Haunted place hike near Oranienburg (15km) with Café at the end ☕

Just in time for Halloween, we’re heading to one of the eeriest lost places in Brandenburg: the abandoned Grabowsee sanatorium. Hidden in the forest by a quiet lake, this former lung clinic has stood empty for decades. Its crumbling red-brick wards, ivy-covered facades and silent corridors are so cinematic they’ve been used as a film set for horror movies and Hollywood blockbusters, including The Monuments Men. On a grey late-October day, it doesn’t get more atmospheric.

The plan:
10:00 — Meet in front of Oranienburg train station 👉 https://maps.app.goo.gl/qT83XCBzn2wgZZkV6
How to get there: Take the RB32 train to Oranienburg from Ostkreuz at 9:18, or use any other option that works for you.
10:00–13:00 — We hike through the forest to Grabowsee (with a break for lunch/snacks)
13:00–14:30 — We explore the sanatorium: the old clinic buildings, the chapel and the overgrown lakeside grounds. Entrance: 10€, cash on site (an additional fee of 10€ is usually asked if you want to take photos)
14:30–16:30 — We hike back to Oranienburg. After reaching the city, there will be time for a well-earned coffee & cake ☕ before the train
17:29 — We come back with the RB12 to Berlin Ostkreuz (or you can choose what works best for you)

What to bring: sturdy, comfortable shoes, warm layers and a wind/rain jacket, a torch (optional), and cash — at least 35/40€ (10€ ticket + 5€ meetup fee + some extra for the optional cafè/ photo permit). Bring water and your own food/snacks.

Organizing fee: 5€ (cash), collected at the start.
