Loomis, Washington

The Washington-British Columbia border is full of tiny towns and Loomis is one of the smallest and more unknown of the lot. Located in the Sinlahekin Valley, Loomis has access to the Similkameen River and the northeastern quadrant of the North Cascades. A nearby highlight is Thirtymile Ridge, a trail frequented by hikers and backpackers that you could probably venture a guess as to the length. There is a fun Class 2 float trip on the Similkameen for canoes or inflatable kayaks – a classic, yet seldom traveled overnighter. If you are exploring Washington’s border towns, Loomis is definitely on the list.
