month has the most availability at Boat-in Sites (lake Sonoma)?
January 2027, with 3,348 open site-nights in the current snapshot of 3,348.
How far ahead of a stay do openings appear at Boat-in Sites (lake Sonoma)?

As of the Sep 18, 2026 snapshot: the next open date is Fri, Sep 18 and the next open weekend starts Fri, Sep 18. Detected openings can add earlier dates at any time; a free Campsite Sniper alert catches those the moment they appear.
