From the Gilhams Beach Camping Area, you can walk over to the sandy beach and watch the sunset, or take a beach rod and try your luck at fishing.
This site has flushing toilets, there is a water tank but make sure you boil the water first. A nice grassy area for you to set up camp and the beach nearby for sightseeing and fishing.
Grants Lagoon Camping Area is a nice Bush camp with some drop toilets inside the Bay of Fires Conservation Area, with a boat ramp if you need it, plus it's a nice kayaking area as well.
