Sims Flat Campground

4 ReviewsAdd Review

The sound of the Sacramento River flowing nearby sets the tone at this Forest Service campground, where 17 sites spread across open terrain with varying shade options. Campers can choose between full sun exposure or ample shade depending on their preference, with sites like #4 and #17 offering particularly good tree cover during hot weather.

Most sites accommodate RVs up to 24 feet without requiring leveling, though the access road can present challenges. Train traffic on the opposite side of the river creates regular noise throughout the night, including whistles and wheel sounds that carry across the water. "Sound of the water was nice to sleep to," notes hannah, though the railroad activity provides a contrasting soundtrack.

A paved interpretive trail loops through the campground with historical markers about the former conservation corps camp that once occupied this site. The path leads to river access points, though getting into the water requires some effort due to the bank conditions. Small gnats can be persistent around the eyes, prompting the campground host to wear protective netting. Clean restrooms with working lights and toilet paper serve the sites, with a newer facility at the far end of the campground.

The location works well as an overnight stop for travelers, staying typically uncrowded while providing easy access to I-5. For additional options in the region, campers can explore camping spots near Shasta National Forest.

Many campers appreciated the well-spaced sites with good shade options and clean facilities along the Sacramento River. Train noise from across the river frequently disrupts sleep, though the campground itself remains quiet and uncrowded.

Great Overnight Stop

This is a nice little campground along the Sacramento River. The sites are well spaced and, depending on your preferences, plenty of options in terms of full sun or shade. The campground was empty when we pulled in mid afternoon on a Thursday. In the morning there were two other sites that were occupied by tent campers.

Most sites would easily fit our 24’ RV. We chose site #4 as it offered ample shade in these over 100° temps. No leveling was required. Site # 17 was also nicely shaded and offered even more privacy.

There are several bathrooms, but cant attest to their condition. The one at the far end of the campsite looks relatively new.

There is a nice little paved walk around the campground with signs giving the history of the conservation core camp that was located here at one time. The path takes you along the river, but access is a little challenging if you want to get in to cool off. There is also a several mile out and back ‘hike’ along a forest road that begins near the entrance of the campground

The only cons for this campground would be the trains that pass by on the opposite site of the river. There were several during the night with whistles, rumbles, and screeching wheels. There is also some road noise. Other con would be the little gnat-like bugs that are determined to embed themselves in your tear ducts. The campground host sports mosquito net head wear so be warned!

Overall, a great little one or two night enroute stay campground.

Next to the river

Nice campsite just off of I-5 and on the south side of the Upper Sacramento river. The train will wake you up at least one time in the night however. Beautiful view of Mt. Shasta and a popular raft put in (experienced only- whitewater).
