World's largest buffalo roundup (South Dakota)

This ground-shaking spectacle takes place the last Friday of September during the Buffalo Roundup and Arts Festival in Custer State Park, home to the world's largest publicly owned bison herds (there are 1,300 of the beasts).

"It doesn't always go as planned -- the buffalo have a mind of their own," admits the park's buffalo expert, Craig Pugsley.

"You hear a lot of whip cracking, see a lot of arm waving and hear a few screams as the cowboys try to coax the herd into the corrals and a crowd of 14,000 onlookers enjoy a scene from the Old West."

Dog mushing (Yukon, Canada)

A professionally led dog mushing trip is an incredible way to experience the frozen north, and one of the best of them sets out from Whitehorse in Canada's Yukon.

When your team of faithful friends aren't whizzing you across the Yukon's ice plains, you'll sleep in a tent you've erected with your own fair hands.

AFRICA

Serengeti balloon safari (Tanzania)

Seeing the great migration from the back of a jeep is great, but if a dust sandwich doesn't appeal, you can try a hot air balloon.

For $3,520 you can have the entire balloon to yourself and seven friends for an hour, after which you'll enjoy a delicious breakfast in the African bush.

Saharan heli-desert trip (Morocco)

Camel safaris might sound tempting, but after the initial photo op and first five minutes, galloping across the dunes can actually be an uncomfortable, dusty, dehydrating affair.

A helicopter ride over Morocco's dusty expanse is a far more relaxed option.

The price of this package includes one night at the Dar Ahlam Desert Camp, a campsite whose tents have antique dressers, en-suite bathrooms and Persian rugs.

Gorilla tracking (Uganda)

Few things offer a sense of perspective like coming face to face with one of our primate cousins.

This gorilla tracking expedition is led by Dr. Gladys Kalema-Zikusoka, one of the world's top gorilla experts.

The three-night package includes transfers to and from Uganda's Entebbe International Airport, a trek through Bwindi Impenetrable Forest and a visit to a gorilla field research station where you'll have the chance to analyze some fresh gorilla dung.
