The official guides of La Grave (www.guidelagrave.com/english/index.php) come highly recommended. They are all locals and all highly qualified. You can visit their office in La Grave or at the Maison du Montagne (a block from the tourist office) in Grenoble which has an office of the Guides de Haute Montagne from La Grave in it where you can book guides. Another option is the English speaking guides at www.skierslodge.com who are also locals and can offer accommodation and transport as well as guiding.

In general mountain transport is not needed in the Ecrins Nord area as the lifts give such good access to the alpine terrain. In addition, heli-skiing and heli-drops are not allowed in the French Alps.
