We were hosting a couple friends from San Francisco for the weekend, and had promised them an easy hike -- just enough physical activity to justify soaking our bones in hot springs later in the evening. Rainbow Lake came recommended as a simple five-mile hike, just outside Cascade.
Wearied by the three-day journey across America, we kept close to Cascade during our first week in Idaho. Not a problem, since there is plenty to see. The day after our loop around Lake Cascade, we drove up to the summit of Snowbank Mountain and completed a short hike to Blue Lake, tucked away in the hills of the Boise National Forest.
