The Col du Tourmalet... a pass that was a real challenge for me! It climbs continuously for 20 km without any real respite... With the end getting a bit tougher, especially mentally!

No, Lac de Port Bielh itself is a high-mountain glacial lake primarily accessed by challenging hiking trails. Direct touring cycling to the lake is not feasible due to its high-altitude, unpaved, and difficult terrain. However, the broader Hautes-Pyrénées region and the picturesque Aure Valley, where the lake is located, offer exceptional touring cycling opportunities.
The touring cycling routes in this region are predominantly challenging. Out of approximately 13 routes available, 11 are classified as difficult, and 2 as moderate. This area is known for its demanding ascents over iconic mountain passes and high-altitude environments, making it ideal for experienced cyclists seeking a rigorous ride.
While most routes are difficult, there are a couple of moderate options for touring cyclists. For example, the region offers routes that traverse valleys and foothills, providing a less strenuous experience compared to the high mountain passes. However, there are no routes classified as easy in this specific guide.
Touring cyclists in the Lac de Port Bielh region will experience diverse and stunning landscapes. These include deep valleys, glacial cirques, ancient forests, and areas rich in biodiversity within the Néouvielle National Nature Reserve. You'll encounter granite mountain passes, panoramic views of peaks like Pic du Midi, and numerous high-altitude lakes.
The region features several iconic routes. One popular option is the View of Pic du Midi – Saint Mary of Campan loop from Serpolet, a difficult 39.9 km trail offering expansive views. Another challenging route is the La Mongie – View of Pic du Midi loop from Col du Tourmalet, which includes the renowned Col du Tourmalet.
Yes, many of the touring cycling routes in the Lac de Port Bielh region are designed as loops. Examples include the Tourmalet Pass – Col du Tourmalet loop, which is 12.1 km, and the Tourmalet Pass – Voie Laurent Fignon loop from Skitech, covering 23.4 km. These circular routes allow you to start and finish at the same point, often encompassing significant climbs and descents.
The best time to visit for touring cycling is during the warmer months, typically from late spring to early autumn. This period ensures that high mountain passes are clear of snow and weather conditions are more favorable for challenging rides. The natural splendor of the lakes and mountains is also at its peak during this time.
The area is highly rated by the komoot community, with an average score of 4.7 stars from over 39 reviews. Reviewers often praise the challenging ascents, the breathtaking panoramic views from the mountain passes, and the unique high-mountain environment. The sense of accomplishment after conquering iconic climbs like the Col du Tourmalet is frequently highlighted.
Yes, beyond the specific routes listed, the Hautes-Pyrénées department offers well-established touring cycling routes. For instance, the V81 Pyrenean Piedmont Plain Véloroute (Vélosud) provides a gentler alternative to the high mountain passes, following peaceful roads through hills and valleys with continuous views of the Pyrenees range.
Parking is generally available at common starting points for many routes, especially near popular passes or towns. For example, routes often start from locations like Serpolet or Col du Tourmalet, where parking facilities are typically provided for visitors accessing the mountain areas.
While Lac de Port Bielh itself is a prime spot for swimming after a hike, the broader Néouvielle massif, which you can cycle through or near, is home to around 70 lakes. Many of these glacial lakes offer opportunities for a refreshing dip in their cool waters, especially during the warmer months. Always check local regulations regarding swimming in natural reserves.
The Néouvielle National Nature Reserve, which encompasses much of the area, is known for its rich biodiversity. Cyclists might spot various bird species, marmots, and possibly chamois or ibex in the higher altitudes. The unique subpolar ecosystem also supports diverse flora, particularly ancient pine forests.
