Not the most scenic. Not the most photographed. The ranking by what the trek actually demands and what it actually delivers: the physical commitment, the technical difficulty, the likelihood that you finish versus the likelihood that you sit in a teahouse on Day 4 wondering whether you made the correct life decision, and the specific natural or cultural encounter that the walk gives and that no road could give you. The Everest Base Camp trail for the Himalayas at eye level. The Camino Frances for the community. The GR20 in Corsica for the instruction in what mountain terrain actually means.

The long-distance trek is the travel experience with the highest ratio of transformation to planning — you walk from one place to another for days or weeks, the body adapts, the mind clears, and the thing you thought you came to see is frequently less significant than what you find along the way. Every serious long-distance walker has this experience eventually: the destination was not the point. The walking was.
This guide covers the six treks most worth doing from the UK traveller’s perspective, ranked by what you are specifically committing to and what you will specifically receive.
The Six Treks
1. The Everest Base Camp Trek, Nepal (12-16 days)
What you’re signing up for: 130km round trip from Lukla to Everest Base Camp at 5,364 metres. 4,000 metres of altitude gain from the starting elevation. The altitude sickness risk is the primary variable — the AMS (Acute Mountain Sickness) affects approximately 25% of trekkers on the standard itinerary, and the protocol (one acclimatisation rest day at Namche Bazaar, another at Dingboche) reduces but does not eliminate the risk. The body responds to altitude as it chooses, not as you plan.
What you actually get: The Khumbu Icefall visible from Base Camp — the moving, creaking, collapsing wall of ice above the camp that the climbing expeditions traverse in the dark to avoid the worst of the daily melt. The Tengboche Monastery at 3,867 metres — the gompa where the monks perform the morning puja as the sun crosses Ama Dablam above. The specific Khumbu quality of the route: the yak trains on the path, the Buddhist prayer flags at every pass, the Sherpa villages that are simultaneously ancient and wired for satellite internet.
The honest physical assessment: Fit adults without mountain experience complete this trek regularly. The fitness required is the sustained walking fitness (6-8 hours of walking per day on uneven terrain) rather than the technical climbing fitness. The altitude is the variable that fitness cannot fully control.
Cost: Nepal trekking permit (NRS 3,000 / £17.40 for the Sagarmatha National Park entry) + the Khumbu Pasang Lhamu Rural Municipality permit (NRS 2,000 / £11.60) + Kathmandu to Lukla flight (USD 150-200 / £118.11-157.48 one way) + accommodation in the teahouses (USD 5-15 / £3.94-11.81 per night) + the guided trek option (USD 30-80 / £23.62-62.99 per day for the private guide and the porter).
When to go: October-November (post-monsoon, the clearest views) or March-May (pre-monsoon, the rhododendron in bloom below 4,000 metres).
2. The Camino Francés (The French Way), Spain (28-33 days)
What you’re signing up for: 778km from Saint-Jean-Pied-de-Port in the French Pyrenees to Santiago de Compostela in Galicia. The most walked long-distance trail in the world — 350,000+ people complete the Camino Francés each year. The community is the defining characteristic: the peregrino culture (the pilgrim network, the hospitalero welcome at the albergue, the peregrina ritual of the stamp in the credential — the pilgrim passport), the people encountered repeatedly over weeks who become the specific community of the walk.
What you actually get: The specific transformation of a month of walking — the first week of physical adaptation (the blisters, the 6am starts, the body complaining), the second week of psychological settlement (the walk becoming the world, the previous life receding), and the third and fourth weeks of the quality that the Camino community calls “the Camino mind” (the specific mental clarity produced by weeks of walking, eating, and sleeping without the technology mediation of ordinary life). This cannot be scheduled. It arrives when it arrives.
The honest assessment: The Camino Francés is the accessible long-distance trek — the infrastructure (the albergues every 5-15km, the blazed trail, the café opening at 6am for the early walker) makes it achievable for anyone in reasonable fitness. It is not technically difficult. It is long. The difficulty is the monotony of the Meseta (the high plateau from Burgos to León — 200km of flat agricultural land, the walk that tests the walker’s relationship with the walk itself).
Cost: The Camino budget (the daily albergue: €12-18 / £10.34-15.52, the pilgrim menu at the bar: €10-15 / £8.62-12.93 for three courses, the transport from the UK to Saint-Jean-Pied-de-Port) — approximately £30-50 / £30-50 per day all-in, £950-1,650 / £950-1,650 for the full 30 days.
3. The GR20, Corsica (14-16 days)
What you’re signing up for: 180km across the Corsican mountain spine from Calenzana in the north to Conca in the south. The GR20 is the hardest long-distance trail in Western Europe by the consensus of the trekking community. The northern section (the first 9 stages) involves sustained scrambling on exposed granite — hands and feet required, the path marked by painted red-white blazes on the boulder faces, the exposure real on several passes. The southern section is walking rather than scrambling.
What you actually get: The Corsican granite landscape — the massif of the island’s central spine, the scree fields, the snow on the high passes until June, the maquis (the aromatic scrubland of the lower slopes — the heather, the myrtle, the juniper, the specific Corsican smell of the mountain vegetation at 1,000 metres). The specific GR20 community: the trail is walked by approximately 10,000 people per year (versus the Camino’s 350,000), the huts (refuges) small, the shared table at the evening meal the community of the day.
The honest assessment: The fitness requirement is significantly above the Camino and the EBC trek. The GR20 requires sustained scrambling confidence, the ability to navigate in poor visibility (the granite can be crossed in the cloud — the blaze-following requires concentration), and the physical endurance for the 8-10 hour stages of the northern section. Complete the southern section first if uncertain about the northern.
Cost: The refuge booking (the CAF and the PNRC huts — €16-25 / £13.79-21.55 per night for the dorm bed, advance booking mandatory from June-September at refugescorse.com) + the half-board (the refuge dinner and breakfast, €30-45 / £25.87-38.79 per night). The Calenzana-Conca transport (Bastia to Calenzana, Conca to Bastia): €30-50 / £25.87-43.10 total.
4. The Annapurna Circuit, Nepal (14-21 days)
What you’re signing up for: 160-230km (the full circuit, the length varying with the route choices) around the Annapurna massif, crossing the Thorong La Pass at 5,416 metres — the highest pass on any major trekking route in the world.
What you actually get: The cultural range — the trail passes through Gurung and Magar villages (the Hindu communities of the lower elevations), the Tibetan Buddhist communities of the upper Mustang (the Manang valley, the Muktinath temple), and the specific Annapurna landscape that includes subtropical gorge, temperate forest, and high-altitude desert in a single route.
The Thorong La at dawn: the cross of the pass (the start at 3am from Thorong Phedi, the 5-hour ascent in the dark, the summit at dawn, the descent into the Mustang) is the definitive Annapurna Circuit experience and one of the most specific mountain moments available on any public trail.
The honest assessment: The Annapurna Circuit is longer, higher, and more varied than the EBC trek. The altitude at the Thorong La exceeds EBC Base Camp by 52 metres. The multi-week commitment (3 weeks is the correct allocation for the full circuit with acclimatisation rest days) is the primary constraint.
Cost: ACAP permit (NRS 3,000 / £17.40) + TIMS card (NRS 2,000 / £11.60) + teahouse accommodation (USD 5-15 / £3.94-11.81/night) + guide and porter (USD 25-70 / £19.69-55.12 per day). Total: £700-1,500 excluding flights.
5. The Tour du Mont Blanc (10-12 days)
What you’re signing up for: 170km circular route around the Mont Blanc massif — the route passes through France, Italy, and Switzerland, crossing 11 mountain passes. The TMB is the most accessible serious alpine trek in Europe — the infrastructure (the refuges, the gîtes d’étape, the cafés at the passes) is the most developed of any mountain circuit on this list.
What you actually get: The Mont Blanc massif from all four sides — the Chamonix valley visible from the Col de Voza on Day 1, the Italian face (the Aiguilles Noires, the Glacier du Miage) from the Val Vény on Day 4, the Swiss valley of Champex on Day 8, and the return to Chamonix through the French valleys on Day 10. The TMB gives the highest-quality alpine landscape per kilometre of any route in this guide.
The honest assessment: The TMB is the physically accessible serious alpine trek — the refuges are within reach, the passes are non-technical (no scrambling or ice work required in the normal summer conditions), and the route is blazed and mappped to the level that skilled navigation is not required. The standard route fitness requirement: the ability to walk 5-8 hours per day on steep terrain with 20-25% gradient sections on several passes.
Cost: Refuge booking (essential from July-September at alternativemontblanc.org and the FFCAM — €35-55 / £30.17-47.41 per night for demi-pension, dinner and breakfast included): total accommodation cost approximately €400-600 / £344.83-517.24. Plus the transport from the UK to Chamonix.
6. The Lycian Way, Turkey (29 days full, 5-7 days section)
What you’re signing up for: 540km along the coast of Lycia (the ancient civilisation of southwestern Turkey) from Fethiye to Antalya, through the Taurus Mountains, past the Lycian rock tombs carved into cliff faces, above the Mediterranean turquoise.
What you particularly get from a 7-day section: The Kas to Antalya section (the eastern end of the trail) gives the best combination of the Lycian archaeological sites (the Patara beach — the widest beach in Turkey, the ancient site visible from the beach, the lighthouse of Patara — the tallest surviving Roman lighthouse) and the coastal mountain terrain. The full trail requires 29 days of accommodation-to-accommodation planning.
Cost: The Lycian Way costs approximately £30-50 / £30-50 per day including the pension accommodation (the family-run pansiyon at the route’s villages, €15-30 / £12.93-25.87 per night with breakfast), the food at the trail villages, and the local transport for the approach and return. The most cost-efficient serious long-distance trek on this list.
