I was hiking in search for birds in the area so I did not take any transport at all. Please check on Reykjavik websites and I am sure you will come up with something. Have a nice trip!

I passed by the place on a random walk and I have no idea about their opening time. When I was there, I did not see any people though. Sorry I cannot be of much help. May be you can try to search on google. Have a great time when you visit.

I don't think so/ I think you pack your own... and folks had back packs- and they had swim suits on, and they ran into the colder water from the thermal too!! Yikes - it looked like you were on your own basically, not structured like the Blue Lagoon.

We had a rental car, a map- and just explored- it was closer to the city then we thought ....

Yes, plenty, there's parking at the marina and even if that was full, there's parking at the university a 5 mins walk away.

They can accommodate small bags but there no real room for full size luggage. Check the hours of operation as they are limited and the facilities are quite small. Cheers

Yes it opens in October, there's one or two weekdays when it isn't open, check the site. Hot pot and cold sea ... Enjoy Btw it costs 600isk outside of summer
