I booked the 5 day Havasupai Falls trip with AOA on May 17th. This was definitely the best organized, best guided hiking trip I have ever been on. The guides, Kevin and Jason were absolutely fabulous in every way - from knowledge of area, participant care, meal preparation, and communication skills - most of all they were just plain fun!! Overall fabulous trip and I will definitely book another trip with AOA and recommend them to others!!
