I'm so glad I found this excellent company to help me get out into the wilds of Nuuk (well, up a local hill in the ice, but it seemed wild enough to me!).
tl;dr - I throughly recommend the trip specifically and Two Ravens in general. Go with them, you'll have a great time.
Thorlak guided us at every stage in planning how to enjoy ourselves during our time in Nuuk. He gave us great communication, sound ideas for what would be available and he was perfectly open with us that we were travelling at a quiet time of year (early February) so would probably end up having to pay for a private tour for the two of us travellers - the website prices start with a minimum of three. We were fine with that, and it was good that it wasn't a last-minute shock that no one else would join.
There were plenty of options for fun - we chose the least-strenuous because we are two out-of-shape Brits nearing 50 years old and are both fairly inexperienced in the frozen wilderness. On the day Ella was our guide and we thoroughly enjoyed our time with her - she was knowledgable, patient, gently encouraging and great company for a few hours in the cold. And she brought jammy dodger biscuits, which is a plus in any situation. She also explained that Greenlanders don't take themselves too seriously, and like to laugh when people slip over. So we were only too pleased to keep her entertained...
The conditions seemed tricky to me - we walked in ice spikes rather than showshoes because of a lack of snow this year. But we got round safely and didn't break any bones, cameras or speed records.
Talking of cameras, it's one of the most picturesque places I've been to on earth, so make sure you pause, look up and appreciate it.
We had a great time with plenty of laughter. I even like that my legs still ache back in London four days later. It reminds me of a fantastic trip.
