World's Premier Geothermal National Parks

Home to over half of the world's geysers, including the iconic Old Faithful. Visitors can witness a vast array of hydrothermal features such as boiling mud pots, fumaroles, and colorful hot springs across three distinct volcanic calderas.

Located in New Zealand's Taupo Volcanic Zone, this area features the only geyser in the Southern Hemisphere. It offers a dense concentration of steaming vents, acidic lakes, and geothermal power stations showcasing industrial geothermal use.

While part of Yellowstone, this specific site deserves mention for holding the largest hot spring in the US. The vivid microbial mats create a rainbow effect visible from overhead, offering a unique visual contrast to the surrounding pine forests.

Although primarily known for its deep blue caldera lake, the park contains significant geothermal history and nearby features like Obsidian Cliff. The volcanic origins of the area provide insights into past explosive eruptions that shaped the landscape.

While famous for its quartz-sandstone pillars, this park in China exhibits some geothermal activity in the form of hot springs used for medicinal bathing. The combination of dramatic geology and thermal waters creates a unique recreational experience.

Located in Hawaii, this park features the dormant Haleakalā volcano which still emits steam and sulfur gases. The high-altitude desert landscape is punctuated by geothermal vents, offering a starkly different geothermal experience compared to wetter regions.

In Indonesia, the broader volcanic region offers access to natural hot springs and geysers fed by the nearby active stratovolcanoes. The area is a hotspot for observing active tectonic processes and associated thermal features in a tropical setting.

This UNESCO site features a constantly erupting volcano with nearby geothermal vents. Visitors can explore hiking trails that lead close to fumaroles and hot springs, providing a rare opportunity to observe active magmatic degassing up close.

New Zealand's first national park is home to the stunning Blue Lake and several active craters emitting steam and sulfur. The volcanic landscape offers some of the most accessible geothermal hikes, including the famous Tongariro Alpine Crossing.

Located in Indonesia, this park features a massive caldera containing Segara Anak Lake, which has its own geothermal hot springs within the crater. The active volcano provides a dramatic backdrop for trekkers seeking high-altitude thermal features.

Famous for its acidic blue flames caused by burning sulfur gases, this geothermal site in Indonesia is a unique natural phenomenon. Miners work here daily, and visitors can see the intense geothermal activity that powers the area's sulfur deposits.

Near Rotorua, this dedicated geothermal park showcases a rotating cast of geysers, mud pools, and colored lakes. The Champagne Pool is a highlight, known for its bright yellow and orange colors caused by iron oxide precipitates.

Located in Iceland's High Lands, this area features steaming fumaroles and hot springs in a stark, otherworldly landscape. It is a key part of the geothermal circuit, offering raw, unfiltered volcanic activity far from tourist crowds.

Another Icelandic gem, Hverir is a massive mud-pot field with boiling springs and constant steam vents. The landscape changes rapidly due to frequent minor eruptions, providing a dynamic glimpse into future volcanic terrain.

While a commercial facility, the Blue Lagoon in Iceland is fed by the Svartsengi geothermal power plant. It showcases the interaction between industrial geothermal energy and natural mineral-rich waters, creating a unique milky-blue hot spring experience.

This relatively new park in Iceland gained fame for its recent lava flows. While primarily a volcanic hiking site, it offers access to surrounding geothermal areas and showcases the ongoing construction of new land through fissure eruptions.

Located on the Reykjanes Peninsula, this area features the geothermal power plant at Svartsengi and surrounding natural vents. It is the site of recent volcanic activity, making it a critical location for observing real-time geothermal and tectonic shifts.

A lesser-known but equally impressive area in Yellowstone, this park features a large acidic lake and numerous fumaroles. It offers a quieter, more rugged geothermal experience away from the main boardwalk crowds of Old Faithful.

Distinct from the colorful hot springs of Yellowstone, these are formed by calcium carbonate deposits from the cold spring. The terraces resemble marble cliffs and change constantly, offering a unique geological process driven by geothermal heat.

The hottest and most dynamic geyser basin in Yellowstone, Norris features steamboat geysers that erupt unpredictably. Its acidic environment supports unique thermophilic bacteria, creating vibrant colors and constantly changing thermal features.

Located in New Mexico, this preserve contains a massive volcanic caldera with active geothermal systems. It features hot springs and fumaroles that support diverse ecosystems, offering insights into large-scale volcanic collapse and resurgent dome formation.
