Follow the beaten path! In thermal areas, boardwalks take you to amazing places, protect the park, and keep you safe. Have you ever wondered what it takes to build a boardwalk in thermal areas? Here’s a behind-the-scenes look on how it’s done! People have been severely burned and killed after leaving the boardwalk or reaching into hot water. Geysers, mud pots, and hot springs are delicate. Don’t throw anything into any hydrothermal features, touch them, or change them in any way. #YellowstonePle
