The passage between Pleasant Island and the mainland provides a satisfactory fair weather anchorage and is a useful spot to anchor overnight if you need to sail into the Glacier Bay Visitor Centre in time for a mandatory 0800 orientation session the following morning. 

In westerly winds anchor just to the east of the marked spit on the north side of Pleasant Island in 5-6m of water. Good holding in mixed kelp and thick mud. In winds with a northerly component you can anchor just off Gustavus,  clear of the ferry berth and the moorings used by local fishing boats.

Both anchorages offer better shelter than the chart would suggest and are commonly used by local fishing boats.

If the weather is fine the view from the anchorage of the snow capped peaks in Glacier Bay is stunning and arguably better than the views from within the Bay itself where the views of the high peaks are often obscured by lower hills in the near foreground.
