The end of the summer season, when the crowds have left but the sun’s still showing and the light is fantastic- is the perfect time for a walking holiday exploring a selection of Britain’s most spectacular landscapes.

Walking holiday specialist Celtic Trails has shared its top three trips to book now for late summer, each offering active days exploring stunning scenery on foot and breathing in fresh sea or mountain air, coupled with exciting sightseeing and experiences. However these three spots are the lesser known walking areas so away from the crowds.

Priced from just £495 per person, the holidays suit a variety of walking abilities and come with the Celtic Trails expert, easy-to-follow, route plans and pre-arranged luggage transfers. Full details are available to view and book at the website.

The Isle of Arran Coast, 64.5 Miles over Five Days, Moderate

Due to its position in the Gulf Stream, the peaceful Isle of Arran is more temperate than the rest of Scotland, where palm trees are common sights, making a late summer walking trip most enjoyable. This route takes you past rugged mountains and green hills, farmland and wild forests, streams and waterfalls, rugged shorelines, cliffs and beaches, charming villages and fascinating ancient sites.

The walk starts and ends in Brodick, home of Brodick Castle, Britain’s only island country park with magnificent gardens to explore. Other highlights include the Bronze Age Machrie Stone Circle and the whisky distillery at Lochranza for a welcome wee dram after a long walk. The itinerary also has an optional rest day, during which you can explore the local area at your leisure. The itinerary is all fully flexible with a choice of daily distances to suit requirements.

Glyndŵr’s Way in Mid Wales, 132 Miles over Five Days, Moderate to Challenging

Named after the heroic Welsh Prince Owain Glyndŵr, this walk will take you right into the remote heart of Wales, where Glyndŵr planned his own legendary revolt. As Wales’ most recent National Trail, it is also full of impressive sites including Cadair Idris, one of the country’s most dramatic mountain peaks, the Lake Vyrnwy reservoir, Powys Castle and the estuary town of Machynlleth.

Beginning in Knighton, the route follows a horseshoe trail through the valleys of the Radnorshire Hills, walking through ancient woodland, remote farms and isolated Welsh hamlets. Stop to view Lake Vyrnwy’s mystical setting before descending towards the beautiful Lyn Clywedog reservoir, offering panoramic views of Cardigan Bay in the west and the dramatic peaks of Snowdonia in the north. Pass through the pretty town of Machynlleth and finally finish in Welshpool. Here, the route joins with the iconic Offa’s Dyke where, if you wish, you could return along the trail to your starting point.

Guernsey Coastal Path, 38 Miles over Four Days- Easy

Guernsey enjoy average summer temperatures of 22 degrees C stretching well into late August and September, making it a lovely time to visit. As a bonus the island is less busy than the likes of Jersey and the Isle of Wight, and the cliff walking is wilder, too.

The Guernsey Coastal Path walk starts and ends in St Peter Port, the island’s capital. The full route covers between 8-12 miles per day, encompassing tiny Petit Bot Bay cut into ochre cliffs as well as the picturesque working fishing bay of Portelet Harbour and the gloriously unspoilt Cobo Bay. One highlight is Renoir’s Viewpoint, where the famous French Impressionist artist created 15 paintings of the island’s magnificent cliffs and bays during his stay in 1883. An optional rest day spent exploring the quiet neighboring islands of Sark and Herm is available.
