Location please.

Hello all. I will be travelling to the Lakes tomorrow to tick of Helvellyn ond/or Scafell Pike from my list but the weather isn't looking to be mountain climbing/hiking friendly so I am making a plan B. I love forest walks, rivers and I really love waterfalls. Could anyone suggest waterfalls in the Lake District and I would really appreciate it if you could tell me how to get there and where to park. Thank you in advance.
