A longer undertaking is the complete north-east to south-west boggy ridge that runs from the Sally Gap to Carrigvore , and then on to Gravale , and then after a col, the ridge continues south-westwards to meet Duff Hill , and then on to Mullaghcleevaun East Top and Mullaghcleevaun itself. Getting from the Sally Gap to Mullaghcleevan is itself an 8.5-kilometre 3-4 hour walk, which some hill walkers avoid having to completely retrace back to the Sally Gap, and thus completing a 7-hour walk, by instead using two cars.
