If the first place you think of when you hear “the Sierra Nevada mountains” is Tahoe or Yosemite, I would strongly encourage you to explore points north of Truckee/Tahoe in the Plumas National Forest. And, a great place to stay while exploring the area is Little Bear RV park. This clean, quiet, and very family friendly campground offers a mixture of full and partial hookup sites, plus cabins. It’s right on the Feather river, with a refreshing swimming hole walking distance from the campground. Plumas Eureka state park offers a number of hikes that even little ones can manage. It also has great picnic areas on the creeks that run through the park. Within a 30 minute drive are a number of gorgeous alpine lakes. Gold Lake is especially beautiful and peaceful. I spent 5 nights here and while I love the more “famous” Sierra attractions, I have to say: I didn’t miss the crowds. Plumas is what Tahoe was like in the 1950’s. Highly recommended.
