Knoxville, Tennessee, surrounded by the rolling hills and rivers of the Appalachian foothills, is a hotspot for outdoor adventures—but snorkeling tours are not part of this landscape’s offerings. The waterways here push with currents more suited for kayaking or fishing than underwater exploration required for snorkeling. Freshwater snorkeling tours, which depend on clear, warm waters with abundant marine life, are simply not available around Knoxville. Between the Tennessee River’s depth and murk, and the lack of saltwater reefs or spring-fed snorkeling spots, opportunities vanish.

Instead, Knoxville shines with other water-based activities like paddleboarding and river rafting, while its trails invite hiking and exploring the nearby Great Smoky Mountains. Visitors looking for underwater aquatic tours will need to look beyond Knoxville to coastal or spring-fed areas more suited for snorkeling.
