What is the ideal group size to enjoy the trail, the most?
A group should not be so large that it breaks into sub-groups. At the same time there should be enough participants to share the load and responsibilities. Ideally smaller groups tend to walk together and enjoy every bit of the trail. A lot is determined by the nature of the individuals forming the group. Discourage intoxicants and loose characters, as they spoil the fun and the environment and are often cause anxiety.
