Getting around Guernsey by car gives you the greatest flexibility for discovering the island at your own pace. Make sure to take the roads at a relaxed island pace, as the maximum speed is 35mph on bigger roads.
There are two rental car companies based at Guernsey Airport - Hertz and SIXT. Their desks can be found in the main concourse of the Terminal building. Upon arrival, a representative will meet you in the arrivals hall and guide you to your vehicle, which is located on-site for convenience.
