Seeing the Sights

Starting in one corner of this grid and ending in another is a path revealing five famous spots in Boston.

The path goes from square to square up, down, left, and right, but never diagonally. No square is used more than once.

However, the path steers around 12 scattered squares whose letters do not belong to the famous sites.

These 12 letters, taken in order from left to right and top to bottom, spell a phrase descriptive of the tourist’s path. – By Emily Cox and Henry Rathvon
