Longest multicache in the world?

[Guest broek]

I am in the act of creating a monstrous multi cache. It contains 12 caches and to find the final cache you should have driven over 200km. Is my cache the biggest around?

In terms of waypoints, your cache equals my Silicon Forest dodeca (12) waypoint cache

however, mine are all within a single Nature Preserve and can only be reached by foot (by design). Also, mine consists of only a single cache at the final waypoint.

 

As for number of actual caches and distance, I'd say your far and above any I'm aware of
