Greenland is incredibly beautiful, and we had so many unforgettable experiences: kayaking between icebergs through the fjords, being cozy in our sleeping bags at night while hearing the glacier nearby breaking apart, and hiking through stunning scenery. Our guides Pablo and Iñigo were both very knowledgeable and fun to hang out with, and the other travelers on our trip were lovely!
A couple things to note: the Challenging rating of this trip is real. We kayaked up to 5-6hrs/day with minimal breaks, and it's definitely quite hard even if you're in good shape. Personally I was looking for a challenge, and was happy with this.
It would have also been nice to know that flights between Iceland and Greenland can often have serious delays/cancellations. Our flight there was delayed by 24hrs, and we fortunately didn't have delays getting home, but it's worth considering to save 1-2 days buffer at the end of your trip in case you get stuck in Greenland.
I only rate 4 instead of 5 because the pacing of the trip could use improvement -- the first couple days felt very rushed, while the last 24-36hrs had no official plans. Overall, highly recommend this trip!
