Use the Internet to get information from travel guides; read travel blogs about the places you want to go; chat with travelers who have recently returned from an adventure trip; consult with local authorities; check what travel documents and visas are necessary and book flights and accommodations.
Plan your route carefully making use of reliable maps. Use terrain maps showing elevation, water crossings, mountains etc. Include in your route where you are going to sleep, plan the distance you want to cover in a day and how long will it take to get from resting point to resting point.
Make sure you have money in the local currency as most adventure trips are off the beaten track where Traveler’s Checks or foreign currency will not be accepted. Take some smaller denominations for tips, baksheesh and the occasional bribe!
Get your papers in order including detailed maps, passports, visas, insurance policy, camping or other permits. Carry with you photocopies of your passport and I.D. Don’t forget to take a list of any medical information (allergies, blood type) in case of emergency.
When choosing your adventure destination consider parts of the world that are endangered and unlikely to be around much longer, like Greenland’s Icebergs or areas with endangered species. See them while they still exist.
Perhaps one of the most important items for survival is water. Plan to take water and to know where to find water sources along your route.
Allow for emergency exits, places where you can ditch the trip if something goes wrong. Plan for at least two potential exit points each day where there is access to transport, means of communication or other contact with the world at large.
Plan the food for your adventure trip, consider how much you can carry, what food will last longest, will you have access to places to buy food along the way and how will you prepare the food. Choose foods by how easy they will be to carry and prepare.
Pack light, although you need to pack for all events – wet and dry weather etc. Keep clothes to a minimum, in most cases you can wash some clothing along the route or live in the same jeans for a week!
The necessary equipment for an adventure trip can be expensive but you can buy second-hand, rent or borrow all kinds of specialty equipment and climate specific clothing.
