There are not any desert dunes in Indiana, but you can still enjoy sand boarding and sledding in the coastal dunes of Lake Michigan, not too far from Chicago. Please note that you are not allowed to sandboard in the areas within the Indiana Dunes National Lakeshore itself (most of which have vegetation in them), but you can find dunes for sand surfing in the areas surrounding it.
Indiana Dunes – Indiana Dunes State Park, Chesterton
Small dunes ideal for sand sledding, surrounded by nature and ideal to complement a quiet day out enjoying nature. You can slide in Kemil Beach but it’s not the best place – the dunes to the west of the park are best for sandboarding, as well as the area surrounding Mt. Baldy.
Mt. Baldy – Indiana Dunes National Lakeshore, Michigan City
Beach dunes surrounding Lake Michigan and located right on the border between the states of Indiana and Michigan. Dunes are somewhat short but steep enough to enjoy your ride without having to worry about hiking back on top. It’s better to slide down the lower dunes close to Lake Michigan rather than Mt. Baldy itself.
There are not any sandboard rentals available in the area, but some local surf shops have boards and sleds for rent, for instance Third Coast Surf Shop in Buffalo, MI. Alternatively, you can buy your very own sandboard or sand sled online.
