The Andernach Geyser Nature Reserve features Europe's highest cold-water geyser set on the Rhine River bank, offering visitors dramatic natural eruptions and diverse riverside ecosystems.
Located near the town of Andernach in Rhineland-Palatinate, Germany, the Andernach Geyser Nature Reserve protects a unique geological and ecological site centered around the Andernach cold-water geyser, the tallest of its kind in the world. The geyser blasts up to 60 meters (197 feet) high, powered not by volcanic heat but by carbon dioxide gas escaping from underground volcanic fissures in the volcanic Eifel region. The reserve encompasses surrounding wetlands, meadows, and limestone cliffs along the Rhine River that support a variety of flora and fauna, including rare and protected species. Originally recognized for its volcanic activity and water chemistry, the site was designated a protected nature reserve to preserve this rare natural phenomenon and its habitat. Visitors to the reserve can enjoy boat tours to observe the geyser eruption, hiking trails along the Rhine floodplains, and educational exhibits about the geological and ecological significance of the site. The landscape offers opportunities for birdwatching, photography, and experiencing the interplay of volcanic geology with river ecosystems. The nature reserve balances visitor engagement with conservation, providing guided tours that explain the geyser’s mechanics and local biodiversity. Proximity to the town of Andernach allows easy access for day visitors interested in outdoor recreation combined with geological wonder. The reserve serves as a notable attraction in the Rhineland-Palatinate region, drawing nature enthusiasts and scientists alike.
