Want to see a couple of neat geysers, hot springs, and a hot lake from the comfort of your car (or with minimal walking)? Or are you simply enjoying the many thermal features Yellowstone has to offer? Then Firehole Lake Drive is for you. (Not to be confused with Firehole Canyon Drive - which is pretty and runs along the Firehole River including it's cascading falls.)
Firehole Lake Drive is a simple, 2-mile, one way road located in the south-western section of Yellowstone between Midway and Lower Geyser Basins. Drive it and you may find surprises waiting for you... pleasant, visual surprises - and all coming one right after the other - with the added benefit (for some) of no hike or elevation change required to see them at their best.
Surprise Pool is one of those deep blue, gorgeous pools found right at the beginning of the drive. A little further down, some might be fortunate enough to see Great Fountain Geyser erupting (we weren't, but the "base" for it is still impressive).
Continuing on, is a geyser that is incredibly unique in its look - and a reason alone to make this 2 mile detour - White Dome Geyser. We DID get to see that one erupt - it looked picture perfect! You'll also instantly know why it's named "White Dome..." Intervals between eruptions here are generally only 15-30 minutes, so it is worth a wait if you aren't fortunate enough to see it right as you drive up as we were.
Another short drive and you're at Pink Cone Geyser - another we saw erupting... and another appropriately named... Near the end of the drive the road goes between Hot Lake and Firehole Lake. You can stop here (and at all those other spots)... as there are boardwalked short trails allowing you to see the lakes better - and see a "hot cascade" that flows into Hot Lake. Colors vary.
This drive doesn't take long - most of the time is spent looking at the features - and some of these features - esp White Dome Geyser just aren't duplicated elsewhere. You could drive on by on the main road missing it all, but why would you? You've lost little time by taking this 2 mile detour - well, unless you get "hooked" watching a geyser erupt! Besides - didn't you come to Yellowstone to see such things?
