The Crown Point skatepark is behind what appears to be the Municipal Water Department. Built entirely of wood and skatelite, it is well-maintained, and looks like it was designed competently enough.
Beware of the weird hours they keep, though. They are:
Spring Hours (Beginning April 5th): Saturday and Sunday, 12:00-6:00 PM
Summer Hours: Daily, 12:00-8:00PM
This is also a pay-to-play park. Season passes (for non-residents) are $35; daily rates are $5.
Also beware: This park is available for RENTALS. If it is rented, that means: It is closed for everyone else for the day. With all these variables, it is probably best to call, before even going over there. The number is 219-661-2271; ask for Jennie Burgess. It was [of course] closed that day I visited, so I have no idea how it skates- Bud Stratford
