Greenland is a wonderful country for hiking! But it depends on what types of scenery you enjoy as to where you should plan to go.

South Greenland (Narsarsuaq, Narsaq, Qaqortoq etc) is a very easy place to hike. There are no polar bears and there are established trails.

Sisimiut is another fabulous place to hike with established trails (as well as plenty of back-country to explore for yourself) . It forms one end of the famous Arctic Circle Trail if you are into long-distance hiking. There is also the possibility of kayaking in traditional Greenlandic kayaks there.

Elsewhere ... it depends heavily on your backcountry experience.

East Greenland is truly spectacular but there are no trails and the real threat of encountering a polar bear. Guided hiking/kayaking is the name of the game there.

Ditto the Tasermiut Fjord in South Greenland.

So really - it depends on what you want to experience and what kind of hikers you are. More info needed to be able to advise better.

I have a lot of hiking posts from Greenland on my blog in case you would like to read about soem of the options (East Greenland, South Greenland, Sisimiut)

I have to admit that I'm still a bit torn between the two but ColOmbia appears to have more to do which kinda suits. Good question mstep. I'm not much of a beach dweller. I nearly did a two week survival course in Guyana last year so spending time in the Jungle certainly appeals. Not a massive walker but don't mind trekking. Colonial villages would be cool to see but archeological sites tend to be more like gap fillers unless they're like massive temples etc. I like big cities but may be wise for me to explore Bogota for just a few days at the end of my trip so I'm near the airport?

I was in Greenland in July last year and some days it was warm enough for shorts and t-shirt'
But once the wind got up it was really cold.

EVERYTHING, except fish is imported.

Plane trips are expensive because Air Greenland only has a few planes.
I got stranded when the plane from Ilulissat to Kangerlussuaq was cancelled because the plane broke down. This meant I missed the flight from Kangerlussuaq to Denmark that afternoon.
The plane back to Denmark the next day was fully booked so they flew me to Nuuk for the night. The next day to Reykjavik in Iceland and the third day to Denmark. There are no direct planes from Nuuk to Denmark.
I got two free nights accommodation.
While I missed my flight back to Australia and had to pay to change the booking, I didnt mind as I got to have a few hours to walk around Reykjavik and Nuuk which was not on my itinerary.

There was a sign on the door of the breakfast room in Reykjavik hotel saying the police would be called if guests tried to take food out of the breakfast room. Ha ha.

Cologne is ok for overnight / 24 hours for me, but personally prefer Dūsseldorf and (somewhat smaller)Aachen. If you are in to 19th century industrial history, places around eg. Essen and Oberhausen have a lot to offer - enough for 2 or 3 days. Just bear in mind too that by late October the weather can get grey and drizzly so I wouldn't plan too much out doors.

All really good comments above!

I would double down on the tyre size, get the widest, most durable touring tyres your bike can fit...even if it means removing the fenders. Schwalbe being the crowd favourite.
Well built wheels of at least 32 hole spoke count, 36 is better.
Tubus racks are great.
A comfortable, very well broken in saddle!
Good money I spent on the stuff that keeps you comfortable and on the road. I wider tyre run at lower pressure will be more comfortable for long days in the saddle, especially in tough riding conditions. Being comfortable for long periods of time is crucial.....you don’t want to be sore and tired for days and days on end, throw in camping situations and things begin to get untidy quickly!

There’s a good reason that most of the long distance tourers you meet on the road have similar / the same gear. It’s proven and works well!! I’m sure you’ll find all this gear / brands as you sift through the mountain of online info available!

You’re focus for the bike needs to be on comfort and durability, along with ease of fixing or finding replacement parts in all locations. Weight, fashion and boutique / cool / exotic brands should be put to the side immediately.

I would leave your home town with ALL YOUR GEAR very well broken in and the best possible set up you can achieve. Don’t set off with thoughts of getting used to a situation that is not ideal.....you need to be comfortable riding a fully loaded bike for 6-10 hours a day....day in & day out.....along with nights of camping in less than ideal situations. Even though you are well traveled, this takes a while to get used to! Living on and from a Bike is great, but takes some time to fine tune and get used to.....start refining this process now!

Use the gear / clothes that you plan to tour with in all your training rides and shorter trips.....ALL YOUR KIT should be well broken in and nothing you use when you set off should be being used for the first time.....even down to the socks you wear, helmet, sunglasses etc etc...your practise rides or over night trips to test out your systems and processes will enable you to refine all of this down to the exact style, order etc that you like and prefer! If something isn’t quite right or it frustrates you, find a way to make it work....these little things that annoy you now will become worse after months on the road.
As above, leave home with the best possible set up you can achieve.......don’t plan on getting new, wider tyres, or anything else apart from standard spare parts, somewhere else along your route!
I’ve been looking for a spare tyre since I left LA in Oct.....now in Medellin, Colombia and no such luck :(

Preventataive Maintenance:- Swap out your chain every 5000kms, at the same time swap your tyres over front to rear....the rear will wear out quicker.....especially if you load up the rear wheel with only 2 Panniers......which I suggest you don’t.
Look after your drive train with regular cleaning and good lube! Especially in dry, dusty conditions. Sitting down with a toothbrush or something similar and brushing everything down with hot soapy water, rinse clean and wipe dry etc will see you good. This only takes 10-15 mins and will prolong the life of your gear! I’ve been using Squirt Brand chain lube on this tour and it’s the best I’ve ever used.....highly recommend!
Once a week it remove my tyres from the rim, turn inside out, put on my head torch and thoroughly go over the tyre looking for all sorts of road debris in the rubber.... I remove this with tweezers or nail scissors. Very rarely do you ride over something and puncture with Touring Tyres.....usually your tyre will collect something and after thousands of revolutions will work itself through the rubber and puncture the inner tube!
Get used to checking over your bike from time to time looking for anything out of order. Check bolts / screws etc and tighten where necessary. Maybe also have your bike put in the store for a good service after a few months on the road??

Your smart phone is your friend!! I attach mine to my stem with a Quadlock system and use for navigation!
Off line mapping Apps are brilliant and very accurate!
I use:- MapsMe, Mapy.Cz, OsmAnd, Overlander. They all have their pros and cons.....download for free from App Store, download the maps you need when online and away you go! I would start using them now and get used to their features and settings. Mapy.cz is my favourite right now!
Weather Apps are also brilliant and very accurate! Windy & Yr are the 2 that I use daily!! Windy has amazing features that you can customise nicely!

Others recommend reading journals from Crazy Guy......I disagree. There are now WhatsApp bike touring groups that you can join with 234 active members on them. I used the one for Asia a while back and now on the South American group! You post a question and within hours you have loads of replies from other bike tourers who are either there on the road right now or were there a few days ago. You get up to date info from other tourers on all required info like border crossings, where to stay, bike shops, spare parts, camping sites etc etc.
It’s brilliant and works very well. The problem is getting in to the group. The Asian one is always full and very popular. You’ll need to get the invite link from another Tourer who is in the group and keep trying until they accept you....ie, someone leaves and you can take their place! When you meet others on the road, ask them if they have the link, or lots of people on Insta / FB groups etc.....both an excellent source of current up to date info on bike touring!

Hope that helps?
Please don’t hesitate to fire back with some more questions.....there’s a great community on this board with years of touring knowledge.
