Local Tour Guide for Castlerea and Surrounding Roscommon Areas

Looking for a knowledgeable local guide to show a small group (4 people) around Castlerea and key historical sites in County Roscommon. We're interested in local history, heritage, and perhaps some lesser-known spots. Would need a half-day tour (approx. 4 hours) on a weekend in the coming month. Please provide details on your experience, typical itinerary suggestions, and availability.
