Rýchory constitutes the easternmost part of the Krkonoše Mountains National Park and thanks to their highly valuable botanical locations, the upper parts around the main ridge of Rýchory have been included in Zones I and II of the national park. The Dvorský les forest in Rýchory preserves a remaining area of beech primeval forest, consisting of the bizarre trunks of old beech, rowan, birch and spruce trees covered with moss and is a favourite location of nature photographers.
