An interactive trek up Mount Everest

The '7 Summits' is a challenge featuring every continent's highest peak

Some devoted mountaineers aim to tackle the seven highest summits in the world: Mount Everest (Asia), Aconcagua (South America), Mount McKinley (North America), Mount Kilimanjaro (Africa), Mount Elbrus (Europe), Mount Vinson (Antarctica), and either Mount Kosciuszko or the Carstensz Pyramid (Oceania).
