I swear, this is the last of it, well almost. When I first went to St. Augustine, I thought it to be a very hokey tourist trap. Beyond the kitschy beach shops and seafood shacks (both of which I actually do enjoy!) is a wonderful historic gem.
This is my favorite house tour. It is the "oldest" house and has been in near continuous occupation since the Spanish. It shows the evolution of the town. You can see the basic house on the first level, the English addition with the second. While it has been restored, it once also bore the ornamentation of the Victorian era.
The Peña-Peck House
The Ximenez-Fatio House
And worth mentioning is the Fountain of Youth, in case your regimen is insufficient...
