At Thunder River Farm, you will find the highest quality animals. We have some of the industrys most desirable bloodlines.

We are involved in every aspect of the alpaca and yak industry including breeding, stud service, boarding, sales, financing, meat, fiber and clothing and accessories. Visit our farm store for a wide selection of yak and alpaca clothing and accessories.

Our goal is to help you understand the alpaca and yak businesses.

When you purchase animals from us, we will help you with farm layout, pasture management, herd health knowledge, training, showing, birthing, medications, what products you need to get started, parasite control, harvesting the fleece, etc.

As ambassadors for the alpaca and yak industries, we are members of the Alpaca Owners Association, the Suri Network, the Alpaca Registry, the Pennsylvania Alpaca Owners and Breeders Association, the Mid-Atlantic Alpaca Association and the International Yak Association.
