Welcome Pinnacle Lake!! Beautiful, corner lot. Your family will enjoy the 130 acre community lake that has excellent boating, swimming and fishing. Pinnacle Rock jutting out of the water is a sight to behold! Bring those SXS, atv's, boats and wave runners and make some memories with the family. Pinnacle Lake is a private, gated community about an hour from St. Louis making it easier to get to than some of the other lake destinations in Missouri.
