We have July 10-29 available to do a road trip next month, leaving from St. Louis. Any suggestions for a last minute plan? We are pretty open as to where we can go! We have three kiddos ages 9-11. We love to hike, see national parks, spend time at beaches/rivers/waterfalls. We also love cities and museums. We won’t bother with amusement parks. I’m thinking somewhere that won’t be blistering hot... We’re not afraid to drive :) We’ve driven to Maine and down the east coast from here. We’ve also already done Rushmore/ Badlands and Cuyahoga. 8 hour days are usually the max for driving. We love to camp and would like to do a trip as economical as possible. Thanks for any ideas!
