Our group consisted of about ten guests and two tour guides. The ride is somewhat more difficult than a standard trail ride mostly due to several steep inclines and downgrades through rough terrain. That being said, several riders were first time horseback riders and they encountered no difficulties - other than the standard problem of keeping the horses on the trail and stopping them from eating the brush and other foliage along the way.
Our guides asked for an experienced rider to ride on one larger horse - someone with a strong hand. Lacking any other volunteers, I raised my hand. Interestingly, this larger horse made for a smoother ride and he got into much less trouble than some of the smaller horses that always wanted to leave the trail.
