What is more beautiful than cycling in the high Alps? Cycling in the Alps up to an alpine lake!
Most of the largest high altitude lakes are created by man-made dams – usually built to supply hydro-electric power. Many of the highest dams in the world are situated here.
From a cyclist’s point of view, there are three great thing about Alpine dams:
- Dams are often very high, accumulating water from Glacier melt
- Dams need quality access roads for the service personnel
- These roads are often “dead-ends” and thus have virtually no traffic
10 15 great cycling climbs up to alpine dams / lakes (map at bottom).
#1. Lac d’Emosson
Steep climbing to a stunning location. The first dam at Emosson was built in the 1920′s to supply electricity to the Swiss National Railway.
Note, the 3rd photo above: there is a slightly insane road that is ride-able above the dam up to a smaller dam / lake above. Details here.
#2. Lac de Roselend
Above Beaufort, the route over Cormet de Roselend appears frequently in the Tour de France.
While there is a direct way up via Col du Meraillet, the better route is via the super steep Col du Pré. This allows superb views from above the Lake – as well as letting you ride over the dam itself on the way to Roselend. Remember the lake is several kilometres below the summit.
Details here. Note, the route in this link also includes a detour to another beautiful Alpine Lake/Dam: Lac de Saint Guérin.
#3. La Grande Dixence
The biggest of the many alpine dams in the Valais region of Switzerland.
This gigantic dam collects water from 35 glaciers. At 285 metres it is currently the 3rd highest dam in the world – a third higher than the Hoover Dam. It weighs more than the great Pyramid of Cheops. Details here.
#4. Lac de Sanetsch
The huge climb over Col du Sanetsch to the lake was one of the most pleasant surprises last year. A beautiful, quiet road.
There is only a road on the south side. But at the dam is a little cable car that will take bikes up/down the north side from near Gsteig. Eric once carried his bike up the trails here. Only recommended for the slightly crazy. Details here.
There are several dams near the top of Grimsel Pass. From the north, this climb is huge. From the south, the hairpins are unbelievable. Details here.
#6. Lac de Mauvoisin
Another steep, beautiful, deserted road up to the 13th highest dam in the world. The start point is the same start point for Verbier and near the start for Col du Grand St. Bernard.
See the video in the link: It’s necessary to brave a little tunnel to get up on top of the dam. Details here.
#7. Lac de Saint Guérin
With the same start point as Roselend, this great route leads to a smaller, but very pretty dam / lake.
Stop for a drink to enjoy the view, but don’t stop, as this lake is only part way up the fantastic climb to Cormet d’Arèches. Details here.
#8. Lac de Mont Cenis
I’ve only cycled the French side, but the Italian side is apparently much more interesting.
The climb starts from the same spot as the magnificent south side of Col de l’Iseran.
#9. Lac de Grand Maison
This large French lake is near the top of the legendary north side of Col de la Croix de Fer (and Glandon).
It’s at the point where the roads finally gets a little less steep – so while participating in La Marmotte you can enjoy the views. Details here.
Oberalppass is not the hardest climb in the cycling Mecca region around Andermatt, but it is still over 2,000 metres and is certainly idyllic.
It features in the June 2010 Tour de Suisse and even has a train station at the top for the famed Glacier Express. Details here.
Note: I am going to keep addind to this list as I find more great climbs. Here’s two that are as tough as any on this list:
#11 Mattmark See
The route starts in Visp in the main valley. The first nine kilometres is the same road that leads to Zermatt and the Matterhorn, so there is some traffic. But once the route turns towards Saas Fee things get quieter.
It’s not the hardest climb but 1580 metres of ascent is, for example, much bigger more than any climb in this year’s Tour. More details here.
#12 Lac de Moiry
The ascent to Lac de Moiry has to be one of the hardest of these alpine lake climbs. 2100 metres (7000 feet), hard work.
I took the harder but quieter route via Vercorin – it adds 300 metres of climbing but has far less traffic. See the map for the easier route, which I used for the descent. More details here.
#13 Lac de l’Hongrin
Beautiful vineyards, a challenging climb, a long tunnel, military checkpoints, an alpine dam/lake, and a beautiful castle – this loop has it all.
And most of it is virtually deserted! Details here.
#14 Route des Lacs
This is my favourite route in the Pyrenées. This lessor know route in fact passes 5 Alpine lakes including the fabulous climb to Lac de Cap de Long. Truly amazing.
#15 Lac des Gloriettes
High in the Pyrenées above Gavarnie is a fabulous, deserted ride to Cirque de Troumouse. On the way down I made a small detour up to the dam at Lac des Gloriettes. Details here.
A FINAL WORD:
This list is by no means even remotely comprehensive. Feel free to suggest your favourite alpine lake /dam.
