Now that spring is in the air, there's a new energy in all of us. The cold is receding and there are acres of stunning Wiltshire countryside to discover.

We love using the National Trust site for some amazing walks and sights in the county, and this is a really interesting one. West Kennet round trail National Trust Museum Barn and takes in history along its length.

Among the archaeological sites and ancient heritage you'll pass are the stones of Avebury Henge and Bronze Age barrows. You'll follow the West Kennet Avenue to the Sanctuary, then climb the hill to West Kennet Long Barrow with panoramic countryside views.

The long barrow is one of Britain's earliest-built structures. It's around 5,650 years old and had already stood for over a thousand years by the time the Great Pyramid in Giza was built.

This is the guided walk from the National Trust. The start point is the Old Farmyard Avebury: Grid reference SU100700W.

1 Starting by the Museum Barn, walk out of the Old Farmyard past the café. Climb the steps into the henge and stone circles, bear left following stones to the road. Take the footpath on your right, then at the end, cross the road and go through the pedestrian gate.

2 Turn left and follow the fence line to the ditch and henge bank. Turn right and continue along the edge of the ditch until you see a pedestrian gate.

3 Go through the gate and onto a lane. Turn left and follow this lane for 700 yards, passing a series of farm buildings on the right.

4 Immediately after the last building, turn right up a track. Walk for about 1 mile until you are almost at the top of the hill.

5 When you get to the Bronze Age barrow with beech trees, go through a pedestrian gate on the right. Follow the path down past another three barrows.

6 At the bottom of the hill you'll see a pedestrian gate. Don't go through, instead turn left along the bottom of the field, following the fence line - until you pass a house - to a gap in the boundary.

7 Go through the gap, cross the road and go over a stile on the opposite side. You are now following West Kennet Avenue. Towards the hedgerow on your left is a fallen standing stone. Turn left and cross the field, going through a gate ahead of you. Cross the minor road, through another gate opposite and into the next field. Continue up the field and through a pedestrian gate to the Sanctuary. Exit through the pedestrian gate opposite the one you came through, turn right and follow the track. After around 250 yards turn right going downhill along the edge of the field.

8 When you reach the road, turn left over a bridge. You will see a track on your right-hand side. Follow this track for around 200 yards and look for a narrow footpath on your right which passes through a line of trees.

9 At the end of the path go over a stile and into a field, keeping the fence line on your left. Cross another stile, over a lane, take the track ahead and go over another stile. After 400 yards turn left and join a path up the hill.

10 Once at the top you have reached West Kennet Long Barrow. To return, head down the hill. At the fence line turn left and follow the path. Go through a kissing gate, cross the river and head for the road. You will see Silbury Hill ahead. Go through a kissing gate, turn left and go through a pedestrian gate on the other side of the road.

11 Keeping the hedge line on your left, continue to follow the path, passing Silbury Hill and the Winterbourne Stream on your left.

12 Follow the stream a further 700 yards until you reach a road, then cross into the National Trust car park. If you wish you can follow the path back to the Old Farmyard for refreshments. You have arrived at National Trust car park, Avebury: Grid reference SU 09960 69654.
