Some knowledge and confidence in riding machines is helpful, but not necessary. If you are physically able to move your arms and legs and can sit upright for 6-8 hours and can handle the cold, you can ride a snowmobile. There is always an option to share a machine for two people if someone in your group feels unsafe driving.  You will receive a short safety briefing on the operation of the machine prior to departure.  If you are unsure of your snow machine operating skills, you can opt for the snowcoach tour, which gets you to the same place in the comfort of an over-snow vehicle.
