Acorn Campground is great for tent and RV camping. Warm weather so great for swimming. Good for fishing, boating (they have a launch), kayaking, paddle boarding and you can bring bikes and scooters for the kids.
Big Creek Lakes Campground, Colorado (close to Wyoming border): camping here is only open for 3 months out of the year: June, July & August. It's camping at over 9,000ft elevation and requires for you to be extra prepared for snow even in the summer months, bears, mountain lions, mosquitos, aggressive horse flies, leeches, strong winds, thunder storms and altitude sickness. They do provide water which tastes fresh like newly melted snow. You can boat, fish, even hunt at some spots with a permit, hike, and swim at your own risk (can be cold, leeches, snakes). It is truly beautiful up here and the drive up the Poudre river makes it worth it. You can also spend the day rafting down the river or fishing.
Bullfrog campground is located in Armstrong woods (Guerneville, CA). It's on top of a rugged drive up the woods and they are first come first serve basis. It's a close drive to the Russian river, but more tucked away from all the tourists. You can do some tough hill hikes through the Oaks or easier hikes through the Redwoods which remind me a lot of Muir Woods (but less crowded than that).
This place is north east of Sacramento. Coloma resort is what some friends call "Glamping", but it's so much more than that. You can tent camp (it's covered sites for camping too), rent a cabin or RV camp. Great sites along the river too. One negative, is you have to book way ahead of time, but it's well worth it. You can pan for gold, relax, or bike, hike along the river, and kids can play along several playgrounds for kids of different ages. A large grass area great for games, and if you are up for it, rafting, kayaking and fishing in the cold American river. You can also learn some history about the discovery of gold and check out Sutter Mill!
The 6 mile road to get into it is rough. With high rain season, you have to cross the creek and it may require a lifted type vehicle like a truck. There are some beautiful waterfall spots about 2 miles of hill climb from campground, well worth the hike. Water can be very cold though. Has bathrooms and is first come, first serve campground. Has a creek through the middle next to pretty much all sites. The stars at night are incredible. It’s about a 40 minute drive from Yosemite.
Must make early reservations. Campsites in beach are for tents only, they have a campsite across the road on the bay side for the trailers. Great for kids! You can walk along beach, fish, fly kites, beginner boogie boarding, kayak, paddle board and more!
This is the most picturesque campground! Short walk to a rocky beach across highway 1. Beach is not for swimming since the rip tides are dangerous. Abalone diving for experienced folks. You can find plenty of treasures on the beach including abalone shells (just make sure you leave the live abalone alone). During low tide you can find tons of crabs, sea stars, sea urchins and more! Walk through the redwoods by the creek for an incredible tour of the forest. A short trail to the old school house and you can also take the trail a short walk or drive up the highway for beautiful sunsets among the cliffs. Some spectacular views of the ocean. Kid friendly, family friendly, friends friendly!! One of my favorite campgrounds on highway 1! 10 mile drive to a winery, and fort Ross as well as Salt Point state park!
Del Valle is one of the most beautiful lakes in the east bay. The water is perfect temperature. Great hikes, paddle boarding, kayaking, swimming and beginner windsurfing. The only cons are that you have to drive to go swim and the campground isn’t really walking distance to swimming. It’s pretty hot in the summer and it has a rocky ground so it will be hard to get stakes on the ground. It’s trully beautiful and the wildlife views are incredible. The water is super clear and they have two beaches with a lifeguard which can get crowded. You can swim at your own risk past the marina though if you want to bike, hike or boat to those beautiful areas.
