Hawthorne Hills Park is located at 4880 HWY I.  Entrance to the park is north of Hawthorne Hills Golf Course and is shared with Pioneer Village and H.H.Peters Youth Camp.  The park is open to the public year round, with daily hours from 6:00 AM to 9:00 PM.   The 57.1 acre park area is mostly undeveloped woodland that is sandwiched between Pioneer Village to the north; Herbert H. Peters Youth Camp to the east; and Hawthorne Hills Golf Course to the south.

There is a roadway that takes you to the center of the park, where you can park and enter the hiking trails that traverse the east end of the property.  Dogs and cats are allowed only if they are cleaned up after.  The east side of the park has access to the Milwaukee River where you can enjoy the view or fish.  There are no amenities at this park other than a few grills and picnic tables.  Fires are allowed only in the grills provided. 

On the south side of the park, across from the asphalt roadway, there is a pond that is also open to fishing. This pond does not allow boating due to its proximity to the golf course, and entry to the course grounds are strictly PROHIBITED.  Due to the minimal development and mature forest canopy, bird watching can be very rewarding, one may even catch a glimpse of an osprey or bald eagle that travels the river corridor.
