If you've ever felt the stress of navigating a busy airport terminal, imagine turning a corner and finding a six-foot-tall llama dressed as a pirate waiting to greet you. That scene is a regular reality at Portland International Airport, where therapy llamas and alpacas visit about once a month as part of an animal-assisted therapy program that launched in 2023. The animals come from Mountain Peaks Therapy Llamas and Alpacas, a nonprofit based in Ridgefield, Washington, and their mission is simple: help travelers relax.
