Check out this airport where they land on the beach

There's just one airport in the entire world where your official runway is a beach, and it's Scotland's Barra Airport.   Check out their website that even "promises a unique landing experience." 

As noted by AirFareWatchDog.com the facility is "the only one in the world where scheduled flights land on a beach.  When the windsock is flying, locals are advised to keep their distance from its three runways, which are marked by wooden poles.  High tides cover them, so flights must be scheduled accordingly.  For bonus chills and thrills, fly in at dusk, when just a few vehicles are used to illuminate the runway."
