Netflix has a good documentary with 2 survivors of Treblinka. Most of you probably know this was arguably the worst of the camps in terms of extermination numbers in a short span. The documentary is called Death Camp Treblinka: Survivor Stories and it is currently available on Netflix. There was an uprising at the camp and many people escaped. Treblinka is one of the camps I visited on my Holocaust trip. It was one of the most powerful experiences I had. Its just a spot, in the woods.. in a beautiful forest. Nothing remains of the camp. Its so hard to believe how many people were murdered there in 14 months.
