A hammock filter would be an excellent idea.

Adding a filter for hammocking would be such a great feature, and could boost interest and awareness that hammocking is an available option. If it becomes more sought after, more campsites might offer this and even plant more trees to accommodate it in the future, so really, it will be saving the planet!

A lot of campers who prefer hammocks find it hard to find a campsite on pitch up.
Adding the option for sites with this available would make a huge difference.
Surely it’s a matter of an additional box to tick?

Add a filter to the website that shows campsites that have hammocks available or allow people to hang hammocks on their site.

List sites where trees are available for hammock and bivvy camping is possible
