A common route to the summit of Mullaghcleevaun is from the south via an 8.5-kilometre 3-4 hour walk which starts from a small car-park in the forest below Carraigshouk (the car-park is known locally as The Oasis) just off the R115 road (also called the Old Military Road). This southerly route ascends to Mullaghcleevaun East Top and then to the summit of Mullaghcleevaun, before retracing to the car-park.
