Whether you want to glamp on a cliff above the ocean or sleep in a tent deep in the forest, camping helps you get away from it all. But one of the hardest parts of camping—wherever you like to be—is finding that perfect campground. The most popular campsites near metro areas or in picturesque national parks can book up months in advance, and there’s nothing worse than pulling up to your destination only to find the campground full.

Luckily, a new crop of websites and apps makes finding and booking a campsite easier than ever. For instance, if you’re looking for a campsite in one of the famous national parks, Reserve America might be your best bet. It’s one of the largest online campsite systems, and it’s super easy to find quality campsites based on your needs.

Should you be looking to get off the beaten path, then Boondocking could be perfect for you. Designed as a guide to dispersed camping—places with few amenities and off-the-grid camping—Boondocking.com is a public forum database where you can search for free, auto-accessible camping spots using latitude and longitude. The easy-to-use app shows crowd-sourced information about where people have successfully camped with directions and varying degrees of detail.
