Alhambra is part of the Helena Micropolitan Area, and its population is counted within the Clancy census-designated place.

Alhambra was a resort town situated south of Helena and relied on the heavy traffic when mining was important in the area.

Alhambra and Sunnyside Hot Springs were the two hotels in the town, together composing a medical and recreational resort that flourished the 1860s until the 1950s.

Although the water in the area was bottled and sold commercially and considered therapeutic in earlier years it was eventually found to be naturally radioactive and unfit for use.

[2] The days of Alhambra as a resort came to an end, though the area had already been in decline as mining production decreased.
