The Huckleberry is one of the best and easiest to gather berries in the mountains. At least if it grows in your area. It doesn't generally grow in my area, but on a recent trip to Montana, I was able to find and enjoy handfuls of huckleberries for lunch on one of my hikes.

Lolo National Forest has a good foraging policy, for example, "a permit is not required for recreational huckleberry picking up to 10 gallons per season."

The taste of huckleberries does not need much explanation. They are much like blueberries, but somewhat tarter. The great thing is that they grow in large quantities in fields of bushes, so one can easily pick a lot without much effort. Some people use a berry rake to make it even faster, but compared to searching for strawberries, even hand-picking huckleberries seems effortless. You can easily pick a handful in a minute, and a pie-full in a short time.
