About 30 miles south of Niagara Falls, just below the Canadian border in northwestern New York, inside Shale Creek Preserve about a half-hour drive south of Buffalo, lies a hiking trail with an unusual payoff, if you can find it: Eternal Flame Falls, a waterfall tucked away in a grotto that contains a natural “torch” about 8 inches high.

The ground at the base of Eternal Flame Falls emits a steady supply of natural gas, which rises from deep below the surface up through fault lines and into the open air. This, in turn, is what lights the flame, found on the waterfall’s right-hand side about 5 feet up from the creek bed.

The flame is visible year-round, but the waterfall can run dry in the summer and often is only fully flowing in the spring. If you go right after there’s been some decent rainfall, you’ll get to enjoy the waterfall’s full effect.

The flame stays lit on its own, but bring a lighter just in case — occasionally it goes out, in which case it’s your duty as a good citizen to relight it. It ignites quickly, with a distinct “pop,” so maybe try one of those extra-long candle lighters if you’re nervous.
