Snail trails 15 🐌 Creepy Mystery Cache

Welcome to the Snail Trails, GEO-ART in the area of Sabile and Abava valley! Why snail? Because Sabile has vineyard that is full of winesnails, also known as escargots. On top of that, winesnail is depicted in the coat of arms of Abava parish. And snail just looks good on the map! 🐌

Take your time, no rush, and enjoy geocaching!
