Stopped here on my ride through the GAP. The hostel consists of one main sleeping area with perhaps 20 bunk beds and two private rooms with 3 bunks each. There's a cellar where you can park and wash your bike. Everything was very clean.
The town of Rockwood is very quiet, hardly saw anyone on the streets. Not much of a choice in bars or restaurants. The Old Mill
Negatives: The building is very close to the rail road tracks which run almost all night long. Hardly slept at all. The beds could also use blankets when nights get cool. All we got were sheets and pillow cases.
