Iceland Vacation Review: Diamond Beach, Jökulsárlón Glacier Lagoon, Dynjandi Waterfall, Höfn, Stuðlagil Canyon Hike, Boat Tour

The entire trip was great and memorable. That being said, here are some of our highlights:
Diamond Beach is amazing. Go to both sides of the river.
Zodiac boat tour on Jokulsarlon Glacier Lagoon. In addition, Fjallsarlon Lagoon in the early morning before the crowds arrived was beautiful.  
We really enjoyed a day and an overnight in the Westman Islands. Go to the Volcano Museum.
The many waterfalls were lovely. Dynjandi waterfall in the Westfjords gets a special shoutout.
Forest Lagoon and Sky Lagoon were both special relaxing spas we enjoyed.
The little town of Höfn was a nice surprise. We could see back across the peninsula to four glacial tongues coming off Vatnajokull.
One of our many dining highlights was the Tomato Farm. We added onto our reservation the greenhouse tour and the stable visit, both worth the extra cost. 
Stuðlagil Canyon (hike in on far side of the river instead of going to the overlook).
