A deeply wooded red-sandstone gorge where the Clare River marks the Limerick–Tipperary border, cascading through a series of waterfalls, rapids, and natural rock pools. Two looped trails make it an easy, family-friendly escape into a Tolkien-esque landscape.
Two waymarked loops start at the metal swing gate beside Clare River Bridge. The 2 km Nature Loop (30–60 min, green arrows) is the gentler option, while the 4 km Glen Loop (1–1.5 hrs, purple arrows) follows upper woodland paths to Clare Falls before returning on the opposite bank. Both cross footbridges that switch you between counties Limerick and Tipperary. Rated easy to moderate — firm track on the Limerick side, but sections can be muddy and slightly scrambly.
The Clare River tumbles over red sandstone in a series of cascades — most are 3–10 m tall, more cascade than sheer drop. You'll hear them before you see them. The riverside path offers glimpses through dense holly, hazel and pine, with steep side-paths leading down to plunge pools for closer views.
The largest and only officially named fall on the river, The Big Eas sits near the farthest point of the Glen Loop. A wooden footbridge here gives the best vantage point — cross it to pass from Tipperary into Limerick. The opening below the falls is a popular photo spot.
Natural rock pools and deeper swimming spots are dotted along the river. On warm days, you'll see people taking a dip in the crystal-clear water. Approach with care — rocks can be slippery and water depth varies.
The Clare River through the glens is a Grade 3–4 kayaking run — a serious challenge for experienced paddlers only. Put-in is at the top car park near Ashroe, with a 2 km descent over waterfalls and rapids.
Keep an eye out for red squirrels, wrens, wagtails and chaffinches among the oak, pine, holly and hazel. The glen is a designated Special Area of Conservation, home to the extremely rare Killarney Fern.
