Walking Tree was founded by three childhood friends who, through extensive time abroad, have come to share a love and respect for the transformative power of travel and cultural exploration. Since our inception, Walking Tree has grown into a team of exceptional, like-minded individuals who help to share this passion during our unforgettable programs. Take a look at who we are!
