Sulphur, OK is known as the gateway to the Chickasaw National Recreation Area (the country's 7th oldest National Park) and is tucked away between Oklahoma City and the Dallas metroplex, located just off of I-35. Native Americans referred to the area for centuries as "the land of rippling waters." Today, Sulphur is proudly called the "City of Springs." Experience a daily ranger-led program at The Travertine Nature Center, or catch a glimpse of Sulphur's rich history at the Arbuckle Historical Society Museum. Meander through the Historic Main Street District, and take time to relax and pamper yourself at the New Beginnings Day Spa or Echo Canyon Spa & Resort.
