There’s nothing in science that says the places where water meets landmass must be captivating to the human observer. Yet so often, it’s the coastlines that we’re drawn to, both as travelers and as inhabitants of the land. Something like half the world population lives within 60km of the sea.
And among the thousands of miles of coast around the world, these are the best of the best. From extraordinary natural features to stunning manmade embellishments, the coastlines depicted in the photos below — both the remote and the well-trafficked — will inspire you to get out there and see them for yourself. 
Rio de Janeiro, Brazil
Famous for Carnaval, Rio sits on Guanabara Bay and is dominated by Sugarloaf Mountain. Carioca beaches are well-maintained and provide an escape from the urbanization and political problems simmering in Rio itself, although many of the older buildings next to the water are being replaced with modern skyscrapers.
