Merrillville Tourism & Sightseeing

The greater Merrillville area is home to The Indiana Dunes -- featuring 15 miles of Lake Michigan coastline and 120-foot sand dunes in the Portage and Chesterton areas. Visitors to the dunes often come into Chesterton and Valparaiso for great dining and shopping. And with great hotels and bed & breakfast inns located near the beach and in the quaint towns, Indiana Dunes Country is a great place to enjoy a vacation and then take day trips to Chicago or Amish country.
