Northern Ireland’s best...
Castle Ward, Strangford Lough
Overlooking the south shores of Strangford Lough, Castle Ward is one of Northern Ireland's finest demesnes or country estates. At its heart lies an unusual Georgian mansion, but there is a lot more to discover here... This walk explores the waterside, a ruined castle, woodland, an ornamental lake and follies. Visit in winter for a chance to see a fantastic range of migrating birds and the resident seals.
The walk is 2.5 miles long, and walked at average speed (about 2mph), could see you burn about 300 calories - you may want to go round the estate twice, or walk more briskly to really make a dent in your Christmas calories!
Rhossili Bay, South Wales
Take in the tremendous coastal views from Rhossili Down before descending to Rhossili Bay, considered one of the finest sandy beaches in the UK. At the southern end of the bay, when the tide is low, a finger of limestone rock leads to Worms Head where seabirds and seals can be seen- a real Christmas treat!
The walk is 5 miles long and will burn about 500 calories when walked at an average pace - although walking barefoot on the sand (if the snow's cleared!) or up a hill or two will burn plenty more.
The best of the North...
Alderley Edge, Cheshire
This beautiful woodland walk begins at Alderley Edge railway station and is just 12 miles south of Manchester. Set around a dramatic sandstone escarpment in rolling Cheshire farmland and mature Scots pines and beech woodlands, the Edge has spectacular views, intriguing legends and an ancient history of copper mining which dates back 4,000 years to the Bronze Age!
The walk is 4.5 miles long so you're likely to burn just under 500 calories; the equivalent of two slices of Christmas cake.
The best of the South...
Staple Plain, Somerset
Wander down through broadleaf woodland, into a bracken filled combe and up to the top of Beacon Hill to savour fantastic panoramic views across the Quantock Hills and beyond. Continue through lowland heathland, listening and looking out for red deer, skylark and Dartford warbler in this wildlife-rich environment.
The walk is 2 miles long so you'll burn about 200 calories. If you want to work harder, take the dog- he or she will encourage you to get moving!
The Midlands’ best...
Calke Park and Abbey, Derby
As well as a grand Baroque mansion with a large natural history collection, Calke has secret walled gardens and 600 acres of parkland, much of which is a National Nature Reserve. The park is a rich and varied landscape of grassland, ponds and wood pasture - one of the rarest habitats in Europe. You'll also find majestic veteran trees and some great 'bug' - watching sites. There are no public roads at Calke so it is perfect for a peaceful walk.
The walk is 1.5 miles long so you’ll probably burn about 200 calories. However, the sights are so pretty that you may well end up strolling round more than once and, given that there are no public roads, you could add to the distance by walking to Calke to start with.
