Missouri has more than 5,500 caves,
and some of the state's most scenic natural wonders lie beneath the
surface in caves. Onondaga Cave State Park is 90 miles from the St.
Louis Arch; the trip will take about one and one-half hours depending
on traffic. Go west on I-44 to Exit 214 (Leasburg). Head south on
Route H for seven miles. You will pass through the town of Leasburg.
The paved section of Route H ends in Onondaga Cave State Park just
before the visitor center. Do not cross the Meramec River.
A day-use area is available for
picnics. The picnic area is located along the Meramec River with
picnic tables and a charcoal grill at each site. The picnic shelter
may also be used if it has not been previously reserved. The picnic
shelter is located alongside the lake on the road to the campground.
Water and electricity are available as well as charcoal grills for
cooking and picnic tables. The picnic shelter may be reserved through
the park office for $30 per day.
Deep underground there is a world
that nature has created using water to form deposits of tall
stalagmites, dripping stalactites, active flowstones and many other
colorful deposits. Onondaga Cave, a National Natural Landmark, and
Cathedral Cave showcase these natural wonders, which can be viewed
up-close during cave tours.
There is also plenty of natural
beauty to enjoy above ground at the park. Vilander Bluff Natural Area
provides visitors with a panoramic view of the Meramec River. Come and
take a hike through the Meramec River valley, canoe or fish in the
Meramec River or enjoy a picnic lunch. Learn about the park's natural
resources above and below the earth's surface through exhibits inside
the visitor center.
The park is open year-round for
camping and day use.
