You can find an overview here.

Unfortunately, only regular lines run to the circuit. Apart from your own means of transport, you can just cycle to the circuit, take a taxi, or use the shuttle bus that your hotel often offers. If you want to stay close to the circuit all the time, we recommend staying at GPtents.com.

We recommend using the GPtents tented hotel, where they can prepare a tent and a comfortable bed for you. The campsite is very quiet, unlike the usual campsites at the races.
