There are four stables to choose from on Kauai , one in Poipu, one in Wailua, and two in the Princeville area. Rides range from a one and a half hour country ride to a four hour ride to a waterfall for lunch and a swim. Most of the stables limit riders to walking, and one allows trotting and cantoring for experienced riders.
Private rides are also available.
One stable even offers a cattle drive. No discount for kids, and they do have age requirements.
