But here's the problem: 99% of trail articles throw 15 routes at you without telling you which one to run tomorrow morning. This guide is different. We live here, we trail here year-round, and we're going to show you exactly which 5 official routes are actually worth it, how to handle July heat, where to avoid Abondance cows, and how to plan your perfect trail weekend.

🏔️ Why Morzine = Perfect Trail Base Camp
Most trail stations are either too low (Annecy = 450m) or too high (Chamonix = accommodation at 1000m+ = expensive + complicated access). Morzine is right in the sweet spot: town center at 1000m, summits at 2400m.
Translation: you sleep comfortably (no altitude sickness), eat at real restaurants at night, AND you hit alpine elevation gains during the day. The perfect combo.
"We've tested lots of trail bases in the Alps. Morzine beats them all on one simple criterion: you only need your car to GET here. Once you're here, you lace up at the chalet and you're off. Zero parking logistics in the morning."
From Morzine center:
- 🚶 Lake Montriond start: 15 min bike
- 🚶 Morzinette start: 5 min walk
- 🚗 Verticale Nantaux start: 5 min car (or 15 min warm-up jog)
- 🚶 Super Morzine Ridges start: Direct gondola
- 🚗 Col de Cou start: 10 min car
= No time constraints, no mandatory shuttle, no tight timing. You wake up, you run, you come back. Simple.

⭐ The 5 Official Routes You Need to Know
Morzine has 30+ marked trail routes. Here are the 5 we actually run, ranked by what they bring you.
#1 Lake Montriond (Route 7 Blue)
Description
The Lake Montriond loop is 14km of forest trail along the Dranse River then around a turquoise alpine lake. Flowing terrain (90% wide path), perfect for long runs where you just want to run without stumbling. The elevation gain is spread out (no big wall), so it's accessible even if you're not used to mountain running.
The lake itself is beautiful (clear waters, forest all around), and there's a waterfall at the end (Cascade d'Ardent) you can check out in 10 extra minutes. In summer, lots of families swimming = chill vibe.
Why It's in the Top 5
- Perfect day 1 (altitude acclimatization without burning out)
- Flowing terrain (ideal for tempo or speed work)
- Swimming possible (cold water but feels good!)
- Family accessible (kids 8+ can follow walking)
"This is the trail we recommend to all our guests on day 1. Why? Because it's easy enough not to burn you out, pretty enough to make you want to continue, and it shows you if you're handling altitude or not. If you feel heavy here, it's normal. Tomorrow will be better."
- Lake Montriond parking (free, but full after 10am in summer)
- Alternative: bike from Morzine (15 min flat road)
- Very crowded with walkers in August (leave early)
#2 Morzinette (Route 5 Blue)
Description
Morzinette is our "routine" run. Progressive climb through forest (15-20% steady), arrival at Morzinette alpine chalets with Avoriaz views, then technical but pleasant descent. The distance/elevation ratio is perfect for a 1h30 morning session.
The trail alternates dense forest and open passages. The initial climb is sustained but without technical surprises, so you can hit a steady rhythm without watching your feet. At the top, beautiful view of the valley and the Dents du Midi on the Swiss side.
Why It's in the Top 5
- Perfect balance (11 km, 780m gain = ideal training format)
- Center proximity (start 5 min walk)
- Perfect training (steady climb for threshold work)
- Alpine charm (authentic Savoyard chalets)
"This is our weekly trail. We do it at least once a week year-round. It's the right format to maintain fitness: not too long, enough gain to feel the quads, and back in 1h30 flat. All local trail runners know this trail by heart."
🏃♂️ Strava: "Morzinette Climb" segment very popular with locals. It's the regular test to see if your fitness is improving. Good runners finish under 40 min watch time.
- Initial climb sustained in forest (progressive warm-up recommended)
- Technical descent in places (watch your knees)
- South exposure = hot in summer afternoon (do it before 10am)
#3 Verticale de Nantaux (Route 21 Red)
Description
The Verticale de Nantaux is THE legendary vertical kilometer of the area. 1003 meters of positive elevation gain in 2.66 km. Translation: average gradient 37%, with passages up to 40%. It's short, it's brutal, it's the ultimate mountain VO2 max test.
Start at Montriond (5 min car from Morzine), climb-only without descent (you descend the same way or variant). Trail alternates dense forest and open alpine pastures. Breathtaking view once at the top of Lake Montriond and the valley.
Why It's in the Top 5
- Pure challenge (legendary mountain VO2 max test)
- Short but intense (ideal for cardio session < 2h round trip)
- Cult Strava segment (all local pros tackle it)
- Panoramic view (reward at summit)
"If you want to know where you stand on mountain VO2 max, do the Nantaux VK. It's the benchmark test around here. Local record: 33 minutes (Alexis Sevennec). To position yourself: -50 min = very good, -1h = good, -1h15 = decent for beginners. And trust me, you're going to suffer!"
🏃♂️ Strava: The "VK Nantaux" segment is THE leaderboard to check. This is where trail runners in the region come to test their early season form. Very active on Strava with hundreds of attempts each summer.
- Hellish gradient (up to 40%) - poles recommended
- Technical descent that kills knees (take your time)
- Start Montriond (5 min car OR 15 min warm-up jog from Morzine)
- NOT for beginners - advanced level required
#4 Super Morzine Ridges (Route 13 Blue)
Description
The Super Morzine Ridges is the "360° panorama view" trail. You take the Super Morzine gondola then the Zore chairlift, and you run on the ridges in alpine meadows. Near-flat (just 299m gain over 15 km), playful "up & down" profile, and super open view over neighboring valleys.
The terrain is a mix of alpine singletrack and wide paths. You run at altitude (1800-2000m) without doing mountaineering. Views of the Dents du Midi, Avoriaz, and on clear days all the way to Mont Blanc. Gentle descent to Avoriaz or back to Super Morzine.
Why It's in the Top 5
- Exceptional panorama (360° view over Alps)
- Flowing profile (perfect for running fast at altitude)
- Easy altitude gain (gondola + chairlift = 1800m effortlessly)
- Uncrowded (local secret, tourists don't come here)
"This is our 'when we want peace and quiet' trail. Zero crowds even in mid-August, and the panorama is insane. The cool thing: you take the lifts to gain 600m, and then you run at altitude on near-flat terrain. Perfect for days when you don't want to suffer but still want crazy scenery."
🏃♂️ Strava: "Super Morzine Ridges" segment less well-known than others but highly appreciated by trail runners looking for tranquility. Good alternative when Morzinette and Nantaux are crowded.
- Gondola + chairlift required (cost ~€12)
- Lift hours: 8:30am-5pm (last descent 5:30pm)
- Full south exposure = hot afternoon (or do it after 3pm when it cools down)
- Many cows in pasture (stay on trail)
#5 Col de Cou - Fornet (Route 4 Black)
Description
Col de Cou - Fornet is Morzine's wild ultra. 31.5 km and almost 1900m of positive elevation gain through the Manche valley, passing by Col de Cou (Swiss border), Vanet ridge, Col du Fornet, Mines d'Or Lake, and return via Hauts Forts. Total immersion in nature, you don't see anyone on certain sections.
This is THE ultra preparation route par excellence. Varied terrain (forest, pastures, ridges, scree), total isolation, and maximum muscular commitment. Reserved for experienced trail runners preparing a big objective. Complete self-sufficiency for water/food required.
Why It's in the Top 5
- Absolutely wild (Manche valley = zero infrastructure)
- Franco-Swiss border (international ridges)
- Ultra volume (perfect prep UTMB, CCC, etc.)
- Wildlife encounters (chamois, ibex, golden eagles)
"This is our 'big monthly run'. We do it when we're preparing an ultra or really want to test ourselves. The Manche valley is incredibly beautiful, but it's also total isolation. No emergency exit, no resupply, no mobile network in places. You need to be self-sufficient and know what you're getting into. But the adventure feeling is unique."
🏃♂️ Strava: "Col de Cou - Fornet" segment is a classic for trail runners preparing UTMB or TDS. Very technical, very long, but ultra-rewarding. Local record around 3h45 (pros), 4h30-5h for good amateurs.
- Muscularly demanding (almost 1900m gain over 31 km)
- Total isolation on certain sections (bring water + gels + charged phone)
- No mobile network in Manche valley
- Unpredictable weather (storms possible after 2pm)
- Early start mandatory (7am max to finish before storms)
- Experts only - NOT for beginners

🔧 Local Logistics (What Nobody Tells You)
Heat Management & Optimal Timing
"Morzine in July-August isn't 'mountain freshness'. Town center hits 28-32°C in the afternoon. And south-facing trails (Morzinette, Nantaux) become ovens."
Strategy by route:
| Route | Exposure | Best Time |
|---|---|---|
| Morzinette | South | Before 9am (oven after) |
| Verticale Nantaux | South-East | 7am-10am max |
| Lake Montriond | Forest + North | All day OK |
| Super Morzine Ridges | Open altitude | Afternoon OK (wind cools) |
| Col de Cou | North valley | Start 7am (storms 3pm) |
Reliable Water Points
Tested fountains (drinkable):
- ✅ Morzine center (fountain Place Baraty)
- ✅ Lake Montriond parking
- ✅ Montriond village (Nantaux start)
- ✅ Super Morzine (gondola base)
Natural sources (treat or risk):
- ⚠️ Mountain streams: possible parasites (Giardia)
- ⚠️ If absolutely needed: LifeStraw filter recommended
"Always leave with 1L minimum. In 25°C+, count 1.5L for 15 km. For Col de Cou (31 km), take 2L minimum. We've seen too many people in trouble."
Mistakes to Avoid
❌ MISTAKE #1: Leaving after 10am in July
"You're going to cook. South trails (Morzinette, Nantaux) are in full sun 11am-5pm. Start 7-8am max."
❌ MISTAKE #2: Ignoring Abondance cows
"They're everywhere in pasture (May-September). They're friendly BUT: never pass between a mother and her calf. Go around, even if it takes 5 min. They charge if they feel threatened."
❌ MISTAKE #3: Staying on ridges after 2pm in summer
"Storms build fast. If you see gray cumulus, descend. No heroics. Super Morzine Ridges and Col de Cou = lightning risk."
❌ MISTAKE #4: Underestimating the Nantaux VK
"2.66 km sounds short. But 1000m gain in less than 3 km is VIOLENT. If you've never done a VK, take poles and plan 1h15 minimum."
❌ MISTAKE #5: Going solo on Col de Cou without telling anyone
"31 km isolated, no mobile network in places. Tell someone your route + expected return time. Charged phone + power bank mandatory."
