In the UK, we're lucky enough to have a number of stellar walking routes right on our doorsteps.
From the 630-mile South West Coast Path extending through Dorset, Devon, Cornwall and Somerset via the Pennine Way running up the backbone of England to the Scottish National Trail, which terminates at Cape Wrath in the far northern reaches of Scotland, there's no shortage of fantastic walking to be had.
However, if you ever fancy a change of scenery and weather, you might want to consider catching a flight and taking on one of the following world-class trails:
Milford Track, South Island, New Zealand
Compared to some of the routes mentioned above, the Milford Track is a relative stroll at just 33.5 miles long. However, what it lacks in distance, it more than makes up for in scenery and is described as 'the finest walk in the world' by the Kiwis. Although they would say so, right?
Allow yourself four days to complete the route through the stunning Fiordland National Park so that you've got plenty of time to soak up the surroundings - ice-carved valleys, mountain rivers, peaceful forests and cascading waterfalls await.
What's great is that you don't need to be Ray Mears or Bear Grylls to complete the Milford Track either, as the trail is maintained to a very high standard and there are comfortable serviced huts dotted along the route.
The journey begins in Glade Wharf at the head of Lake Te Anau and ends at Sandfly Point in the breathtaking Milford Sound - an unimaginably picturesque fjord, surrounded by tree-lined peaks. Perhaps the locals are right, after all?
Pacific Crest Trail, USA
At the opposite end of the hiking scale to the Milford Track, the Pacific Crest Trail is an epic 2,650-mile wilderness route stretching all the way from Mexico to Canada via California, Oregon, and Washington.
Along the way, you'll walk through deserts, mountains and forests in some of the most remote and spectacular landscapes on the American continent.
The PCT, as it is informally known, forms one part of the revered 'Triple Crown of Hiking', along with the near 2,200-mile Appalachian Trail and the more than 3,000-mile Continental Divide Trail. In order to complete all three, you must cover almost 8,000 miles (equal to the distance from Zagreb to Hawaii) across 22 states and a vertical gain of one million feet, entirely on foot.
As of October 2013, 196 hikers had completed the amazing feat. But in 2001, Brian Robinson achieved the astonishing by becoming the first person to capture the Triple Crown in a calendar year, averaging around 30 miles per day for ten months solid.
Of his record-breaking hike, Karen Berger, author of 'Hiking the Triple Crown', told the Washington Post: "I've quit saying what can and can't be done on the trails. Humans are amazing."
You'd certainly have to go some to emulate Robinson but, rest assured, completing just one of the big three will feel like one hell of an achievement.
Haute Route, France/Switzerland
A little closer to home, the Haute Route is a scenic but demanding trek from Chamonix in France to Zermatt in Switzerland.
The Alpine route passes many of the Alps' tallest peaks and reaches a maximum altitude of 9,800ft, so hikers may encounter snow and ice when trekking early in walking season.
Ten to 12 days are required to complete the 112-mile journey, with stops in mountain huts or valley hotels along the way.
Scenery-wise, there are beautiful contrasts between the rugged snow-capped peaks and lush valleys strewn with colourful flowers, and you'll encounter wildlife such as ibex and chamois along the way. And the final destination, Zermatt, is arguably the most scenic village in the Alps - a car-free chocolate-box resort nestled beneath the iconic Matterhorn. The perfect place to toast your successes.
Inca Trail, Peru
Hardly a secret, the Inca Trail is the most popular trek in South America, with thousands of people completing the short, but action-packed 26-mile 'Classic Route' past the Inca ruins of Llactapata, Runkurakay, Sayacmarca, Phuyupatamarca and Winay Wayna to the incredible lost city of Machu Picchu at almost 8,000ft above sea level.
Hitting altitudes of nearly 14,000ft along the way, you'll need to get fully acclimatised in Cusco before starting the four-day trek to Machu Picchu - arguably the finest end point to any walking trail in the world.
As well as this and the numerous other Inca ruins en route, the trail passes through some stunning mountain scenery, lush cloud-forest and subtropical jungle, making it a real Indiana Jones adventure.
And although it's quite rightly one of the world's most popular hikes, access to the Inca Trail is restricted to ensure it never gets too crowded. Definitely one for the bucket list.
