Secret Bay is located within the Beardslee Islands of Glacier Bay, Alaska, USA. It is a coastal saltwater bay accessed via the Beardslee Entrance, with access being highly tide-dependent. Paddlers must plan their arrival to coincide with a low-slack tide to enter the bay, as one specific itinerary notes entry was made at 4:30 pm during a low-slack period. The bay itself is a very good camping location, though paddlers are advised to bring all fresh water with them as none is available at the site. The surrounding area offers exploration of the Beardslee Islands, with routes passing landmarks like Kidney Island. The paddling character is defined by significant tidal currents in the connecting channels, requiring careful timing. A crossing of the nearby Sitakady Narrows, for example, must be planned for low-slack tide to manage currents. The environment is remote wilderness, with camping on gravel beaches and notable wildlife such as salmon in nearby streams. There are no facilities or amenities directly at Secret Bay; all trips require self-sufficiency and adherence to National Park Service regulations for Glacier Bay National Park, including mandatory briefings for kayakers.
