If you're prepared to drive to Oak Creek, this location is one of the lesser-known abandoned sites. I had to look long and hard to find this place... You can tell me for yourself if you think it's haunted.

Have you been to this abandoned house? What did you think? Leave any tips of your own or observations in the comments to help other explorers!

The fact that it's an Insane Asylum just makes this abandoned structure all the more cool. It's not a huge area to explore, but it's great for dramatic photography. Just be careful not to get caught - this place is one of the most likely to get busted (if you're not smart about it).

Park wherever you want - people live in the apartments surrounding this site, so anywhere you go won't be suspicious. The asylum is the building in the center. Use only low-power flashlights because bright ones (such as the iPhone flashlight) are very obvious from the outside and can cause onlookers to call the police. Go at night or early morning to avoid people entering and leaving the apartments.

​If you're afraid of heights, keep scrolling: this site marks the highest climbing structure I've been to. Climb a 30-foot ladder to the top of an old grain mill to see the blaze of city lights all around, then climb down to investigate the eerie glow of old boating buildings and other, less impressive towers with plenty of low roofs to traverse and a low threat for other explorers. Make sure you stop by the abandoned parking lot before you leave to add to the graffiti wall.

Park near other cars just to be safe and walk the majority of the distance. Travel with purpose and you will probably not be questioned.

Park in Tall Oaks Court and walk across South Racine Avenue to the school. DO NOT PARK at the school itself. Police monitor the roads and will arrest any car that appears to be investigating the site. You should be able to see it easily on Google Maps, but if not, the coordinates are 42.947797, -88.15724. The easiest door to open is the one around back across from the Spongebob graffiti. If it sealed by the police occasionally, but there are so many trespassers that it is usually cracked back open before long. If there is a rock or other large object in front of the door, it means there is no one inside because someone had to place that object there from the outside.  

There are three floors, only two of which I have explored. When you first walk in, you can either go up the stairs or down the hall to a door. This door doesn't open. It leads to the basement where a local cult practices human sacrifice. Don't go that way.

The staircase should take you to the rest of the school. There is a gym, two levels of classrooms, a cafeteria, etc. If you're lucky, you'll find some cool artifacts from when Prospect Hill was open. If not, you'll still be scared out of your mind. Keep an eye out for my name written in graffiti.

Because the building was so dangerous, it was closed in 2007. It can't be that dangerous, though, because it's still standing - 9 years later.

If you're coming at a time when the museum is closed, walk around to the left side and climb down the side of the stone wall. It shouldn't be that difficult... if you're having trouble, you're doing it wrong. From here you should have access to the lower garage, outdoor terrace, and gardens. If you're good at climbing, you can probably get to the roof as well (and therefore, the inner terrace). Leave the way you came or hop the fence at any point.

This route is the easiest and least fun way to access the quarry, but it will get you there. Park in the end of the neighborhood on Waynescott Road and enter the woods to the left of the house with the American flag. There should be a trail to follow that will take you right to the water. You'll have to pass a "No Trespassing - Private Property" sign, but that's how you'll know you're going the right way.

Park at the Ridgewood Baptist church at 2720 Lilly Road and enter the woods near the "No Trespassing - Private Property" signs. If you weave through the woods, you should find a trail that will take you to the upper ridge of the quarry. You can walk the entire distance around the lake (1 mile) on this path and there are a few treacherous routes from the rim down to the water if you want to go in. This route is by far the hardest and longest way to get to the water - courtesy of the boys' cross country team circa 2014.

There's usually no one patrolling this site, but sometimes they pay a teenage guy in a kayak to sit in the middle and yell at trespassers. Every person I've encountered is pretty friendly and will let you off the hook if you just apologize for being at the site and promising to leave. You won't get in any trouble unless you're bringing in illegal substances.
