Marmot Bay is a coastal bay on the Pacific Ocean near Kodiak Island, Alaska, offering paddlers access to a rugged wilderness setting. The primary known public access point for paddlers is the Anton Larson boat ramp, which provides direct entry into Sharatin Bay, a part of the larger Marmot Bay system. This launch is a concrete boat ramp with an adjacent parking lot, suitable for launching kayaks, canoes, and stand-up paddleboards. The area is a sheltered ocean environment with significant tidal influence, requiring paddlers to time their trips around slack tide for the easiest conditions. The bay is exposed to open water and can experience challenging conditions; a reported marine accident describes conditions with 20 mph winds and 10-foot seas, underscoring the potential for severe weather that can rapidly diminish visibility and create hazardous waves. The best time for paddling is during the summer months, from June through August. The surrounding area is characterized by Alaska's vast wilderness, offering solitude and natural scenery. Cell phone service in the area is limited, and paddlers are strongly advised to carry a marine VHF radio, practice self-rescue techniques, and never paddle alone in these open ocean conditions. More experienced paddlers can find opportunities for coastal exploration and sea kayaking journeys from this launch point.
