We’re excited to welcome you to Svalbard! A land of Arctic landscapes, unique wildlife, and unforgettable natural phenomena. Located at 78° North, Longyearbyen offers a truly extraordinary setting for our Interop week.
This guide covers everything you need to know before traveling.
To reach Longyearbyen (LYR), you must transit through mainland Norway.
Most routes connect via:
Flights to Svalbard are limited and weather-dependent. Delays between mainland Norway and LYR are not uncommon, so we strongly recommend building in sufficient buffer time when booking international connections.
Svalbard is visa-free, but you must be legally permitted to enter mainland Norway, as all routes transit through it. If you require a Schengen visa, ensure it covers your transit accordingly. You are personally responsible for ensuring compliance with Norwegian entry regulations.

Airport shuttle vouchers from LYR will be provided. Please submit your confirmed flight details via the form circulated by the organizers so transfers can be coordinated.
Interop Dates: April 27 – May 1, 2026
The default accommodation dates are:
If you requested early/late accommodation in the RSVP form, your booking may instead be April 25 check-in and/or May 3 check-out. Please refer to your individual confirmation email for your exact dates.
⚠️ Stays before April 25 or after May 3 are at your own expense. If you wish to extend your stay at your assigned hotel, the organizers can help you book additional nights so you do not need to transfer.
All meetings and work sessions will take place at Funken Lodge, with workspace access available 24/7 (including for participants staying at Radisson).
Daily standup begins at 9:00 AM (Monday–Friday).
⚠️ Anything not listed above is not covered and will need to be paid personally.
We’ll be in Svalbard during Sunny Winter / Midnight Sun season (late April), when 24-hour daylight begins and snow still dominates the landscape. Temperatures typically range from around -15 °C to -5 °C, with windy and changeable conditions.

Layering is key in Arctic conditions.
Essentials
Recommended
Polar bears can be present outside the Longyearbyen settlement area, and encounters can be dangerous.
Do not leave the settlement without a licensed guide. This is not optional, it’s a safety requirement on Svalbard, and applies to any walks/hikes outside town.
Always follow local safety signage and instructions from guides and hotel staff.
Emergency number in Svalbard: 112
