This is THE ECHO and it's a cache in the NXT LVL SERIES.
Welcome to the entrance. Go down and search for a sign with coordinates to find the cache.
You need a little bit of courage to do this, but don't be scared, nothing can hurt a geocacher!
- Former military district of the Swedish Armed Forces.
Have fun with the Echo, be kind to the nature and don't forget to leave it better than you found it.
