Jewel Cave National Monument

Just a few kilometers west of Custer is one of the largest cave systems on earth. With more than 360 kilometres of explored corridors (and new ones are added each year), Jewel Cave is one of the longest caves in the world.

It owes its name to the glittering calcite crystals that cover many walls and sparkle like gemstones in the light of the lamps. Unlike Wind Cave, huge halls, shimmering crystal formations and impressive dripstone landscapes impress here.

Since Jewel Cave and Wind Cave are completely different cave systems, it is worth visiting both parks.

The access to the visitor center is easily possible with larger campers. However, if you visit several sights in one day, the pickup truck is much more flexible.

Book your guided tour as early as possible. Especially during the summer holidays, many tours are already booked out in the morning.

In the cave light conditions are difficult. A camera with good performance in low light or a modern smartphone usually achieves better results than a camera with flash.

Without a guided tour, no access to the cave is possible.

Also wear a jacket in summer – in the cave there are around 10 C all year round.

Wear comfortable shoes with good grip.

Plan enough time for the visitor center and the Roof Trail.

Jewel Cave is one of the great secrets of Black Hills. Although it is among the longest caves in the world, many travellers overlook it for the sake of the more famous sights. This is why it's often much quieter here than at Mount Rushmore or Custer State Park.
