About Mary Smith Campground
Overview
Mary Smith Campground is located off County Road 105, two miles north of the town of Lewiston, CA. This campground offers excellent fishing and tent camping.
This campground was picked as one of California's prettiest lake campgrounds in Sunset Magazine. Many of the sites have shore access to Lewiston Lake.
Recreation
The area offers excellent opportunities for fishing, kayaking, hiking and wildlife viewing. Pine Cove boat ramp is within four miles, and Fairview launching area on Trinity Lake is nine miles north. Motorized boats are limited to ten miles per hour.
Rainbow trout are abundant, and brown and brook trout are common. This is a good lake for a float tube and excellent fly fishing. The area offers wonderful wildlife viewing opportunities.
Facilities
There are six Glamping unit sites all with on-site fire pits and picnic tables. The sites offer fair to outstanding privacy. There are both flush and vault toilets, and drinking water is provided.
With the exception of the large cluster of sites at the campground entrance (Glamping camping site #'s 2, 3, 4, 5a, 5b, and 9 ADA compliant), the remaining sites are arranged in small groups. No trailers are allowed and there are no parking spurs.

FAQ
How do I get a reservation at Mary Smith Campground?
Campsite Sniper's current snapshot shows none of the 594 tracked site-nights open for online reservation at Mary Smith Campground. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. 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 Nov 2, 2026 18:20 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.
When is the next open date at Mary Smith Campground?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Mary Smith Campground begins Apr 1, 2027 — about 150 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before Apr 1, 2027.
