Grasmoor is a colossal fell that dominates the skyline west of Crummock Water. This walk tackles its steep western face head-on, making for a short but brutally steep ascent that will test your legs and lungs. The reward for this effort is a vast, rolling summit plateau and truly exceptional views that span from the Solway Coast to the high peaks of the Scafells and Helvellyn. This is a tough but hugely satisfying route to the top of one of the Lake District's biggest fells.

Step-by-Step Guide
1. Start at Cinderdale Common
Parking is available in a lay-by at Cinderdale Common on the B5289 road that runs alongside Crummock Water (CA13 9UY). From the parking spot, carefully cross the road and take the path that leads away from the lake.
2. Approach via Liza Beck
Follow the path which runs parallel to Liza Beck. You will pass through a gate and begin a gentle ascent towards the imposing face of Grasmoor ahead. The path is clear as it enters the valley between Grasmoor and Whiteside.
3. The Steep Ascent
A path branches off to the right, signposted for Grasmoor. This is where the hard work begins. The path becomes incredibly steep as it climbs relentlessly up the scree and grass of Grasmoor End. Take your time, have frequent breaks, and admire the rapidly expanding views of Crummock Water behind you.
4. To the Summit of Grasmoor
The gradient eventually eases as you reach the vast, flat summit plateau. From here, follow the cairns across the stony ground to the main summit cairn of Grasmoor (852m), which is surprisingly close to the drop back down to the valley.
5. The Descent via Rannerdale
For a more interesting descent, head south from the summit towards Wandope, then bear west to descend to the col of Rannerdale Hause. From here, a path drops down into the beautiful Rannerdale valley, famous for its bluebells in May. Follow the valley path back down to the road near where you started.
Visitor Information & Tips
- A Test of Fitness: Do not underestimate the steepness of the main ascent. It is one of the most direct and punishing climbs in the Lake District.
- Weather Conditions: The summit plateau is very exposed. Avoid this walk in high winds or poor visibility, as navigation can become very difficult.
- Walking Poles Recommended: A pair of walking poles can be a huge help on both the steep ascent and the subsequent descent, taking some of the strain off your knees.
- Rannerdale Bluebells: If you are walking in late April or May, the descent through Rannerdale offers the bonus of seeing one of the Lake District's most spectacular displays of wild bluebells.
