What you'll see and do
Gross-Rosen Museum in Rogoznica
Gross-Rosen in Rogoźnica – the biggest Nazi-German concentration camp in Lower Silesia, with particularly harsh conditions and penal work in the quarries. The motto of that place was Vermichtung durch Arbeit (Annihilation through work). Around 40 000 prisoners died here: Poles, Jews, Russians, French and Hungarian.

Zamek Ksiaz w Walbrzychu
Ksiaz Castle – the third biggest castle in Poland, situated in the majestic rock cliff by the side of the Pelcznica River. Located 395 meters above the sea level and surrounded by a beautiful forest, the castle is sometimes called the Pearl of Lower Silesia. The castle's location combined with its size is not a common sight in Europe. In 1943 Hitler's paramilitary organization Tod began building one of his main quarters which, along with other objects of the Riese complex close the castle, near Osowka and Wlodarz, played a crucial role.

Why this scores 74
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
The secrets of World War II: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Wroclaw.
How much does The secrets of World War II cost?
+
Prices start at $179 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Wroclaw usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does The secrets of World War II take?
+
Plan for about 9 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Wroclaw is not rushed.
Is The secrets of World War II worth it?
+
It holds an Outty Ranking of 74 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 18 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Wroclaw, and how flexible the cancellation terms are.
Can I cancel or reschedule The secrets of World War II?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is The secrets of World War II suitable for kids and families?
+
The operator sets a minimum age of 3. Older children generally do well here, and families should factor in the 9-hour running time when deciding.
How far in advance should I book The secrets of World War II?
+
Around 6 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Wroclaw can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Wroclaw and add a light layer if any part of the 9-hour experience runs outdoors or after sunset.
Where does The secrets of World War II start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Wroclaw within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Wroclaw?
+
On Outty we rank every Wroclaw experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Old Town Wrocław Walking Tour, Auschwitz-Birkenau Tour from Wrocław, Wroclaw Old Town Guided Walking Tour. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Wroclaw?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Wroclaw?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
