Just a ferry trip from Cleveland over to Dunwich. When in Dunwich why not check out the museum. Or if you want free adventures go to Blue Lake or Brown lake. Blue lake is a hike to get to and the sign to find it along the main road isn’t too obvious. Brown lake you can drive up to the water and can go on an adventure around the lake with great tranquility.
If you want to go surfing or just walk along the water why not check out point lookout! They have amazing gelato at the end of the gorge walk. And whilst doing the gorge walk look out for the marine life.
Finally amity point is the place to check out if you want to fish and has great camping places.
