I am looking for an excellent tour that enables us to see the tomato farm and offers Geothermal bread making at Laugarvatn Fontana. recommendations?
I am not familiar with any tours that combine those two. Usually, if a golden circle tour incorporates a hot spring, they do the Blue Lagoon or Secret Lagoon. You might check with tour companies and look into a private tour for this.
I used "Bus Travel Iceland" for my Golden Circle tour. We visited the Tomato Farm and had lunch. Very delicious. Went out and saw the Icelandic horses, and the tour included the Secret Lagoon at the end.
I didn't find any that offered bread making.
This was a small tour in a mini van, so tops was 16px, but we were only 5px.
