We had an early start with a trip to visit a tunnel eroded right through a promontory of sandstone.

There were trees which had trapped after floating in with the tide, and then slowly worn away. 

In some ways the most striking aspect of this visit was for us to emerge from the tunnel/cave and not immediately be struck by the beautiful sandstone wall opposite.

Next we had a trip up an inlet called something like: Rainforest Inlet (irony in naming?) which was very picturesque with wonderful rock “sculptures”, lovely mangroves, and a crocodile!

Some of the sandstone shapes are so striking because it is not obvious how they do NOT immediately collapse.

After a swim (where I received some good advice about how to improve my swimming technique from the other travellers), we visited another cave, this one not being a tunnel as there was only one real entrance. 

Once again I was struck by the way in which the sandstone can be eroded in ways to create extraordinary shapes, and even caves/tunnels through the rock.
