 This  tour is going new on our site but we have actually run it a few times this year  for some private groups; so it is tested.   Our guides just returned last week and they were overwhelmed with the amazing beauty of the region.  Our  guides are French and they were still impressed. The region is one of only a few  places in France that is more or less undisturbed.  Traditions and an old way of  life continue on.  There are many tiny villages but no big cities.  Wildlife  still inhabit the region in their natural environment.  The peaks of the  Pyrenees make you feel like you are on top of the world but are really only  about 8000 ft in elevation.  The dining is informal and hardy in the local  tradition, and the people couldn’t be more sweet and welcoming.  They are proud  of their space and are thrilled to have travelers come to see  it.    We  are presenting this trip to clients as if they were explorers; setting off on an  expedition.  The challenge of the cycling and the wild, quiet, and relatively  unknown countryside ahead gives a great sense of anticipation.  The clients  start with 1 foot in the harsh Atlantic surf and finish with the other in the  mild Mediterranean calm.   This is a trip of a lifetime for people who will do  it. 
We believe it is a great value for a 10 day trip.  It is priced  in euros, as is our policy, but converted to $US at today’s rates is in the  $3300 range based on 6 persons.   You will note that the tour price can change  with group size – so more participation can lower the costs per person.   Also,  you will note that this trip can be done self guided too for about $2500.
