I was confused before I left with Gapforce what I was involved in. I quickly learned GapForce is a booking agent for programs with GreenLion and that GreenLion has tons of adventure and volunteer programs in lots of counties. You can book as many as you want for however long you want and even take weeks off for your own adventures. A program called a road trip is offered in many countries which in some countries means constantly moving and sightseeing and in other countries like Nepal means you are signed up for an intro week, adventure week, trekking week, and volunteering week. You have a home base at a volunteer house and each week head to different projects, some in different cities that you stay at a site there and some close by to the volunteer house so you stay at the volunteer center for the week. You can extend your stay even after you are there. Don't be afraid to change your schedule, go on your own in free time, and book what you want on weekends.
I never thought I'd be bathing in a river with elephants but it was the coolest experience and I never would have found it without GapForce. Although I felt I didn't know too much before leaving, GapForce was always super available to me during my travels and coordinated shipping packages for me and sending more info and still was available for questions. I had so many adventures from preparing food for Gibbons and elephants and feeding them to staying with an Akha host family in Chiang Rai. Great experiences!
