Update in May 2014: In case you came across with "No Admittance" signs, try approaching the mid-point from South East...and perhaps in the evening or during weekend...
Two bridges connect the island to mainland in Herttoniemi and Tammisalo. Buses 84-89 operate from Herttoniemi underground station to Laajasalo.
The place is partly suburban, but large areas are still open for outdoor activities such as geocaching.
Previously only one cache has been placed to Laajasalo: Stargher IV
Historical manor houses Degerö, Stansvik and Jollas are located on the island.
At starting point you'll find some written instructions, but after that it's a game of colours, numbers and your wits. You don't need a calculator, though.
Cache should be winter-proof, but heavy drifting of snow may play some tricks at starting point. Some digging will help.
Please hide all boxes very carefully
Don't sign any cache notes nor look for hints from those. They are there only for occasional geomuggles. The final cache contains a small blue logbook.
This is rather long walk, but I hope you'll enjoy it.
