Where is the high street?
High Street is south of Ullswater and runs all the way to Windermere.
Totally different route to Helvellyn.
When I did Helvellyn on the MTB I started from Glenridding, headed east along the lakeside, turned left up the A5091 to Dockray, left again to High Row, picked up the bridleway at Groovebeck Fold, then over Matterdale Common, the Dodd’s (Great, Watsons’s & Stybarrow), Raise, Whiteside Bank, and onto Helvellyn Summit.
To descend, I backtracked down Whiteseide Bank and took the bridleway down Red Screes/Keppel Cove/Glenridding Common, and back down into the centre of Glenridding.
All in blazing sunshine with stunning views across the Lakes.
I would recomment waiting for good weather if poss.
