This route is part of leg 8 of my world tour. Impressions can be found here https://forums.flightsimulator.com/t/exploring-the-world-in-the-beechcraft-bonanza/266981/12?u=svenz

The route starts in the North-West at Belmullet Aerodrome, a smaller plane is required to take off from here. You'll fly over Ballycroy national park to Connemara. Then Mount Shannon and Limerick to reach Kerry. From there I added a couple gps waypoints to go along Killarney National park, Carauntoehill, Knockroe bog and Bonane Heritage Park to Cork. From there a couple more small airports to end in Dublin after navigating over the Wicklow mountains.
