Walking to Alcock Tarn from Grasmere village is a popular walk with many visitors to this part of the Lake District.
From the tarn, the views open across Grasmere Lake and the surrounding fells.
You can choose the straightforward path to the tarn itself or extend the day along ridges and circular loops that take in additional summits.
This guide presents four carefully hand-picked routes, each with clear descriptions, accurate statistics and practical information to support good planning.
Alcock Tarn Walk from Grasmere Village
The route starts near the centre of Grasmere village and follows a clear path that rises through woodland before reaching open fellside.
Steep sections appear in places with zig-zag turns to ease the gradient.
The path leads directly to Alcock Tarn, a small body of water set on the hillside.
From the edge of the tarn, you gain wide views across Grasmere Lake, the village below and the distinctive shape of Helm Crag opposite.
The return follows the outward route downhill.
The gradual reveal of the landscape as height is gained adds to the enjoyment.
- Length: 6 km (3.7 miles) round trip
- Estimated time: 2 to 3 hours
- Difficulty: Moderate
Heron Pike and Alcock Tarn Walk from Grasmere
This longer outing follows the same initial path to Alcock Tarn, then continues uphill along the ridge to the summit of Heron Pike.
The terrain changes from woodland and grassy slopes to a more exposed ridge with some rocky ground underfoot.
At the top of Heron Pike, the views extend across a wide sweep of central Lake District fells.
The descent retraces the ridge and returns via the tarn.
Walkers who complete this route enjoy an extra summit and broader panoramas while still starting and finishing close to the village of Grasmere.
The added distance and elevation create a satisfying sense of achievement without requiring a full day on the hills.
- Length: 8 km (5 miles) round trip
- Estimated time: 3 to 4 hours
- Difficulty: Moderate
Stone Arthur, Alcock Tarn and Nab Scar Circular Walk
This circular route combines several distinct fells into a single loop that begins and ends in Grasmere.
The path first climbs to the rocky top of Stone Arthur, then follows the ridge line past Heron Pike before dropping toward Alcock Tarn.
From there it continues to Nab Scar with its fine outlook over Rydal Water.
The final section returns through lower ground and woodland back to the village.
Terrain varies between clear paths, steeper rocky stretches and occasional boggy patches near the tarn after rain.
The ridge-walking section offers a sense of exposure and achievement as several summits are visited in sequence.
- Length: 9.5 km (5.9 miles)
- Estimated time: 4 to 5 hours
- Difficulty: Moderate to Hard
Alcock Tarn, Rydal and Grasmere Circular Walk
The route climbs from Grasmere village to Alcock Tarn on the initial steep path, then swings across the hillside toward the Rydal area.
It passes Nab Scar and descends toward Rydal Water before completing the loop back through Grasmere.
You will pass a mix of open fell, woodland edges and lakeside sections.
The circular nature means constant changes in outlook, from high valley views at the tarn to the gentler scenery around the two lakes.
This option works well when walkers prefer a loop rather than an out-and-back route while still visiting the tarn.
The varied terrain keeps interest high throughout the day.
- Length: 8 km (5 miles)
- Estimated time: 3 to 4 hours
- Difficulty: Moderate

About Alcock Tarn
Alcock Tarn occupies a sheltered position on the slopes above Grasmere village at an elevation of approximately 300 metres.
This modest body of water was enlarged by a dam during the Victorian era to serve local water needs.
The surrounding terrain includes a mix of grass and heather, with the path offering increasingly open vistas as elevation increases.
Many walkers use the tarn as a turning point or a rest point before deciding to extend their route along the ridge or return directly.
Its location also makes it a natural starting point for ascents toward Heron Pike and beyond.
Tips for Walking in the Area
Good preparation makes all the difference when walking from Grasmere village to Alcock Tarn and beyond.
Begin by checking the latest weather forecast from a reliable source.
Conditions on the fells can change rapidly, with rain, wind or low cloud appearing even when the valley looks settled.
Sturdy walking boots with ankle support and good grip are essential for the steep sections and occasional rocky or slippery ground.
Carry a waterproof jacket and trousers, plus extra layers, so clothing can be adjusted as temperatures and exertion levels vary.
Navigation tools matter on the longer ridge routes. An Ordnance Survey map combined with a compass provides reliable backup, while a fully charged phone with a downloaded offline map offers additional reassurance.
Tell a responsible person the planned route and expected return time before setting out.
Take enough water and energy-rich snacks, especially on warmer days or when tackling longer routes with more elevation gain.
Respect for the landscape helps preserve the area for future visitors.
Stick to established paths to reduce erosion and avoid disturbing ground-nesting birds during spring and early summer.
Take all litter home, and consider carrying a small bag to collect any waste you find along the way.
In wetter months, some sections near the tarn can become boggy, so gaiters or waterproof trousers prove useful.
Dogs are welcome on most paths but should remain under close control, particularly near livestock.
Spring and autumn often deliver the best balance of long daylight hours and fewer crowds, while summer brings vibrant wildflowers on the lower slopes.
Winter walks require extra caution due to possible ice on higher ground and shorter days.
