The Tunnel Hill State Trail is a bicycle trail running from Eldorado to Karnak, Illinois. The trail runs along the former bed of a part of the Cairo and Vincennes Railroad, a transportation unit led during its early years by Civil War General Ambrose Burnside. The Cairo & Vincennes became a branch line of the Southern Railway before its trail section shut down in the late 1900s. The northeast end of the trail is in Eldorado, on Trolley Road just north of U.S. Route 45. The southwest end of the trail is west of Karnak just off Illinois Route 37. The trail connects to several trails including the River to River Trail; the Illinois southern route of the American Discovery Trail; the U.S. Bicycle Route 76; and the Trail of Tears National Historic Trail. The trail is 45 miles long. The trail is suitable for both hiking and bicycling. The trail surface is crushed limestone. During the summer, the surface is hard packed and easily ridden on a road bicycle. However, at other times of the year, the trail may be soft and is better navigated on a mountain bike or hybrid. Parking is available at several locations. However, full services are only available in Harrisburg and Vienna.

Another interesting location in Vienna that is within drivable distance from Hotel 7 Inn is the Reynold J.W. Rock of Ages Memorial company. J.W. Reynolds was founded by John Wesley Reynolds, along with his family in 1888. They are known for being leading manufacturers and retailers of granite memorials throughout Southern Illinois. Rock of Ages is a quarrying company that was started in 1885. When these two companies merged, they became the only business in the area to quarry, manufacture, sell, and set their own memorials.
