17645 Hwy. 160, Rio Vista, CA 94571
Anglers targeting striped bass, sturgeon, or catfish will find the river access hard to beat, and the ten-lane boat ramp makes launches easy. Winter is the sweet spot: cooler temps, migratory waterfowl, and far fewer neighbors than peak season.
Shade-seekers and swimmers will be disappointed; most sites bake in the sun, the swim area at Seven Mile Slough is murky and awkward to reach, and algae bloom closures can cancel water plans entirely. Some reviewers also describe staff encounters that felt unwelcoming, so campers
Context for the broader area surrounding Cottonwood Campground, sourced from the federal Recreation.gov rec-area record.
This 42-mile stretch of two-lane blacktop is one of the last and best-preserved segments of the original Route 66, one of America's first transcontinental highways. This portion of the highway once included one of the most fearsome obstacles for "flatland" travelers in the 1930's: the hairpin curves and steep grades of Sitgreaves Pass, which characterize Old Route 66 as it makes its way over the Black Mountains of western Arizona.
The Historic Route 66 National Back Country Byway begins five miles south of Kingman at the McConnico exit off Interstate 40. To begin at the southern end, exit off Interstate 40 at the Topock/Golden Shores. Switchbacks access Oatman and the mining community of Goldroad.

Winter delivers the best camping conditions. Daytime highs reach the mid-50s with mornings in the mid-40s, creating comfortable weather for hiking and fishing without summer heat or crowds. Migratory waterfowl peak during these months, and boat traffic drops. Summer sees temperatures between 75-95°F, occasionally pushing past 100°F during heat waves. The Delta breeze provides evening relief during hot stretches. Strong winds can be an issue year-round. Reviewers recommend bringing extra guylines to secure tents.
Described as the best time: mild temps (45–55°F), quieter camping and good fishing.
