The Río Moat is a waterway in Tierra del Fuego, Argentina, offering a paddling route that leads from the river out to the coastal waters of Cabo San Pío. A primary access point for beginning a journey is from the Prefectura (coast guard) post located at the Estancia Moat, which is reachable by vehicle from Ushuaia. This route is suitable for a multi-day kayak expedition, traversing from the river through to the open sea. The surrounding landscape is part of the remote and rugged Tierra del Fuego region, characterized by its southern Patagonian environment. Paddlers should be prepared for a wilderness experience with significant exposure to coastal weather and sea conditions once beyond the river mouth. The presence of a Prefectura post at the put-in suggests an official point of contact, but specific regulations or required permissions for paddling are not detailed. Facilities directly at the access point appear to be minimal, limited to the official post. The route connects inland waters with the dramatic coastline near Cabo San Pío, indicating that paddlers will encounter both riverine and marine environments, with the associated wildlife and scenic vistas typical of this southernmost part of Argentina.
