Hi Cruise Guy, While in Isafjordur we went to Dyanjdi Waterfalls, a 7 seven layer waterfall that you can walk up to the top. It was beautiful. We had a private driver for 4 and the excursion was 6 hours. This was booked thru Iceland Backcountry and we paid per couple 2021 $376.
In Akureyri we were on an overnight so we went to Forest Lagoon on the day we docked, next day we did the diamond circle excursion thru the cruise ship since we had OBC. This took us to the Godafoss falls and to the Botanical Gardens. It was a 6 hr excursion, on a group bus tour. We could of used more time at both locations, especially at the gargens, it was beautiful. Had we known we could have done the gardens on our own the day before because it is located behind the church. So walkable from the port. Hope this helps. Djupivogur was not one of the ports we stopped at. We were on the Azamara Pursuit, loved the service and food, long port stops and overnights with this cruise.
