The Mammoth Site
The Mammoth Site preserves an active paleontological dig where 61 mammoths died 26,000 years ago, creating one of the world's largest mammoth research facilities. Visitors observe ongoing excavations from elevated walkways, while guided tours explain how the animals became trapped in an ancient sinkhole. The museum displays mammoth bones and Ice Age artifacts, and the research laboratory allows viewing of fossil preparation. The site's active science, educational programs, and unique subject matter make it fascinating for reunion groups interested in prehistoric life and paleontology.
SCOUT LOGISTICS
Adult admission is $14 and groups of 10 or more pay $12 per person when reservations are made at least 1 week in advance through the education office. The museum building and active dig site viewing area are fully ADA accessible with ramps and an elevator to the observation walkway. Hot Springs is located 60 miles south of Rapid City via Highway 79 and Black Hills driving distances mean you should allow 75 minutes travel time each direction.

Wind Cave National Park
Wind Cave National Park protects one of the world's longest caves featuring rare boxwork formations, along with prairie and ponderosa pine forest ecosystems above ground. The cave tours explore passages decorated with unique calcite formations, while ranger programs explain cave geology and formation. Above ground, the park's mixed-grass prairie supports bison, elk, and prairie dogs, and hiking trails explore diverse landscapes. The park's combination of underground wonders and surface wildlife makes it ideal for reunion groups seeking varied natural experiences.
SCOUT LOGISTICS
Cave tours range from $10 to $15 per adult depending on difficulty and groups of 10 or more must book through recreation.gov at least 2 weeks ahead as tours cap at 30 people. The visitor center and surface prairie trails are ADA accessible but all cave tours involve stairs ranging from 150 to 450 steps with no wheelchair access underground. The park connects to Custer State Park via Highway 87 and driving between the two takes 25 minutes covering 12 miles of winding Black Hills roads.
