Yes, sightseeing passes in Chamonix can include access to local buses, but it depends on the type of pass you purchase.

If you have a Mont Blanc Unlimited (MBU) pass — even if used only for sightseeing — it includes free access to the Chamonix valley public transport system, including:

• Chamonix Bus network (including routes to Les Houches, Argentière, and Vallorcine)
• Mont Blanc Express train (between Servoz and Vallorcine)

However, if you buy a single sightseeing ticket (e.g., just for the Aiguille du Midi or Montenvers), bus access is not included unless you separately qualify for free travel (e.g., with a guest card from your accommodation).

For full sightseeing access with transport benefits, we recommend the MBU pass, even for non-skiers.
