How do I get to the Comeragh Mountains from Clonmel?

From Clonmel, take the R678 south through Rathgormack toward Mahon Falls. The Mahon Falls car park is about 30 minutes from Clonmel town centre. For the Nire Valley / Nine Valley side, take the R671 west to Clonmel then south via Ballymacarbry. Always check road conditions — some access roads are narrow and can be muddy after rain.

What is the Kilcommon Loop in the Comeragh Mountains?

The Kilcommon Loop is a 20km circuit in the Comeragh Mountains combining forest tracks with open mountain terrain. It's one of the best documented MTB routes near Clonmel — a solid climb followed by a long descent with views over the Suir Valley. Intermediate to experienced riders. Allow 2-3 hours depending on fitness and conditions.

Are the Comeragh Mountains suitable for beginner mountain bikers?

The lower forestry tracks around the Comeragh base are manageable for confident beginners. The upper mountain terrain — Kilcommon Loop, Coumshingaun rim, Knockanaffrin Ridge — is not suitable for beginners. The terrain is exposed, rocky and remote. Build experience on the lower Faobam trails near Clonmel first before going into the upper Comeraghs.

Comeragh Mountains MTB — Trail Guide from Clonmel

The Comeragh Mountains are 30 minutes south of Clonmel and they're the best mountain biking in the whole area. I've been riding here since I was 11 — the Comeraghs were where I first experienced proper mountain terrain, remote descents, and the kind of views that make you stop the bike just to look. This is my honest guide to what's there and how to ride it.

What makes the Comeraghs special

The Comeraghs are a compact massif on the Tipperary-Waterford border. What makes them unusual in an Irish context is the dramatic glacial topography — deep coums (bowl-shaped valleys carved by glaciers) cut into the mountain sides, creating natural amphitheatres. Coumshingaun is the most famous: a deep lake enclosed by a near-vertical horseshoe of cliff. The mountain terrain on top of the plateau is open, exposed, and seriously rewarding to ride in good conditions.

The mix of Coillte forestry on the lower slopes and open mountain on the upper sections means you can choose your difficulty. The forestry tracks are manageable for most riders; the upper mountain trails require experience and good route-finding.

Kilcommon Loop — the best documented route

The Kilcommon Loop is around 20km. It starts from the Kilcommon area on the Tipperary side of the Comeraghs and combines forest track, open mountain and some gravel road sections into a circuit with a solid climb-and-descent profile. The views over the Suir Valley on the descent section are some of the best you'll get in the south of Ireland.

Allow 2 to 3 hours for the full loop. The climb is sustained — there's no shortcut on the way up — and the descent rewards you properly. This is intermediate-to-experienced territory; the upper sections have loose rock and some exposure. I've done this loop a good few times and it's consistently one of my favourite rides anywhere near Clonmel.

Nine Valley (Nire Valley) — longer days out

The Nire Valley runs west from the main Comeragh massif. The terrain here is different — less dramatic than the upper Comeragh ridges, more rolling, with a mix of valley-floor tracks and lower mountain forest roads. It's excellent for combining with the Kilcommon Loop if you want a bigger day, or as a standalone ride if you want something more mellow. The Nire Valley walk/cycleway gives you a starting point.

Mahon Falls — landmark and trail access

Mahon Falls is the most visited landmark in the Comeraghs. The waterfall itself is impressive, and the car park at Mahon Falls serves as the best access point for a big chunk of the Comeragh riding. From here you can go south to the falls and the forestry above, or north to the mountain plateau. There's no formal MTB trail map from this car park but local knowledge gives you options in every direction.

Coumshingaun rim — expert only

The rim trail above Coumshingaun lake is exposed, technical, and absolutely not for beginners. The path runs along the cliff edge above the lake with serious drop-offs. If you know what you're doing and you're confident in your bike handling, the views are extraordinary. But this is expert-only terrain — one mistake on the rim is serious. I don't ride this one alone.

Knockanaffrin Ridge

The Knockanaffrin ridge runs along the western side of the Comeragh plateau and gives long, exposed ridge riding with views west to Slievenamon and north across Tipperary. The descent lines off the ridge are steep and technical in places. Good summer riding on a dry day — the same terrain in wet conditions is significantly harder and less fun.

Getting there from Clonmel

From Clonmel take the R678 south via Rathgormack to Mahon Falls (about 30 minutes). For the Nire Valley, take the N24 west briefly then south via Ballymacarbry on the R671. Download OS Ireland maps offline before going — mobile signal disappears once you're above the treeline.
