Fodor's Expert Review Sulphur Springs Park
As you approach Sulphur Springs Park and the crater of the "drive-in volcano," your nose will pick up a strong scent emanating from more than 20 belching pools of murky water, crusty sulfur deposits, and other multicolor minerals baking and steaming on the surface. You don't actually drive all the way in. Rather, you drive within a few hundred feet of the gurgling, steaming mass and then walk behind your guide (whose service is included in the admission price) around a fault in the substratum rock. (Don't worry ... the volcano hasn't erupted since the 1700s, probably because it continues to let off steam.) Following the fascinating, educational half-hour tour, you're welcome to take a quick dip in the nearby hot, mineral-rich bathing pools—they can also be pretty stinky on a hot day, but your skin (and joints) will thank you! You can rinse off under the waterfall.
