Probably 30-40 minutes

Best advice, contact thepark setvices. They will have up to date info on boat launching sited and fishing information.

Gros morne is on the west coast of newfoundland

Check the park map, they may be in the legend, unsure though!

Yes you must book with park regardless of style. They will also inform you of any other rules.

Hiking. Relax on the beach. See the sights and enjoy tbe seafood.

I don't believe they allow pets inside.

The park is always open. The Visitor centre at Rocky Harbour opens at 8.00 am and the discovery centre at Bonne Bay at 9.00 am. You can buy tickets there and there are ticket boots at most of the entrances
