Large car park at the foot of the Tourmalet, there is a bike park here and there are opportunities to walk to the Néouveille lakes.

Very poorly maintained road (stones, dung, etc.) but without any cars. A good alternative for a quiet climb, definitely to be avoided on the descent.

The road is reserved for bicycles and pedestrians, it's really pleasant, especially with everything else being full of cars... it's a nice break, plus the view is magnificent, we really appreciate it!

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!

Ascent to the summit on foot; no cable car access until 2027. No access to the restaurant or restrooms, but drinking water is available.

Octave Lapize, the first to climb it on a bike during the tour. Check out the history, it's unmissable.

However, larger towns like Barèges, which serves as a starting point for routes like the Col du Tourmalet – Tourmalet Pass loop, often have bus services. It's advisable to check local public transport schedules for specific routes and connections to trail starting points.
In areas like Barèges, which is a common starting point for several routes, you will find cafes and restaurants. Along the trails themselves, especially in more remote alpine sections, amenities might be scarce.

Given the alpine environment, it's essential to be well-prepared. Always bring a helmet, appropriate cycling gear, plenty of water, snacks, a repair kit, and a first-aid kit. Weather in the mountains can change rapidly, so layered clothing, including waterproofs, is highly recommended. A fully charged phone and a navigation device (like komoot) are also crucial.
