If you're looking to get a spring in your step as the weather warms up, a range of walking guides from Collins will have you expertly traversing the landscape like a Park Ranger.

Each book contains the 20 best routes chosen by National Park rangers; they have easy to follow instructions, maps and tips on what to look out for.

We've picked one walk from the guide to share with you:

Walk 18 - Mill Hill

This non-circular walk takes you from Shoreham-by-sea up by the river valley and around Mill Hill.

Start: Red Lion pub (TQ208056)

Distance: 4 1/2 miles (7.25 km)

Time: 2 1/2 hours (non-circular)

Terrain: mostly flat, grassy bridleways, uneven in places

Nearest Postcode: BN43 5TE

Binoculars are a must for this walk as there is so much wildlife to spot along the route. The chalk grasslands of Mill Hill provide a rich and diverse habitat that attracts over half of the different butterfly species found in Britain and houses 160 species of plant.

Directions:

1) From the bus stop at the Red Lion pub, take St Nicholas Lane until you get to The Street; turn left and head up the hill. Take the footpath signposted to the left and follow it around the field. Continue up to the bridge that crosses the A27. Look out for the great views across the Adur valley.

2) Cross the bridge and at the end take the footpath to the left. Follow this round to Mill Hill Nature Reserve and then take the footpath down the hill. Continue past Old Erringham Farm and back up the road.

3) Turn right and head south along the road until you reach the track on the left-hand side that leads to New Erringham Farm. Follow the road past the farm and round to Mossy Bottom Barn.

4) Leaving the track a short distance east of the barn, turn right and continue down towards Slonk Hill Farm.

5) Cross the bridge over the A27 and continue on the track round to the vehicle entrance to the shopping centre.

6) Carefully cross the road and use the pedestrian route into the car park. The walk ends at the bus stop, located at the south end of the covered walkway.
