Juneau is the only US state capital you cannot drive to. The mountains behind it
are too steep and the icefield above them too big, so everything arrives by boat
or by air, which is also why the cruise dock is a hundred yards from the state
legislature.
It is usually the longest port day of the week, and that is the whole point
of it. A twelve-hour call is enough for a whale-watching boat and the glacier,
which is the standard combination and is standard because it works.
Mendenhall is a drive-up glacier, thirteen miles from the dock, and that
accessibility is the trade: it is busy. The walk to Nugget Falls is flat, paved
and worth doing; the West Glacier Trail on the other side of the lake is a real
hike and is nearly empty by comparison.
Whale watching here is about as reliable as it gets. Auke Bay operators
generally guarantee a sighting between June and August and generally do not have
to honor the guarantee. Boats are small, the water is sheltered, and the
humpbacks are feeding rather than migrating.
Rain gear, not umbrellas. Juneau gets around five feet a year and the wind
off the channel makes an umbrella useless.
