I use RV Trip Wizard - which is a pay service

or for free Allstays

I also use google maps....whatever area I'm stopping in, or my destination, I search "rv parks", or "campgrounds", etc.

From there, I click on them, read reviews, and usually can go to street view and see sites, the campsites, etc. (not always).

Yes, my google maps method is more manual, but I feel I get a good sense of the park, area, reviews, restaurants, things to see, etc.

Just my 2 cents

I didn't see Campendium mentioned. That's been my favorite for a while.

If you're taking a long trip, RV Trip Wizard is totally worth the price. I used it for planning & tracking an 11,000 mile trip and it was worth every penny.

Tried a number of them and I always go back to Allstays for it's complete listings and map options.
Allstays campgrounds

I prefer uscampgrounds. Gives you some good links, but have to watch their coordinates.

Just go to the top of this page where it says RV Parks. It's free and it works. Better yet, get the app on your phone for a 'map view'.

Same here, it's a great resource.

Another good one is thedyrt.com

https://www.ultimatecampgrounds.com/index.php/products/full-map is excellent as well.
