The local shipping line Diskoline provides regular services from Ilulissat to Oqaatsut, and further to Sarqaq, in summer months.
You can also charter a boat from Ilulissat.
The most beautiful is, of course, to hike to Oqaatsut. It is a beautiful, pleasant, track, takes some 5-7 hours. You can not get lost, just follow the coast line.
Beautiful short and long hikes.
During the season, the kayakers come from Ilulissat for a 4-5 hours tour at the southern bay of Oqaatsut, beautiful experience to kayak between the icebergs. You can also join them directly in Oqaatsut.
There is a typical Greenlandic food store. At most times, it is well stocked.
Eat & Drink
All in all, the food in Rodebay is pretty bad, but they serve a rare Greenlandic microbrew there (you must have cash on hand to pay for the beer, oddly).
There is restaurant (H37), in a building of the earlier fish factory. It was run by a German couple, taken over by a nice Greenlandic couple in 2015. Excellent food.
There is a small, cozy hotel (Hotel Nordlys) with at least 4 rooms, clean, including breakfast, and a kind of a youth hostel, next to H37. I understand, there is even another bed & breakfast (as of 2017). The first and third can be booked through Booking.com.
Beware the mosquitoes if you're there in the summer. In early July, the mosquitoes are brutal — you will have to wear headnets 24/7 whenever you are outside.
In some years, there are no mosquitoes at all.
