Beelitz-Heilstätten from Berlin: Which Day, Which Ticket, What You Can Enter

The RE7 pulls out of Berlin-Charlottenburg at 24 minutes past the hour, and 34 minutes later it stops at a small red-brick station in the pine forest south-west of Potsdam. Five minutes on foot from the platform you are standing under a treetop walk that runs straight across the roof of a ruined sanatorium, with pine trees growing where the beds used to be. That is Beelitz-Heilstätten, and it is one of the easiest half days out of Berlin.

It is also one of the easiest to get wrong this winter. The site changes its hours almost week by week until February, closes completely for two stretches in November and most of January, turns into an evening light trail from 27 November, and only lets you inside the old buildings on a guided tour in German. I checked every date, train and price on 19 October 2026, so here is what is actually open on the day you have in mind.

What Beelitz-Heilstätten is

Beelitz-Heilstätten was built from 1898 by the Berlin workers' insurance fund as a lung sanatorium in clean forest air, about 50 km from the city centre. It opened in 1902 with 600 beds and grew to more than 1,300, laid out in four quarters split by the railway and the country road: lung patients north of the tracks, other illnesses south of them, women on the west side and men on the east. In the First World War it became a military hospital, and one of the wounded soldiers treated here in 1916 was Adolf Hitler.

The part most people come for is what happened next. The Soviet army took the site over in 1945 and ran it until 1994 as its largest military hospital outside the Soviet Union. Erich Honecker stayed here from December 1990 until he was flown to Moscow in March 1991. After the troops left, the buildings stood empty, were stripped and vandalised, and turned into the most photographed lost place in Brandenburg.

The Alpenhaus burned out at the end of the war. The forest on its roof has been growing since 1945, and the treetop walk crosses right over it.

Which part you can actually visit

This is the first thing to understand before you go: most of the ruins are fenced and privately owned, and parts of the site are being restored for new uses. Walking into a building on your own is trespassing, and the operator reports break-ins to the police.

The part open to visitors is a 7.5-hectare section of the old park run by Baum & Zeit, entered through the restored gatehouse opposite the station. One ticket gets you three things:

• The treetop walk, more than 700 m of larch decking through the tree crowns, with a lift up to the path and to the 36 m platform of the lookout tower.

• The Alpenhaus, the burned-out women's ward with its roof forest, seen from above.

• The grounds, forest paths between the old pavilions, the long open-air rest halls and the expressionist surgery building of 1930.

The inside of the buildings is a separate ticket, and only with a guide. More on that below.

From above, the pavilions sit like islands in the forest, which was the whole idea of the 1902 plan.

The calendar this winter: one site, four different visits

Here is the part that catches people out. Between now and the end of February, Beelitz-Heilstätten is four different places depending on the date you pick:

• Until 29 October: open daily 10:00 to 18:00, last entry 17:00. Full daytime visit with tours.

• 30 October to 1 November: a Dia de los Muertos weekend, open 10:00 to 20:00 on Friday and Saturday and until 18:00 on Sunday, with the park lit after dark.

• 2 to 15 November, and 21 to 22 November: open daily 10:00 to 16:00, last entry 15:00. The site is closed from 16 to 20 November and from 23 to 26 November.

• From 27 November: daytime visits stop and ZEITREISE begins, a light and sound trail of about 90 minutes through the park, some of the buildings and up onto the treetop walk. Entry is from 16:00 in fixed time slots. In December it runs Tuesday to Thursday and Sunday with last entry 20:20, Friday and Saturday with last entry 21:40, and is closed on Mondays and on 24, 25 and 31 December. From 23 December it runs every evening through the school holidays.

• January and February: evenings on 1 to 3 January, a possible but unconfirmed extension from 5 to 10 January, then closed from 11 to 29 January. Daytime visits return on 30 January, 10:00 to 16:00, daily from 1 to 7 February and at weekends after that.

The dates come from the operator's opening hours page, and they can change at short notice for storms or events. The tool below puts all of it on one strip, so you can see the closed weeks at a glance, then click your date for the hours, sunset, trains and prices.

My advice: in November, the light is the real limit. Sunset moves from about 16:40 to about 16:00 during the month, and with a 16:00 close you have about four good hours on the path. Be on the treetop walk by 11:00 and you will not be racing the dark.

Getting there from Berlin

Beelitz-Heilstätten has its own station on the RE7 regional line, and the entrance is a five-minute walk from the platform. Until 12 December 2026 the RE7 does not run through the centre of Berlin, because the Stadtbahn between Charlottenburg and Ostbahnhof is closed to regional trains. That changes the trip:

• Weekends: one RE7 an hour from Berlin-Charlottenburg at :24, arriving at :58. Take the S9 or another S-Bahn west to Charlottenburg first; from Hauptbahnhof the whole trip is about 50 minutes, from Alexanderplatz about 55.

• Weekdays: the same hourly train plus a second one via Wannsee, arriving at :31. The S7 from Hauptbahnhof to Wannsee connects to it.

• Back: an RE7 leaves Beelitz-Heilstätten at the full hour, on weekdays also at 20 past. On a Saturday the last one is at 23:00, which matters on the late light-trail evenings.

From 13 December the new timetable starts and the RE7 should run through the city again, but the times are not published yet. Check them in the VBB app the week you travel. All the times above come from the VBB journey planner on 19 October 2026.

The ticket for the train: Beelitz-Heilstätten is outside the Berlin ABC fare zone, so an ABC ticket does not cover it. A VBB single from Berlin costs 6.30 euros each way, and a 24-hour ticket 12 euros. The Deutschlandticket covers the whole trip. My guide to train tickets for day trips from Berlin explains the regional tickets in more detail.

Tickets: the park, the tours and the evening trail

Prices on the Baum & Zeit ticket page on 19 October 2026:

• Day ticket until the end of October: 17 euros for adults, 15 euros reduced, 12 euros for ages 7 to 17, free under 7. A family ticket for two adults and up to four children is 42 euros.

• Evening tariff in October: 13.50 euros for adults from two hours before the cash desk closes, so from 15:00. Cash desk only, not on event days.

• Winter tariff from November: 13.50 euros for adults, 10 euros for ages 7 to 17, family ticket 35 euros. It does not apply on event days.

• ZEITREISE from 27 November: 19 euros online or 23 euros at the door for adults, 5 euros online for ages 7 to 17, family 42 euros. Each time slot has a limited number of tickets.

Online tickets are valid only on the day you book and cannot be changed, so buy them once you know the weather. Dogs are not allowed anywhere on the site, and there is no smoking outside the café areas.

The building tours: German, age limits and helmets

If you want to stand inside the old wards, a guided tour is the only legal way in. They cost extra and need the park ticket on top:

• Fascination Alpenhaus: 60 minutes, 12.50 euros, from age 7. The big halls of the women's ward and the traces the Soviet hospital left behind.

• Through the old surgery: 60 minutes, 12.50 euros, from age 12. Patient rooms, the operating wing and a bath hall in the 1930 surgery building.

• Surgery in full: 90 minutes, 17 euros, from age 12. The same building over two floors, with the X-ray rooms and the flower balcony.

• Tunnels and technology: 60 minutes, 15 euros, from age 12. The supply tunnels and the potato cellar under the site.

• History walk: 60 minutes, 10 euros, 6 euros for children, any age and step-free, with a short look into one building.

The surgery building opened in 1930 as the most modern lung surgery in Germany. The 60 and 90-minute tours go inside.

Three details matter for visitors. The public tours run in German; an English tour is only possible as a private group booking by email. Hard hats are compulsory inside and handed out for free. And tour tickets cannot be cancelled or rebooked, while late arrivals lose their place, so meet at the marked meeting point ten minutes early. Dates and spaces are in the operator's online shop, linked from the tours page.

If you do not speak German, I would skip the indoor tour and spend the time on the path and the grounds. The buildings make their point from above, and the photographs you see online were mostly taken inside places you cannot legally enter anyway.

How I would plan the day

Pick the date first, because that decides everything else. For a daytime visit before 27 November, I would take the RE7 that arrives at 09:58 or 10:58, walk the treetop path while the light is good, eat at the café by the tower or bring a picnic for the tables facing the Alpenhaus, and take a train back in the early afternoon. In November that is a calm half day; in October you can stretch it with a tour.

From 27 November it becomes an evening trip. Book a ZEITREISE slot online, take a train that arrives just before 16:00 or 17:00, and you are back in Berlin by about 21:00. The site is dark and cold by then, so dress for standing outside for 90 minutes.

If this is your first time in Berlin, keep Beelitz for day three or four, after you know the centre. My Berlin Then and Now walk from Alexanderplatz to Hackescher Markt takes about 2.5 hours, covers 11 stops and 16 places with an archive photo at each one, and you can book it here. For more trips like this one, my best day trips from Berlin guide compares the others, and when the RE7 timetable or the ZEITREISE dates change, my weekly newsletter is where I will say so.
