It seems few people visit this site without getting a soaking or having difficulty finding it. Well the former was true for us, but I think the signage must have improved considerably as we found it fairly easily. It's a bit of a trudge from where we parked next to a waterworks(?) on the main road (why does it always seem to take longer to walk 'to' somewhere rather than 'from'?), but well worth a visit. The tomb stands majestically on a slightly elevated position overlooking the Lough with the Sperrin Mountains as a backdrop. I'm sure it would look even more enigmatic in low Autumnal sunlight on a dry day, but that's for another time.
