County Roscommon at its highest
Roscommon's county high point is a slope location on Seltannasaggart, rather than the mountain's main summit. High Point Ireland lists the southeast slope at 412m, making the county boundary central to this particular challenge. A summit name alone is therefore insufficient when comparing sources or saving a map pin. This entry rewards careful geographic research: you are seeking the highest ground inside Roscommon, which need not be the highest ground on the whole mountain.
Before you go
Plan your visit
Identify the southeast-slope location, G904196, on a current detailed map and check how the county boundary crosses the mountain. High Point Ireland recommends Discovery Sheet 26 or OSNI Discoverer Sheet 26. Neither the grid reference nor the list entry provides a walking route. Current approach and land-access arrangements were not independently verified for this profile; confirm them locally and avoid assuming that tracks or infrastructure on mapping are open for public use.
