Joanna & Fox Adventures - just book with them!  - Our tour guide was Joanna.
We can not recommend her and the company more highly.
They were completely aware of the popularity of all the spots we visited... read more and requested we meet early so that we could make an early start and see the spots with as little congestion as possible.
When at the different spots, Joanna was happy to take photos & recommended the best spots to stand for great photos.
She gave a great running commentary that was interesting and entertaining.
She warned us about the flies at the lake and offered head nets if wanted.
The weather was glorious and the day was a full 9hours with 2hours relaxing at the Natural Baths.
(Just as an aside, we needed to buy antihistamines and Joanna googled the nearest pharmacy that would still be open, she drove us there and back, with no expectations of payment.)
Joanna went above & beyond to ensure that this trip was the best it could be.
I have said very little about the places because they are beautiful and need nothing more added from me.

Great Akureyri area private tour  - My mother and I had a wonderful half day private tour with Baldur. He developed a great itinerary that included Godafoss Waterfall and Laufás Turf House Museum. Having grown... read more up in the area, he is very knowledgeable. He's also quite thoughtful about making his guests comfortable.

Falling in love with Iceland  - The tour was awe inspiring. Myself and my daughter were the only people booked that day so we got a solo tour. Baldur could not have been more helpful and... read more stopped lots of times in addition to those listed on the tour. We have fallen in love with northern Iceland and I heartily recommend Fox Adventures.
