Magic Carpet Golf closed its doors in December 2007. On January 26, 2008 the owner opened the locked gates and allowed members of "Vanishing Tucson" to come take one last look. There are talks and plans underway to save many of them, possibly relocating them at Valley of the Moon or perhaps placing them in neighborhood parks.
I'll post more information as it comes available.
It's a 100 foot climb to the top of Tiki. On the day of our visit, the stairs were blocked.
