This campground was very nice and clean and for a packed park was very quiet and we did not feel too close to the sites next to us.  We spent 2 nights here and went mountain biking at Imagination Glen Park in Portage just a few miles down the road which was awesome.  We stopped for a beer at Chesterton and Hunter's Breweries.  The sunset on Lake Michigan from the dunes was awesome.  We walked between the state and national parks.  This was originally a convenience stop along our route but I was impressed with the parks and everything there was to do, very glad we crossed this National Park off the list!

PROS: was very clean, well spread out, had a bathhouse, firewood and basics for sale.  Nice hike to the dunes and Lake Michigan with several trails to choose from.  There is also the Dunes-Kankakee bike trail that leads from the park and ties to the Calumet trail that also connects to several other trails offering miles of bike trail options.  Two dump stations made wait minimal.

CONS: not a whole lot, as is with most IN state parks there is no water hookup so you need to fill you tank up but it was set up really nice.

Did not really scout out an "ideal" site since they all seemed nice and pretty spread out for a state park.  I liked our end of the park that was close to walking path to dunes and beach.

NOTE: This was our second IN State Park campground(first was Clifty Falls) as part of out trip from GA to MN via TN-KY-IN-MI-WI-northern MN before staying in MSP for a week, then return via MN-IA-MO-IL-KY-TN-Home.
