This route was planned by komoot.
The full loop is approximately 55 kilometers. While the komoot tour suggests around 3 hours 45 minutes of pure cycling time, most riders plan for a half to full day to enjoy the scenery, stops, and potential breaks. The overall duration will depend on your fitness level and how often you stop.
This route is generally considered difficult, especially due to the significant climb to the Col du Chat. It requires good to very good fitness for the full loop. However, less strenuous options exist: you can bypass the Col du Chat by using the Tunnel du Chat (reserved for cyclists and pedestrians) or even take a shuttle boat for part of the journey, making it more accessible for those seeking a more relaxed tour.
Aix-les-Bains is a common starting point for the loop, offering various parking options. You can also find parking in other towns around the lake, such as Le Bourget-du-Lac or Chanaz, depending on your preferred starting location.
The route primarily features paved surfaces, including dedicated cycle paths, especially on the eastern side between Aix-les-Bains and Le Bourget-du-Lac. The remainder of the circuit uses shared departmental roads. You'll also cycle along sections of the ViaRhôna and the peaceful banks of the Savières Canal.
The route offers continuous views of Lac du Bourget and the surrounding Jura and Alps mountains. Notable sights include beaches and ports in towns like Le Bourget and Aix-les-Bains, panoramic views from the Climb to Ontex from Conjux and the Viewpoint over Lac du Bourget, charming villages like Chanaz, and the Savoyard vineyards. The majestic Abbaye d'Hautecombe is also visible from various points.
The spring and autumn months typically offer the most pleasant cycling conditions with milder temperatures and fewer crowds. Summer can be popular but also hotter, especially on climbs. Always check the local weather forecast before you go.
Yes, the route incorporates sections of the ViaRhôna and is part of the larger 'Tour du lac du Bourget' official trail. Other trails like 'Tour de la Charvaz' and 'Circuit de la Chambotte' also intersect or run concurrently for portions of the loop.
While the route uses public roads and dedicated cycle paths, specific regulations for dogs can vary by municipality and specific sections (e.g., beaches, nature reserves). It's generally advisable to keep dogs on a leash, especially on shared paths and roads. Always check local signage for any restrictions.
No, there are no specific permits or entrance fees required to cycle the Tour of Lac du Bourget. It is a public route accessible to cyclists.
Cycling clockwise is often recommended to best appreciate the continuous lake views. This direction also positions the main ascent of the Col du Chat in a way that many find enjoyable, though it remains a significant climb regardless of direction.
Yes, the route passes through several towns and villages, including Aix-les-Bains, Le Bourget-du-Lac, and Chanaz, where you can find cafes, restaurants, and shops to refuel and hydrate. There are also various spots to stop for a picnic with lake views.
Very nice but difficult bike tour around the lake, although there was no bike path along the lake on the west side, but large climbs into the mountain range had to be overcome. We were then rewarded with a wonderful view down to the lake and the surrounding towns.
If you look at the komoot map of the tour, you might wonder where the 740 hm come from. But if you look closely, there is a small pass, the Col du Chat, where you have to overcome 400 meters in altitude with a gradient of ∅6.4%. I didn't think the tour would be so nice, as the first part leads directly or along the busy road. However, we are here in the low season and the traffic was limited: At the beginning there were mostly bike lanes, then along the lake (still few tourists there), the well-developed V63 to the "end of the lake" and then over the Col du Chat is a small road with little traffic at the moment, which winds its way up comfortably with wonderful views of the lake over and over again. There are always wonderful vantage points and at the end you will be rewarded with a promising descent. Conclusion: definitely do this tour in the off-season! I would always do the loop in that direction.
Easy even with a bike rented in town in front of the station Very competitive price
Also a very beautiful route with many special places and views. Sometimes quite a climb, also with an E-bike.
At 43km, the road was cut off. We had to turn around and go up to the Granges de Brison, then go down again on a very rocky track. Other than that the track is awesome.
Anti-clockwise tour, free parking departure from the church of Chindrieux
