Locate a company that offers zip line adventure tours in the area where you live or will be vacationing. Websites such as ziplinenirvana.com and ziplinedirectory.com have comprehensive lists of companies around the world. Calling the local visitor's bureau or using a concierge service also provide options for locating companies.
Read the information about the zip line adventure you're selecting. Familiarize yourself with what they offer. Some zip line tours last as long as 6 hours, while others last less than an hour. Companies might offer one specific tour or give adventurers a choice of different tours.
Check the weight limit. Many tours impose a weight limit for both a minimum and maximum weights for safety reasons. Make sure that no one in your party is under or exceeds the limit.
Make a reservation for your tour. While not all companies require this, it's best to make one to ensure your zipping adventure will happen. Be prepared to pay a down payment when making your reservations. While not all companies require this, you might need to offer your credit card number in order to hold your spot.
Show up at the time designated by the company. Your tour likely will include a safety orientation and gear fitting, which are vital to proceed with your adventure.
Wear closed-toe shoes such as sneakers or hiking boots. Wear long pants or shorts with a long inseam. Skirts, dresses or short shorts make it hard to properly fit your harness. Bring a beverage in an unbreakable plastic container with a clip-on strap to hold it in place.
Use the bathroom before beginning your zip line adventure. You'll be fitted with a harness that makes using the restroom a hassle. You might not have access to a bathroom for the length of your tour.
