Those 3 checkpoints do not allow to cross the border on foot.
Mamonovo/Gronowo and Nida/Morskoe have bus options.
Mamonovo - it's better to take a bus in Elblag or Gdansk, could be too tricky to try and catch it near the border.
Morskoe - you can try to catch a bus there, but still - Zelenogradsk or Kaliningrad is a recommended starting point to avoid the ...
Your best choice seems to be Trans-Exim that operates two times a week.
The ferry line Ust Luga (Saint Petersburg) - Sassnitz (Germany) - Baltiysk (Kaliningrad) has come instead the previous one (valid from 2001 till 2007) “Saint Petersburg – Kaliningrad – German ports”.
The Ust Luga port is located in 150 km from Saint Petersburg. The port Baltiisk is ...
As you say you're going to pass the border at Curonian Spit, you'll be in Klaipeda before this. @Marcel C. already said about the Nida station, but I want to add some information which can be useful for you and others who will view this question.
So, you have two different ways to get from Klaipeda to Curonian Spit and Kaliningrad with your car:
As @Marcel ...
According to a post on TripAdvisor by JeenaB who is from Kaliningrad tickets are only available at the station. There are 3 buses, one at 6:30am, 3:30pm, and 5:00pm. JeenaB states that the buses are rarely full so there shouldn't be anything to worry about. So it looks like the only way to get a ticket is at the bus station, but there shouldn't be any ...
Since the 72 hour visa is only available to the EU countries, UK, Switzerland, and Japan. Which means that the rest of the people will have to enter under the regular tourist visa.
There is also agreements being put in place regarding multiple-entry visa, so I would just apply for that and use it to enter both Kaliningrad and St. Petersburg.
Or you could ...
There is a border crossing from Lithuania to Russia on the Curonian Spit. It is just south of the village of Nida. You can see the station via the google maps satellite view.
If you are not a Russian citizen, you need a Russian visa. This has to be arranged before going there. They won't issue a visa at the Nida border.
I really don't recommend trip suggested by @Geeo. Cabin really exists, but they are not designed for tourism - much more for expeditors and workers on ship. And you have nothing to do on ship right until the end of your trip.
Other thing is that you have to firstly go to the Baltiysk on bus or train, and even if you come to Ust`-Luga(small town near the ...
I have done that trip in the other direction, but you are not allowed to cross the border by foot. I cannot comment on entering Kaliningrad Oblast from Poland by foot, as I have taken the bus from Gdansk. It seemed more difficult to enter Russian territory than to leave it in a slightly unusual way. Nick's tip on an alternative border point might be worthy ...
VMAtm made a perfect answer about Kaliningrad, here are my two cents about Curonian Spit.
First of all, for me the Russia part and Lithuanian part do differ a lot. On the Russian part you could find:
Ornitological station, where you could see how ornitologists catch birds during their season migrations and put rings on them (last years you need to book a ...
In most cases you can buy tickets before departure. But there can be problems during russian holidays.
At least 4 dayly buses are available from different companies.
And only one company offers you online booking: http://ecolines.net/
On the same site nothing is indicated whether the entry and exit points must be the same. The only thing that is prescribed on the official site are the points of entry, which given the fact that Khrabrovo Airport is on the list of possible entry points means that the origination country doesn't have to be Poland.
There is a tourist site konigsberg.ru ...
No. Since the final destination is not a third country, this does not even begin to fulfil the TVOW requirements presented in the question. You must enter and exit the region directly and not transit anywhere else in Russia.
Also, generally when you have a stopover in the same country as your final destination, immigration formalities are processed on the ...
No, you cannot enter Kaliningrad by train, as the only operational railway checkpoint (Chernyshevskoye) is not listed as an approved port of entry.
RZD has no say in this, and so no authority to allow or prohibit it.
So you need to enter by air or bus/car
E-visa isn't valid for trains, unfortunately. Official reason - no mobile scanners available, as the border check is done right on the train. Which doesn't make a lot of sense, as basically the same system was operational during the FIFA World Cup 2018.
There are plenty of bus options available. And even a unique option to cross the border on foot. :-D ...
We had some bad experience with that before. I called local Belavia representative, and he said, you will get all stamps if you show Belarus visa or transit ticket. It's required to board that plane.
Note that you can't use visa-free entry thing by taking a plane from Russia:
The given order of visa-free movement through the airport does not extend to ...
I completely changed my itinerary, and I had no problem (Swiss passport here). Nobody ask me the reason of the change.
Just keep the new itinerary dates within the expected dates, and do not change the purpose.
Private taxi transfer
connection in Gdansk or Elblag

I don't know about any successful story about crossing the border using a car rented in Poland.
Just a small reminder that this answer is time limited in relevance: for current travel it is only very limited in possible application - don't take this as advice that it is possible to do this all the time without visa, you'll get a lot of problems.
Even though there are negotiations about implementing mutual visa-recognition between the Union State ...
You can find a guide in the local tourist information center: http://www.visit-kaliningrad.ru/
And there are several books in Amazon about Kaliningrad in English: http://www.amazon.co.uk/s/ref=nb_sb_noss/276-9024839-7416712?url=search-alias%3Daps&field-keywords=kaliningrad+guide
