Alexandrovsk-Sakhalinsky is a port town on the northwest coast of Sakhalin, on the shores of the Tatar Strait. It is considered the oldest settlement on the island, but it most famous for once being the short-term home of Anton Chekhov, where he wrote The Sakhalin Island.
There are one daily bus between Tymovsk and Alexandrovsk (leaving 8 o'clock at the time of writing), connecting with the daily overnight train between Yuzhno-Sakhalinsk and Nogilki which arrives at 7.51, any of the other departures on the railway would require you to overnight in Tymovsk. In the opposite direction there is a daily bus from Alexandrovsk at 17, allowing you to return south with the Nogilki - Yuzno-Sakhalinsk train at 21.10. Remember to double check all this before heading out, since schedules change.
You may officially need a permit to enter the city, but the local government can't really seem to decide one way or the other, so check up on this in Yuzhno-Sakhalinsk before heading out.
The sightseeing capital of the Far East this is not, but there are a few things even beyond the requisite Chekhov Museum. Look for the Three Brothers (Три брата), a set of three monolithic rocks jutting out of the water just west of the town, as well as the port's lighthouse, which is a little farther out (3km outside of the town). If you are resourceful, you might also get a local to direct you to the network of tunnels dug by prisoners at the katorga—a major nineteenth century penal camp on the island.
