We toured this grove on a sunny day. I read later that it can get quite foggy up there.
It was a different experience than hiking Miner's Ridge, but every bit as pleasant. It was a short and easy hike. If you go, grab a brochure as soon as you cross the bridge and read about the forest as you go. It's very interesting. The area is open and airy, and I imagine it's absolutely gorgeous when the rhododendrons are in bloom.
