Location of Arch House Guest House Tullyhona is easy to locate for the first time visitor. Perhaps the simplest route is through Enniskillen. Follow the A4 (Sligo Road) for 2 1/2 miles and branching off on the A32 (Swanlinbar road). From this point follow signs for the Marble Arch Caves. Turn right at posting for National Trust Property at Florencecourt. We also have a sign at this point. Arch House is 2 miles on this road and is on the right, sign posted.
