Kayaking is one of the best ways to enjoy Posey Island. Paddle around Spieden Island and watch antelope and long-horned sheep grazing on the meadows. Keep an eye out for orca whales, seals and porpoises that are often spotted in these waters. Posey Island is a popular stop for commercial kayak tours and can get busy during the summer.
