If you don’t feel like a full-on fell walk, the easy path to the clattering waterfall of Sour Milk Ghyll is a great option. The path starts at the end of Easedale Rd and leads for about 1.5 miles along Easedale Beck, the first part is paved and wheel-chair accessible, but it gets rougher the closer you get to the falls.
The ghyll apparently got its name from the milky colour of the water as it foams and rushes down the fellside. You can clamber up the side of the cascade to nearby Easedale Tarn, which Thomas de Quincey considered 'gloomily sublime'. From here, a trail connects to the Easedale Round (see below).
On the way down, you could stop for afternoon tea at Lancrigg; look out for the driveway to the hotel just before you get back to Easedale Rd.
