Helvellyn via Thirlmere

Helvellyn via Thirlmere is dog friendly, but with a rating of 6/10 it comes with some important caveats. This is a serious mountain walk covering 11.3 km with 850 metres of ascent, and it's really suited to fit, experienced dogs who are comfortable with sustained effort on rough, exposed terrain. If your dog fits that description, it can be a genuinely rewarding day out together.

There is off-lead time to be had on the broad summit plateau in good conditions, which dogs tend to find a treat after the climb. That said, leads are essential on the lower forest tracks near the reservoir and around the upper crags where other walkers tend to concentrate. It's worth being selective and reading the conditions on the day , wind exposure on the summit can be severe even in summer.

The biggest practical consideration is water , reliable sources become scarce above the treeline, so you'll need to carry everything your dog will drink for the day. The route is a long, committed undertaking with serious wind exposure on the upper fell, so both you and your dog need to be properly prepared. Toilets are available at Swirls Car Park at the start, but there are no facilities on the route itself; the nearest options are in Grasmere or Keswick.
