Golfo Nuevo is a large coastal bay on the Atlantic coast of Chubut, Argentina, forming part of the Península Valdés region. The bay's waters are known for their high transparency in areas like Bahía Pardelas. Primary launch points for paddlers are from the city of Puerto Madryn and the village of Puerto Pirámides, where guided tours typically begin. The overall character of paddling here is defined by wildlife observation, with southern right whales present from approximately June through November, particularly concentrated inside the bay. During this whale season, strict regulations govern all navigation; kayaking is exclusively coastal, and no active approach to whales is permitted, with observation conducted from a respectful distance to avoid altering their natural behavior. Other notable wildlife includes sea lions, observable near Punta Loma, and various seabirds. The bay is also subject to harmful algal blooms known as red tide, which have caused marine mortality events. Guided tours emphasize stable kayaks and are conducted only in favorable weather conditions, suggesting wind exposure is a significant consideration. A recommended day trip involves a 12-kilometer coastal paddle from Puerto Pirámides to Bahía Pardelas, exploring caves and cliffs, with the option to return by kayak or by trekking along the shoreline. The water can be cold even in summer, necessitating appropriate layering. The aesthetic is one of stark Patagonian coastline meeting a rich marine ecosystem, with the dramatic sight of whales sometimes visible close to shore from beaches like El Doradillo.
