Sumbawa, the large volcanic island in the province of Nusa Tenggara Barat in central Indonesia, is situated between Lombok and Flores in the Lesser Sunda Islands, its rugged volcanic landscape including the caldera of Mount Tambora — the site of the 1815 eruption that was the most powerful volcanic event in recorded history, killing approximately 70,000 people and causing the 'Year Without a Summer' in 1816 across the Northern Hemisphere. Semolon Hot Spring Sumbawa draws on sodium-rich sulfurous geothermal waters from the active volcanic geology of the Sumbawa volcanic chain, emerging at temperatures around 55 degrees Celsius to create therapeutic outdoor pools set in the wild landscape of the Sumbawa highlands near the Semolon village community. The Mount Tambora caldera and volcanic heritage, the extraordinary surf breaks of the Sumbawa coast attracting international surfing enthusiasts to waves considered among the best in Southeast Asia, and the traditional Samawa and Bima kingdoms whose cultural heritage is preserved in the island's royal palaces and traditional textiles make Sumbawa a dramatically volcanic and culturally rich hot spring destination in the Indonesian archipelago.
