Named for the lord of the British Admiralty, Hood Canal—less than 2 miles wide for most of its length—separates the Olympic and Kitsap peninsulas. Clamming is a popular in summer. US 101 hugs the canal’s western shore for more than 30 miles. The conifers begin thinning out, with shoreside communities like Eldon and Lilliwaup basking in peaceful, watery serenity.
