Recreation
Hill walking
As the highest mountain in Connacht, Mweelrea is climbed in "Four Peaks Challenge" formats, being the highest mountains in the four provinces of Ireland.
The fastest and most straightforward way to summit Mweelrea is via the 8–kilometre 3-hour ''Silver Strand Route''.
A longer route is the 13-kilometre 6-hour round trip via the Lug More (or ) corrie and the valley of Glen Glencullin that take in the summits of Ben Bury and Ben Lugmore. A notable feature known as ''The Ramp'' is used, which crosses the headwall of this corrie at mid-way, from east to west in an upward slope; reaching the ridge of Ben Lugmore at a col with Ben Bury. While this route is direct, caution is advised in properly finding ''The Ramp'', as the corrie has extensive cliffs.
Mweelrea is also climbed as part of the 15-kilometre 6-7 hour ''Mweelrea Horseshoe'', which is described by a notable Irish guidebook as one of "the top three" in Ireland.
The circuit starts and ends at the ''Delphi Mountain Resort'', and takes in all the peaks of the massif of Mweelrea, including Ben Lugmore (and its subsidiary peaks), Ben Bury, Mweelrea and the Mweelrea SE Spur (or point 495-metres).

), there are long Grade 1 and 2 scrambles on the northeastern slopes of Mweelrea/Ben Bury.
Winter climbing
The Lough Bellawaum corrie, Mweelrea's northeastern corrie, also has a number of winter-climbs, the most notable of which are ''Blue Route'' (Grade II/III, 270 m), and ''Red Route'' (Grade III, 305 m).
