How to Find Parks?

There are numerous apps
RVParky
Ultimate campgrounds
www.recreation.gov
If you are eligible, www.militarycampgrounds.us
try the app store, google or apple, you will find many.

Or simply use google maps, select an area, town and add campgrounds/rv parks near xxxx.

RV Trip Wizard RVTW which is a planning tool has many thousands of parks and is linked to Campground Reviews which has all of those parks listed usually with reviews and pricing.

Campground Reviews

Those are mainly for commercial and park campgrounds not boondocking sites which is a whole different matter.

Mostly googling.

Campendium.com is pretty good.

If we are on the move, we use Passport America for the savings more than finding. PPA isn't as good when staying somewhere more than a night or two (we'll still check but usually they have limits)

We are traveling longer term mostly, so we are quite flexible on where we stop. If it was a week or two vacation, we would place more emphasis on prime location as you have limited time, so driving from a 1/2 hour away to see a national park or other site may be less acceptable and in the big picture represent a small portion of the trip cost.

I have been using RV Life Campground Reviews for years. I like it as not only can you find the place it also gives many years of reviews for the campground you are looking at

https://campgrounds.rvlife.com/

The others out there are good also rvparky was mentioned. Good Sam also has a sight. I think once you find a sight you like and is user friendly to you, you will stick with that sight.

Good Luck

Welcome to the forum

As mentioned, https://campgrounds.rvlife.com is our 1st go to site. Large member/data base on reviews and useful links on the review home pages.

I will also use google reviews for comparisons.

You will find that combining multiple sites is better than just relying on a single site. For planning I use Good Sam and Coast to Coast and Passport America to find destinations. On the road I like RVPARKY because of the real time GPS locates where you are and identifies campgrounds nearby and on the route. I only make reservations at destinations and never for overnight stops. We start looking on RVPARKY around 2 or 3 pm for a CG on our route to be off the road by 4 or 5pm. The app gives all pertinent information to call to check availability and have one held for you. It also has filters for military campgrounds, gas stations, Cracker Barrel, Cabella's etc. It's free to download and I find it easy to use.

State Parks

Also, I'd endorse Campendium, The Dyrt, COE Parks

There's a ton of info in individual state travel guides on the internet, just surf through & see what interests you. Good luck!

Go to Google and type in campgrounds. It will show a map. Click on the map and move it with your curser to an area you want to stay at. You can enter RV parks, State parks if you want to be more selective in your stays. Do the same if you only want to see whats in a certain State.
All the CG's will show up and just click on the ones you like and go to the website listed when the page pops up.
