"Llamas are great hiking companions. They are alert, curious, and just as excited to be in the mountains as we are. They walk at a comfortable pace for hiking humans; and their keen senses of smell, hearing, and sight will often point out a distant herd of deer or elk for us. They have captured our hearts with their unique, "llama-like" behavior and amusing personalities. Their presence makes our time in the wilderness even more memorable."
