Like a few people have said a small fee to enter we paid 400 Iceland korona each, you can walk all the way around the top and then go to the bottom to the lake, when we visited the lake was frozen so we could walk all the way round it at the bottom and on the top so was very lucky. If you love a photo as you can see with mine on a clear sky it's lovely to see the sky change colour we visited around 3/4pm. Enjoy.

We added Kerid in as a stop on the route between Selfoss and Laugarvatn as we wanted to see a range of features and landscapes on our trip. Though this was the only 'natural' place we visited which we had to pay an entrance fee at, there was no complaint at paying as the pathways were well maintained and there were areas marked out for conservation so it was good to see how the fee contributes to the experience. We walked a lap around the rim of the crater which gave us fantastic views of the nearby area, and an deceptive view of the crater below. The info boards at the top were also great to read. After walking to the bottom of the crater we found the pool/lake thinnly frozen. There were people skimming stones across the ice which made an unearthly echo! It was so different to compare the scale of the crater from the bottom- so almost two different experiences. This is a fantastic stop for any visit!

This place is beautiful, and unique. I have never seen anything like it. However, I find it a bit odd to charge an entrance fee when people are literally just stopping by for 10/15 minutes. Especially when the weather is very windy and cold, people are not going to be here for long. I understand having to maintain the area but maybe a fee could be for parking and it could be a smaller price for a short time and increase with time, for those going for a longer visit. I do still recommend visiting as it is truly one of a kind.
