Hwy 21 South to Elephant Rock State Park

Motorcycle Type : Sport - Touring

Hwy 21 is very nice. But if you want a diversion with tighter twisties and good pavement, I enjoy jumping off at Potosi (West on Rt 8, a good place to get gas) and then immediately turning left onto Hwy P heading out of town. This will turn into Hwy DD. Turn left at Hwy 32 which will take you back to Hwy 21 just North of the park.

Very nice ride with quite a few hills and nice scenery. Minimal traffic (except around Hillsboro and Potosi). Try it in the Fall when the leaves are changing - good stuff.

Hwy 21 actually starts at the intersection of Gravois Rd (Hwy 30) and Tesson Ferry Rd. in Affton, MO, near Grant's Farm. Long known as "Blood Alley" due to the hilly (frequently blind) turns and heavy traffic, it's mostly been tamed by replacing it with a four lane limited access highway from Lindbergh Blvd (US 61/67) in S. Saint Louis County to Hillsboro in Jefferson County (about 26 miles). However, the old Hwy 21 still exists. Heading southbound, take the "Old Route 21/Meramec Hts" exit just past Hwy 141. The "official" Hwy 21 rejoins in Hillsboro at Route B. And if you're feeling adventurous, Hwy 21 continues another 115 miles to the Arkansas state line, where it turns into Arkansas Hwy 115.
