Ursus Cove is a coastal feature on the west side of Cook Inlet, Alaska, within the Kamishak district. It is a broad, open bay approximately five miles wide at its mouth. The coastline is characterized by irregular soundings, and reefs extend up to half a mile offshore, creating a significant navigational hazard for boaters and paddlers. The area is exposed to the full fetch of Cook Inlet, making it susceptible to strong winds and building seas, as historical accounts note vessels being forced to beach due to gales. Tides in upper Cook Inlet are extreme, with vast mudflats exposed at low tide; timing travel to avoid being caught by a rising tide is a critical safety consideration.

The cove is a remote, wilderness location with no indicated facilities, launches, or amenities for paddlers. Access would likely require a skilled, self-supported expedition with careful planning for open-water crossings and variable weather. The area is known for commercial fishing activity and as a bear-hunting location, indicating the potential for encounters with brown bears along the shoreline. Wildlife observations from a packrafting trip noted ground squirrels within the cove. The surrounding geology includes limestone formations that have yielded fossils. The overall character is that of a raw, exposed Alaskan coastline where paddling is a serious undertaking dominated by logistical challenges, tidal timing, and weather windows rather than casual recreation.
