Were Buttermere and Crummock Water once the same lake?

Yes, they were a single long lake until a few thousand years ago. Sail Beck gradually deposited sediment between them, forming an alluvial fan that divided them into two separate bodies of water.

Which is better for a quiet walk, Buttermere or Crummock Water?

Crummock Water is much quieter. Buttermere attracts huge crowds, especially in summer, while Crummock stays relatively peaceful because it doesn't offer an easy circular route that most tourists prefer.

How long does it take to walk around Buttermere?

The circuit is about 7.5 kilometres and takes roughly two to three hours depending on your pace. There's one narrow section along the lakeside with a drop to the water that can be a bit nerve-wracking for some people.
