Or you could walk to
Walla Crag from Keswick town centreSteady gradient. Easy path up to Walla Crag.
Alternatively, catch the boat launch to Ashness Gate landing stage (great lake level view of Walla Crag above) and walk from Ashness Bridge up and over Walla Crag back into Keswick.
I personally think the ascent from Ashness Bridge is quite steep in comparison to the Keswick side but if you managed Latrigg you'll be fine with it. Just take your time. Huffing and puffing is mandatory. Walking up without stopping is not
Go at your own pace. Find your own walking rhythm. Enjoy the views. Consult your map ..... often (justifiable excuse for a breather
).
Don't discount Loughrigg though. As you do more walks and your confidence and experience grows, you'll start to wonder who's been along and flattened the fells so earmark it for a second attempt in the springtime when you've got a few more lake district walks under your belt and built your confidence up a bit
Oh, and those slim folks slipping and sliding down those cobble steps? All that's telling me is that they're going too fast and not taking enough care (maybe wanting to look more experienced and confident than they were?). I go sideways down steps like that and just take my time.
Enjoy. It's a great hobby and the Lakes is a wonderful playground
