I know each park is different and unique in their own way. But wanted to ask your opinion. What has been a couple of your favorites? My son is getting old enough that I will be taking him to a few and I am just planning ahead to see where I want to go.
I am a fan of all the national parks and forests, but my top picks for camping are:
Inyo National Forest a lot. If you go in (from West to East) off of the 395 toward Glacier Lodge...great hiking, camping, amazing glacial lakes, lowest glacier in the 50 states. You can easily day trip or camp for days. There are a few big "hill climbs"...depending on your son's age it could be tough.
Sequoia national park and Kings Canyon...I haven't actually been there, but some of my closest friends rave about it....literally rave about it. There are some easy trails for kids.
Big Cypress National Forrest (if you like swamps and marsh lands). Flat trails, but you do have to deal with mud, mosquitos, snakes and alligators...these last two aren't a problems unless you decide to poke them.
Death Vally is amazing. There is so much to do there. If you go up by Wild Rose Peak to look down on the entire area. Or stay down in the valley and go out on day drives/hikes.
Do you have a particular interest? Do you prefer desert, mountains, forests...etc? Deserts...aside from Death Valley the Mojave National Preserve and Joshua Tree National Park are pretty cool, but there are deserts closer to you (Texas). Okefenokee Swamp Park, Georgia is also super.
Closer to you is Palo Duro Canyon...2nd larges canyon in the USA. You can camp, stay in cabins or day trip. Even the toughest trail isn't that bad.
I have to stop now or I will kill you with my verbose love of all of our (USA) parklands...and then there is Vancouver Island and British Columbia in Canada.
