Not only were the trees in Fulufjallet National Park in Sweden of interest, but we discovered the extraordinary white lichen and colorful mosses found on the summit surrounding Old Tjikko.  The rocks seemed to have as much to say as the trees and as the lichen grow at about a millimeter every year, some of the lichen covering the rocks is hundreds of years old.  We had a perfect rainy day for our hike, which cleared everyone else off the mountain, so we got to commune with the storm and Sweden's largest waterfall nearby.
