How about The World’s Best Treehouse as a place to stay in the Blue Mountains in Australia? Nestled between two National Parks, it has a spa, shower, fully plumbed, fire place and stunning views of World Heritage listed rainforest.
Or this Cliff Top Cave located nearby:
These are two of the several interesting buildings that Lionel Buckett has built on his 600 acre property in the Blue Mountains in Australia. The prime bushland that’s been in his family since the 1950s was originally purchased for the timber, but thankfully Lionel’s use of the land is far more ecologically friendly. The buildings he has lovingly created are designed to have minimum impact on the area.
