Its quite a huge area with lots of cute little villages dotting the lakes and in summer is at peak beauty. One can access it from the south or as I did from the North arriving at Penrith by train from London and taking the bus from Penrith to Keswick. I based myself at Keswick at a hostel. There are at least 2 hostels and that makes staying in the Lake district for a longer period of time affordable. In summer lots of buses link most of the villages. Buy a day pass and hop an and hop off any or all the buses. The days are so long and you can do many things. There are all sorts of walking trails like this one that goes round the lake in Buttermere. Its no wonder many writers and poets called the Lake district home like Beatrix Potter, William Wordsworth and John Ruskin just to name a few. It really is a must see.
