For ski hire we use and recommend Alan`s ski hire shop in Morzine. Here you can expect a great friendly helpful service from Alan and his team. We have been using them for our guests ski hire for over 12 years. You can expect to receive 40% discount on the price of the ski hire there. Don’t book on line though, but wait until you arrive in Morzine to get the full 40% discount.
