Tucked away in the Northwest corner of the United States is one of the country's greatest national treasures: North Cascades National Park. Replete with stunning vistas, lush forests and crystal clear waters, this natural paradise is a great destination for both adventure seekers and the easy-going types. It may not be well-known as a dog-friendly park, but that doesn't mean it doesn't still have quite a bit to offer. Between the recreation areas, roads and Pacific Crest Trail there is plenty to explore, and under the watchful gaze of one of the United States' most gorgeous mountain ranges, it's impossible to ignore the sheer majesty.
North Cascades National Park may not be the MOST dog-friendly park on the list, but it certainly has an absolute ton to offer if you know where to look. Between the gorgeous recreation areas, surrounding Cascades and a sprawling trail that courses through a fair amount of the park (let alone all the way to Mexico!), visitors and their dogs won't likely be disappointed by the endless natural beauty.
