When going to a campground I haven't been to before I like to look at photos of available options to avoide any surprises upon arival. Since photos are not always available through booking services, I use these guys:
Oh wow this is awesome! I'm going to a new place in a few weeks and looked it up to check it out. Amazing that it has pictures of each site. Thanks for sharing!
I like to use Camping Project through REI to help search for campsites. It has a good amount of campground information, but also lists out trails and climbing nearby-- all in one place! I would check it out if you get a chance! https://www.rei.com/campgrounds
