As Tammy and I planned our walks for this trip to the island of Kauai, we carefully considered how much the repaired Achilles and all of the OTHER muscles, tendons, joints and bones required to hike could take. We both agreed that the Kuilau Ridge Trail was a reasonable and realistic goal and we would be disappointed if we did not manage it. The Canyon Trail and the hike to the top of Waipo'o Falls, on the other hand, was purely aspirational.
