Treblinka Poland

No, definitely not on a train line...your only choices are renting a car or hiring a driver or taking a tour. By the way, driving outside of Warsaw is not difficult. Alternatively, many folks on this forum highly recommend the services of Andrew Durman (you can Google his info).

"Treblinka remains a backwater town, and as such travellers are going to struggle to reach it. Put simply, either hire a car and fire up the GPS, or contact a Warsaw-based tour companies, most of which will be happy to tailor a visit for you. Alternatively, hire a six person minibus for 250zł – call 604 89 63 97 for further details."

Thanks Agnes.

I would recommend that you contact Andrew Durman to guide you. We spent several days with him last summer and he is phenomenal! Andrew is passionate about his country, a wealth of information and his prices are incredibly reasonable. We left Poland with a new friend! His services are in great demand and he books up early. http://tour-service.pl/index.html

Trains go as far as Małkinia Górna (1h 10m or 1h 35m) and that town does have taxi operators to cover the last 5 kilometers. (I don't know anyone who's tried that.)

I visited Treblinka with a private guide. I didn't pay much attention to how she got there, but it seemed off the beaten track, certainly not in a town. Another thing to consider: The displays in the small museum/visitor center there had very limited English attached. My guide was able to give me a much better understanding of what happened at Treblinka than I would have been able to glean from the displays on my own. She also asked them to show me a video of a survivor that I would not have been aware of. The cost of my guide's services was well worth it.

Has anyone had any problems through TSA carrying smart phone battery packs in your carry on luggage?

You might want to post your question re battery packs under “General Europe” rather than “Treblinka Poland”. You would probably get more responses.

Tom,

Spare batteries (Lithium Ion) that are not in the device they are designed to power must be transported in carry on luggage, and can not be checked. I always make sure the terminals are covered with electrical tape and each battery is in a plastic bag.

I've visited Treblinka but travel by motorhome. As someone else said it's a "backwater".....pretty damn remote and you need wheels to get there! I will always remember it for two things. At the end of the road approaching Treblinka i spotted a Garage with the lowest priced fuel i'd ever seen in Poland.....and i'd got a full tank! No problem, fuel is cheap anyway in Poland.

The other i remember, the weather was absolutely boiling hot and half way round the site i got bitten on the leg by a horse fly or something. Whatever it was i couldn't stop the blood pouring so had to go back to my van to get it covered over!
