If I were to do it again, I would stay in Port Douglas or Palm Cove or one of the other local resort destinations.
On Saturday we did a tour that included a ride on a scenic railway up into the Kurunda rainforest village and a skyrail tram back down. The train is lovely and SPie enjoyed it. I was looking forward to the the skyrail tram and it didn't disappoint. I appreciate that the skyrail is a way to view the forest without doing any damage to the area and the views are great. The tram makes two stops on the way down the mountain where you have the option of getting off and walking along boardwalk paths to lookout spots to a waterfall and the forest valley.
If I had more time, I would have also liked to hike one of the Daintree trails. The tour we did was good and I recommend it, but it definitely wasn't an "up close and personal" type of experience.
We ended the weekend by visiting the Botanic Gardens in the morning before our flight home. SPie was on the lookout for butterflies everywhere, so the butterfly sanctuary definitely made an impression on her.
One thing we didn't do was an excursion to the Great Barrier Reef. The tours were long and not exactly toddler friendly, so we decided it was best to skip it.
It was a good weekend, but I think this is one area we'll need to revisit when SPie is a little older (or maybe when she's away at summer camp). Maybe by then I'll be in need of a new beach bag too.
