As mentioned. Overnighting on the BRP any where but in one of the CG is not allowed. However. the Parkway CGs are primitive, no electricity, No water, no sewer hookup. There are dump stations. and not very expensive. VERY quiet. During the week, and many weekends. you will have them pretty much to yourself.
As for fuel. NO!!! there is none for sale on the Parkway. You will have to get off to get it. Google Fuel on the BRP. there is a guide to fuel just off the Parkway.
Restaurants as well are just off the Parkway, and there are some really good ones.
