City to Caverns
Starting from St. Louis, heading west on old Route 66, embark on the day long journey from the eastern border of Missouri to one of the most epic attractions along The Mother Road. Prior to departing, be sure to soak up the sites in St. Louis, like the Gateway Arch and of course indulge in some Ted Drewes Frozen Custard from the iconic Route 66 stand. Heading southwest out of downtown, follow the old road along Gravois Avenue, Chippewa Street, and Watson Road, just south of the parallel I-44 freeway. Continuing southwest, hop on the I-44 freeway until at least Eureka, and along the way stop at the Route 66 State Park and visitor center to stretch your legs and to see the state park’s picnic sites and bike trails. Just 40 miles from the Gateway Arch, the town of Gray Summit houses the stunning wildflower meadows of the Shaw Nature Reserve. Just before Shaw Nature Reserve, Route 66 reemerges winding its way westward. For the majority of 30 miles between Shaw Nature Reserve and Meramec Caverns old Route 66 is again overwhelmed by the I-44 freeway, so save your Route 66 exploring for another day and head west on I-44 towards the caverns you’ve been waiting for. Rejoice in fun for the whole family at the renowned Meramec Caverns!
