Hello, I agree, you won't need a 4x4. We traveled the south coast and saw all the sights in a "regular car". Only one time would it have maybe helped, but honestly, I probably would not have used it if we had it. I'm not sure what the F-Roads are, but everywhere we went was easily accessible - except for the one I mentioned above. We just drove a bit slower and there was no problem at all. I hope you have a wonderful time. We absolutely loved it. Feel free to reply if you have any more questions about where to go or what to do.

The parking is not far. It is better to have good shoes and especially waterproof clothing or ... a swimsuit ;-)

Non un vero e proprio ristorante, credo una caffetteria ma non ci sono entrata e quindi non so dirti di più.

No, hay que pagarlo con tarjeta 700 puas te cobran por pelearte con mil chinos para sacar una foto y seguir un caminito como ovejas para verla, sin poder apartarte para disfrutarla a tu manera.

As others have said it is a short walk, maybe just over 100 yards. We were there in the winter and my wife was cold so she stayed in the car and we didn't pay. There is a small gift shop there. During the winter you can't go behind the falls as everything is iced over. Some people were trying to go up there even though there was a sign and chain to stop them. The steps were icy and I doubt they could get behind the falls. I took pics from the small bridge where the water flows.

Hey, it is possible but that would mean no stops until you get there. I would probably allow for a little bit more time which would give you time to stop for example on Hellisheidi. The waterfall is beautiful the later the evening gets because it is facing west. Have a safe trip!

The parking area has spaces allocated for tour buses and camper vans. Note there is now a fee for parking fee of 700 ISK per day.

Yes, a parking has been introduced. It is 700 ISK. It is automated and you need to use a card.
