To be honest, the hike up Huckleberry Mountain is pretty dull. For roughly 6 kilometers you'll walk through the forest, steadily climbing but with no views whatsoever. Once the forest finally starts to open up you'll see the massive amounts of huckleberries everywhere (if you time your visit for late summer).
It depends on time of the year, but the whole area can also be pretty hazy due to wildfires, but still worth the visit, the views from the top are fantastic. At the top is almost always someone (not during few days off) who monitor and detect fires.
We've got pretty lucky and had private tour about how all the observation equipment works (from 1910, and apparently no one has managed to invent anything more accurate for locating fires since!), how the lookouts communicate with the other three towers, how they receive supplies, and more. Because we don’t have anything like this in the Czech Republic, we were genuinely fascinated to learn how the whole system operates.
