Port Douglas is located 70 km North of Cairns, or just over an hours drive. It's a popular spot due to it's village feel, it's proximity to the Great Barrier Reef and the Daintree Rainforest.
I stayed out of town at the gorgeous Niramaya Villas, located about 4 km out of town.
The villa was self catered so I ate in most nights but I did eat out for lunch
Walk up to the lookout at the town end of four mile beach
