Lake Windermere was created 13,000 years ago. This ribbon lake is ten and a half miles long and 219 feet deep, making it the largest natural lake in England.
You can explore the lakeside on foot, but at 45 miles you might want to break it into stages. Alternatively, hire a boat and sail or row around it, visiting some of the 18 islands along the way.
To the west of the lake is Grizedale Forest Park. Here, you'll find mountain bike trails for all abilities and perhaps evidence of Houndtrailing, one of Cumbria's oldest sports.
Beatrix Potter's cosy 17th century cottage, Hill Top, is also in the area. It's now run by the National Trust and is largely untouched. For something a little more up-to-date, visit the World of Beatrix Potter Attraction in Crag Brow.
Clad in grey Lancaster stone, this city's architecture stands out from the verdant landscape of the Lake District.
A gothic Cathedral city, it was once home to the medieval House of Lancaster, major players in the Wars of the Roses.
First stop should be the castle. Once the seat of John O'Gaunt, it was a working prison until 2011. The keep dates from the 12th century and it became famous for a series of witch trials in the 17th century.
Markets also play a major part in Lancaster life, with Charter Market and The Assembly Rooms Market selling crafts and artisan foods.
If you fancy a drive, head up to the Trough of Bowland viewpoint. Or, if you want some seaside glitz, Blackpool is only a short road trip away.
Once described as "a place almost too beautiful to live in", the market town of Keswick is one of the most romantic parts of the Lake District.
West of the town is Derwentwater, where you can climb Catbells fell for some impressive photos.
Or on the opposite side is Friar's Crag, which has the best views across the lake as well as the 5,000 year old Castlerigg stone circle.
The lakeside walk is only an eight mile round trip, but you'll get the best view by cruising, sailing or paddling around Derwentwater itself.
Alternatively, the Keswick Adventure Centre can take you Ghyll scrambling - basically caving with the roof off - as you negotiate streams and gorges on foot.
The area also has a history of Copper and Graphite mining, the humble pencil was invented here (and yes, there's even a Pencil Museum).
