Saba's Sulfur Mine: Into 'The Great Hole' Above Hell's Gate
An abandoned 19th-century mine tucked into the cliffs of Zion's Hill, reached by a short, steamy hike with airport-runway views.
Why Go
Most visitors come to Saba for Mount Scenery — but wedged into the lower slopes above Hell's Gate is a rawer, stranger piece of the island's story: a Victorian-era sulfur mine you can still step inside, if you bring a guide, a headlamp, and a tolerance for heat.
The Experience
The Sulphur Mine Trail begins at the end of the paved road in Lower Hell's Gate (Zion's Hill) and drops through scrubby coastal terrain with wide-open views of Green Island, the Atlantic pounding the cliffs below, and the impossibly short runway of Juancho E. Yrausquin Airport. In about 45 minutes round trip on a moderate path, you arrive at the mouth of the McNish Sulfur Mine — a dark opening in the rock that locals call 'The Great Hole.' Inside, the air turns thick and hot, the walls sweat, and the faint tang of sulfur hits fast. It's a short, atmospheric detour that stitches together seabird colonies, sea cliffs, and industrial ghost-town texture in a way nothing else on Saba does.
What to Try
Book the guided mine entry through the Saba Conservation Foundation — the exterior is dramatic, but stepping into the tunneled chambers with a proper flashlight is what people actually remember. On the way back, linger at the overlook for the seabirds nesting on Green Island.
Insider Tip
You are not allowed to enter the mine without a guide — call the Saba Conservation Foundation at +599 416 3295 in advance to arrange one. Bring a real headlamp (your phone won't cut it), wear closed-toe shoes you don't mind ruining, and don't stay inside longer than 15 minutes; the heat and humidity build up quickly and there's no ventilation.
The Practical Stuff
Trailhead is at the end of the paved road in Lower Hell's Gate / Zion's Hill. Round trip: ~45 minutes, moderate difficulty with some loose footing on the descent. The trail itself is free; guided mine entry has a small fee through the Saba Conservation Foundation. No facilities at the trailhead, so carry water. Go in the morning before the sun bakes the exposed slope, and skip it in heavy rain when the path gets slick.
