Countryside Walks

A Whitsbury

This short 6 km walk starts in the village of Whitsbury and goes through both farmland and woodland. The path is well signposted and completely on level ground. The 16th-century Braemore House is at the end of the walk and is open to the public. There is also a museum and cafe here.

B Gullane Bay

This 14 km walk begins at the Aberlady Nature Reserve, where there are 55 different types of birds, and then follows the coast to North Berwick. Although quite long, this is an easy walk on flat ground, most of it being across the sandy beach of Gullane Bay.

C Kingston

This 6 km walk only takes 2 hours, is well signposted and is completely on flat ground. It begins in the village of Kingston and then heads south to the coast. The ruins of 12th-century Corfe Castle are on route and are a popular place for a picnic lunch.

D Radnor

Although this long 14 km walk is mostly on paths, at certain points the route is not marked and directions require care. The walk starts in Radnor Forest and then continues steeply uphill. It's a hard climb up Fron Hill but it is peaceful at the top and walkers can see all the way to the Black Mountains.

E St Agnes

The starting point for this short 7 km walk is the village of St Agnes. The walk then continues along the side of a valley until it reaches the coast. The climb up the cliffs is not difficult and from the top walkers can see for miles around. The area is well known for seabirds with over 900 pairs of kittiwakes nesting here.

F Croft Ambrey

Although fairly short, this 7 km walk offers surprising variety. It is mainly in woodland but also passes by Fishpool Valley and the 14th-century Croft Castle. The path is well signposted and on flat ground, making it a suitable walk for all age groups.

G Langdale

This challenging 15 km walk is mostly on high ground and at certain points there are some steep climbs. A map is important as the route is not always signposted. There is a restaurant at the end of the walk in the small village of Elterwater.

H Alnwick

Although long, this 14 km circular walk is always very popular. It is a well-signposted path that begins and finishes at Alnwick, where there is an 11th-century castle and a range of restaurants. The path takes you through parkland and alongside the River Aln. It then heads west and begins a gentle climb up to Brizlee.
