I'm not big on camping in populated areas. I enjoy going up to Plumas County. There are so many great places hidden up there. You can also find several camp grounds in the area. The 4 wheeling up there is wonderful.
I also camped at Pismo Beach for the first time last spring. If you don't mind hanging out with fellow campers, it is a blast! Great dunes out there. But the sand can be pretty killer!
Just spent a few nights up at the McCloud river, around the Mt Shasta area. Awesome. Lots of trout. I just moved to this area (santa cruz) a couple months ago, so the only other place I've camped was up the Plaskett Ridge road, just off the 1 in the Big Sur area. Killer views of the ocean and cliffs from about 2500 ft up on the ridge.
Since it's local for me... just about anywhere in the Sierra national forest. Hundreds of places to camp. All within a couple hrs. drive for me. I prefer anywhere primitive near a stream or lake, but sometimes a developed site works, too. Mono Hot springs is one of my favs if it's not too crowded. Spent lots of time there as a kid. Huntington lake has lots of sites. Courtright lake @ the S.E. side of the Dusy/Ershim trail has some cool primitive lake side spots. (if you have a 4x4) Typically, I prefer the higher elevations.
Thanks for the recommendations guys! I have been looking for a few good camping spots and cant wait to try some of these out! Anybody have any good places to stay in a cabin, my wife hates camping so its hard to get her to go for more than 1 night unless there is a cabin! Thanks!
