Consider each blob of land. Each bridge is connected to two blobs of land (that's how bridges work). Each blob of land happens to have an odd number of bridges attached. Now, let's consider what a valid walk would look like. As you go on your walk, you record in a notepad each time you are in a certain blob of land.In this puzzle, there are exactly 2 islands with an odd number of bridges, so it is solvable since any case with 0 or 2 sections with odd numbers of bridges is solvable.
