 Small cruise-ships (up to 250 passengers) and private yachts visit from May through September.Petersburg has a high-quality visitor experience, with very few of the crowds or tourist peaks experienced by the neighboring communities of Juneau, Sitka and Ketchikan.Partially this is by design and partially this is a result of the natural difficulty of landing large ships in Petersburg and traveling through the treacherous waters south of town at the Wrangell Narrows.
