I am a huge fan of Monterey history and encourage visitors to avail themselves of the unique opportunity to enjoy CA's most historic city. Sadly, most of the historic adobes and other buildings are rarely open to the public due to budget cutbacks. Colton Hall is regularly open and a must see. The walk itself does not take that long, as Monterey is a very small town. If you don't mind seeing the adobes from the outside (sometimes the gardens are open such as the Larkin House) the path is a very good way to soak up the history of Monterey.
