I know this is an ancient thread but I just came back from a week in Iceland with a day trip to Greenland. It was one of the high points of my trip. When I booked it there was very little information other than on the site where I booked it (IcelandAir Connect) so I wasn't sure what to expect. I'm hoping that anyone who does a search on "Greenland" in this thread will find this.

The flight left from RKV, not KEF- a big plus. I'd rented an Airbnb place in the western part of Reykjavik and when we landed after the trip, I walked it and was back in my apartment 35 minutes later. We flew to Kulusuk- same latitude, on the east coast of Greenland, an 80-minute flight. We crossed two time zones! Our guide met our group at the airport. Kulusuk is actually an island- a village of 240 people who mainly make a living as subsistence hunters. We walked into town after first viewing it from an amazing scenic overlook and walking down a small glacier, and visited the small church, a grocery store and a small museum. We were given the option of going back to the airport by water in one of the boats owned by residents for another $40- it supplemented their income and gave us another view of a beautiful area. They went very slowly so we had a chance to take in the scenery. I also got some great shots from the plane coming in and going out.

Obviously you can't get a full picture of the country and its culture in a portion of a day in a small fishing village but it's always enlightening to put yourself in another corner of the world. I met a group at RKV headed out for a 5-day kayak tour off a larger ship; you can also book a 5-day "Highlights of Greenland" tour form the IcelandAir connect site. Kulusuk has a hotel and a hostel.

Highly recommended with two caveats: there's a lot of walking over rocks, but no great altitude gain. Still, you need to be agile. Second- bring your own food. The grocery store was really meant for the residents and didn't have a lot of ready-to-eat food. I made a picnic out of a can of tuna with a pull tab (no can opener needed) and a loaf of bread (took the leftover bread back with me). I was starved at that point (despite having a couple of Costco protein bars with me) and it was delicious! Available food at the airports was limited to empty calories- mostly salty snacks and candy- and no food was served on the flight. There was a food stand at Kulusuk Airport but it wasn't open when I arrived.

I hope this post will encourage others to make the trip.
