Juneau is Alaska's capital, and you can reach it only by sea or air. It sits between steep coastal mountains and the Inside Passage, within reach of whale watching, glacier hikes, and float-plane trips. The Mendenhall Glacier is just 12 miles from downtown, one of the easier glaciers in the world to reach on a port day.

This is one of the most popular months to visit Juneau, so book shore excursions early. The top snorkeling spots and tours sell out fast. Dress in layers: a waterproof shell over a mid-layer handles the range between cool mornings and afternoon port temps.
