FANCY following in the footsteps of Sir Edmund Hillary, who scaled Everest on 29 May, 1953? Joining an expedition is easy.
Adventure-tour companies organise treks just as tough as those undertaken by professional explorers, while holidaymakers are increasingly joining scientists in the field to monitor humpback whales off Australia or dig for Etruscan remains in Italy.
Today's expeditions are unlikely to tread virgin soil.
Instead, they satisfy personal goals or help with conservation or community projects.
Some even raise funds for charities. But who goes? Everyone from pop stars to politicians, financiers to factory workers, teachers to taxi drivers. Any age from students to grandmothers. Some travel solo, others in couples or as groups of friends.
Raleigh International's trips, such as the one Prince William joined in Chile, are geared towards ages 17 to 25 but 70-year-olds have participated in Worldwide Journeys' charity expeditions (being fit helps).
Flights, accommodation and meals are included along with local guiding, team leaders and overseas medical support.
New friends are guaranteed.
Just do it.
