Big Glory Bay is a coastal bay on the eastern side of Stewart Island/Rakiura in the Southland region of New Zealand. It is a significant location for aquaculture, hosting one of the world's most southern salmon farms. The bay's waters are part of a broader coastal environment that includes notable nearby features such as Ulva Island, a native bird sanctuary, and Whenua Hou Island, a protected breeding area for the rare kākāpō parrot. For paddlers, a primary access point is the South Big Glory Campsite, located on the bay's eastern shore. The bay's character is defined by its remote and pristine setting within the Rakiura National Park, offering views of coastal forests and golden sand beaches like those found at Mason's Bay to the west. The presence of active aquaculture farms means paddlers should anticipate boat traffic and infrastructure related to salmon farming operations. The general area, including the coast of Rakiura and its offshore islands, is recognized for its ecological value, with certain waters near the coast receiving specific protections, though Big Glory Bay itself is an exception to a 5 km coastal protection zone. Water quality is managed with biosecurity in mind, as equipment for the farms is cleaned and sterilized before being shipped into the bay.
