For trips west into Kham, groups might consider booking an SUV (越野车; yuèyě chē) with a driver. Given the high cost of gas and the challenging road conditions, rates are generally high, starting at ¥850 per day including tolls and gas, but excluding food and sleeping costs for the driver. Add at least an additional ¥150 per day if the driver speaks English or Tibetan.
Most of Chéngdū's hotels and hostels can assist with finding a reliable, properly insured driver. Before embarking, settle on the itinerary, fee and what it covers, and what happens should the car break down or some other unpredictable, trip-altering problem arise.
