This is really quite an interesting site because of its good state of preservation - you can easily imagine yourself being a millworker (or owner) in the early 19th century. The museum/visitor centre is a bit on the touristy side (telling the sad story of poor Annie McLeod who had to work in the cotton mills at an early age), but all buildings are well-preserved, including the schoolhouse and the residence of founder Robert Owen. You learn a lot about his ideas of utopian socialism, worker welfare, and urban planning (including his attempts to recreate a similar site in New Harmony, Indiana). The cotton mills were powered by the River Clyde which runs through the village, and you can walk upstream through a nature reserve to the famous Falls of Clyde. New Lanark is quite easily reachable by bus from the larger town of Lanark, which has direct rail connections to Glasgow.
