Preface
The idea for this cache was simple. This is the type of cache I would like to hunt for when I'm travelling. Tourist friendly, within walking distance of the terminal and with some sort of puzzle to play with as a preparation for the trip. A geochecker for verifying the solution and a decent size cache for trading geocoins. A peaceful hunting zone would be good, as there is typically no chance of coming back to the cache site another time. So, here you go. Feel free to copy the ideas to your home airport 
Welcome to Helsinki-Vantaa airport
If you have some extra time and want to get fresh air, here are some suggestions:
- Solve this mystery and go for cache hunting
- If mysteries are not your cup of tea, visit nearby T2 and trade trackables
- Bonus: Visit plane spotting and viewing terrace just for fresh air with a breath of kerosene (see waypoints for details)
Cache site
The cache site is located at approximately 15-30 minutes walk from the terminal entrance. Snowy conditions will increase the terrain rating by one star. Sneakers and snow is a bad combination.
You can start your journey from the trail head listed in the waypoints. Follow the shared pedestrian and bicycle road. Use Open Street Map and Karttapaikka topographic map to guide you to the second waypoint, which is located 100 meters east from the cache.
Mystery
The cache location can be solved from this cache description and this log entry.
You should verify your solution with the geochecker for an interesting piece of information.
