searching wooCommerce calendar for bookings

I’m searching for days now but couln’t find the right solution/plugin.

I have a website and people can book sightseeing trips there.
There should be a calendar with available tours (marked as green or something) and a field to specify the amount of people.

But I can’t find a easy solution to integrate the calendar.
It should be easy to add multiple available days / ranges.

Like here (Screenshot):

Any suggestions?

Thanks!
