6. Eurwangni Beach
It may only be minutes from the ultra-busy Incheon Airport, but Eurwangni is a beautiful crescent with shallow water perfect for paddling. When the tide washes out, clams, crabs and trumpet shells appear from the mudflats; no surprise, then, that there are plenty of seafood shacks — ideal for preflight shellfish snarfing. It’s popular with Seoul day trippers, too, hoping to catch a spectacular sunset.
