15B Cnoc Corr Guinie
You can park at the forest road off the B9176 at NH653756 and bike all the way to the summit. Most of the route is shown on the 50k map but only the 25k map shows the final road from NH672750 which goes to the summit clearing at NH672755. There is a large cairn with extensive views on the right (ENE) near the forest edge but the highest point looks to be just on the left (WSW).
(45 mins (biking), 4.5 miles, 770' of ascent)
