Expeditions are longer tours and these are the trips where the line between the guests and the crew are thin. Expedition trips pose challenge and reasonably reward one with the joy of accomplishment. Expedition trips may require the participants to rough it out and one needs to display high team player spirits. Personal fitness and strong will, would also be desirable. Expeditions build a strong sense of comradeship among the team members, and it is often that this inter personal bonding carries on for times to come.
