Trail guide
Cardiac Hill Loop is a 4.5 km (2.8 mile) circuit on Torc’s north side. From the N71 access near the small Cardiac Hill car park, you climb the famous steps, traverse below Torc’s summit, then return through the woods on a gravel path. Allow about 1.5 to 2 hours. The climb is the point: choose this for a short, hard workout with lake views, not as a route to Torc’s summit. If steep stairs or a long stepped descent are a poor fit, save your time for one of Killarney’s gentler lake walks.
The stone staircase rises about 210 metres in roughly 380 metres. Local estimates put it at around 1,250 steps. There are a few short zigzags, but the grade stays steep and the steps keep coming. It feels much tougher than the mileage suggests, and wet stone can be slippery. Take your time and don’t set a pace just because the trail is short.
When the steep climb eases, the path levels along Torc’s northern face. The mountain slope is on one side; gaps in the trees open north across the Lakes of Killarney, the town and the MacGillycuddy’s Reeks on the other. Small lookouts and a shelter give you places to stop without blocking the path. At a lookout, frame a wooded island against the water with the Reeks behind it; that layered view shows how much of the park opens up from the slope. This circuit stays below Torc’s 535-metre summit, so don’t expect the summit route’s final climb or its exact viewpoint.
The route bends down through woodland on another stretch of steps, then reaches a broader gravel and forest path. At the junction, take the gravel descent back toward the N71 starting access to close the loop. The branch toward Torc Waterfall instead reaches the main waterfall car park and adds distance if you need to return to your starting point. It’s a good extension if the waterfall is part of your day, but it isn’t the short loop described here. Some published distances differ because the starting access and that waterfall branch are not always treated the same way.
The route is also called Cardiac Steps or the Red Loop. The nickname is a fair warning about the first climb, and this is the part people remember. The route was laid out a few decades ago; the local nickname has stuck because the climb is so steep. Rhododendron grows along the wooded hillside; cut plants at the trail edge show the ongoing effort to control it.
Use the small N71 car park beyond the main Torc Waterfall lot, cross the busy road carefully, then follow the marked path to the steps sign. The park welcomes dogs, but they must stay on a lead. No trail-specific drinking-water or toilet stop is confirmed along this loop, so bring what you need before leaving the car park.
