Preperation

Preparation

A lot of sites will give the same initial information/warning. 
That it is probably easier to book most of the Russian trip through a Russian travel agent. Unless you can both speak Russian and know the intricacies of Russian bureaucracy. I know neither, so I spent some money with various companies.

I travelled with my partner in March/April 2017 as part of a large trip.

We are British citizens.

1,000 Korean Won was about £0.70p or 1 US$. 100 Russian Rubles was about £1.40p. I shall leave you to work out the costs yourself.

This trip can be completed in the opposite direction, i.e. Berlin to Seoul, but you will need expert assistance for the ferry crossing, Vladivostok to Donghae as DBS Ferries don’t allow personal booking from Russia.
Prior to arranging anything I had a good read of www.seat61.com

For the part of Seoul to Donghae this can be booked independently, however I used Nigel Sutherland, of Philippine Trails Ltd, who are based in the UK. 01700 502739

Donghae to Berlin I used Ms Irina Lazareva of Real Russia, who are based in London.

A Russian visa is required.

Both companies were excellent and tailor fitted the trips as I required. I would not hesitate to use both companies again.In addition to the Russian visa we are going by train through Belarus as part of the Moscow to Berlin 'Strizh' Express tarin. Therefore a Belarus transit visas is required.
