I-65 South Take Exit 48. Turn west on 255, towards Mammoth Cave. The first part of your drive is approximately 2 1/2 miles and leads past Diamond Caverns, then ends at Mammoth Cave road (highway 70). Turn left at the stop sign, following the sign to Brownsville. This part of the drive is also approximately 2 1/2 miles, and goes past a nice pond that you can walk around called Sloan's Pond Walk. Turn left again, continuing to follow the signs to Brownsville, approximately 6 miles. This final part of the drive leads past a nice 1/2 mile walking trail called Turn Hole Bend trail. Serenity Hill Bed and Breakfast will be on the right, approximately 1 mile past the park. Look for our sign then make a sharp right hand turn up the hill. Be sure to watch for the local natural pedestrians (deer, turkey and other wild life).
