Not exactly a secret, Seljavallalaug is one of Iceland's most iconic and distinctive hot pots. Nestled up against a rocky outcropping, hidden from view in a valley of the south coast, the hot pot is a unique and exciting experience for any Iceland traveller.
You shouldn't have too much trouble finding the pool, as it's a well known and frequented stop along Iceland's south coast, and luckily still not visited by the tour buses.
Take Road #1 from Selfoss towards Vik, about 85km from Selfoss, turn left onto Road #242 marked Raufarfell. Road #242 will fork, continue straight, following the signs for Seljavellir parking lot. The road will become a bit rougher and after a few minutes, it will end at a parking lot.
Grab your towel, swim suit and camera and continue on the walking path into the valley, along side a river. The walk is about 15 minutes on fairly flat ground.
When we went, we had to cross a section of the river as a makeshift log bridge had been washed away.
You won't be able to see the pool until you are almost on top of it, so keep following the path, past a big gray water tank and some piping.
The pool has a changing area but no shower facilities. Read more about Iceland's Hot Pot Etiquette.
We didn't find the water all that warm, so get a good spot where the hot water seeps out of the rocks and watch the clouds go by.
