There are about 1,500 volcanoes on land — and even more underwater — but only one that you can truly climb inside.

An adventure to fill the spirit

The Grand Canyon is the second most popular national park. More than 4 million people visit each year. So it's a little surprising there's any place where you can have part of the rim to yourself.

It's called Toroweap. Or Tuweep. The national park guide doesn't appear to take sides.
