Cid Harbour is home to several bays, you can anchor in Sawmill and explore by tender or kayak if you hired one.
Joes beach, Naris Beach and Dugong are all great little spots to explore.
Make time for a bush walk to Whitsunday Peak (437 mtrs) is a fantastic hike for sunrise or sunset (5kms return). Take water and a pack up, comfortable walking shoes are recommended as the hike can be challenging in places, however the 360 degree views are well worth the effort. For the less adventurous a shorter, flatter walk exists from Dugong to Sawmill and return.
If your walking at sunset take a torch as it will be dark on the hike back to your boat!
Leave the lights on on board so you can spot your boat from the top!
