Part of the Geyser region, the easy to walk Fountain Paint Pot Nature Trail ranks among my family’s favorite paths for its colorfulness. Various algae and bacteria surround the muddy pools of these thermal springs and small geysers, turning the waters pastel green, blue and pink — hence the walk’s name. Allow at least 30 minutes.
Another easy walk even for young children is the Midway Geyser Basin trail, a half-mile loop that leads you past the Excelsior geyser and the Grand Prismatic spring. With older kids and teens, try the 2.4-mile roundtrip Mystic Falls trail through a pine forest and along a creek to the 70-foot Mystic Falls. Sometimes Rangers lead hikes to Mystic Falls.
