Coming up next week from Illinois to a house in New Buffalo. Looking at the lake temp, it will be too cold to swim, seeing readings of 63-72? What else is there to do up the there? My wife and I are avid cyclist so we will be bringing our road bikes, but we have a 15 year old that is coming as well and she will be bored out of her mind. Is there any waterparks near there. Searching the interweb all I am seeing is the dunes state park. Also, looking for cool place to eat and drink. Thanks in advance!
