Vişeu de Sus
Vişeu de Sus 
The only logging train hauled by narrow gauge steam engines (760 mm) still in use in Europe, crosses the Maramureş Mountains in the middle of one of the most wild and beautiful Romania's landscapes, and the only means of transportation in the valley. Built between 1930-1932 for transporting wood, the train is still used for the original purpose, attracting thousands of tourists from all over the world. The journey is long and with several fuelling stops. The train can also fall off the rails, but at the slow speed of 10 km/hour that poses no danger. The passengers (who are experienced in the matter) can help get the train back on the rails using anything they can lay their hands on: cut pieces of wood, chains, axes, or hooks.
The main line is 43 km long (Viseu de Sus-Comanu), with other two branches (Novat Valley-13 km long, and towards Stevioara-3 km), and usually takes (just until Paltin, the main station, situated at 21 km from Viseu), between 2 and 3 hours. A journey with the Mocanita is like going back in time: on the valley is not cell phone signal (there are working only radio stations), there are no shops, and provisions of food and other consumables have to be made before departure. However, when the train arrives at Paltin station, you have the opportunity to buy food and drinks from the train. Also there is no certainty about the departure and return hours, but it is usually around 15:00 at Viseu de Sus.
The ticket office opens at 07:00 and trains depart at 09:00. On Saturdays there can be up to three trains heading to Paltin, while on Sunday only one train may depart. Just find a train waiting on the tracks and hop on. Get there before 08:30 to obtain a good seat on the train if you're with a group. Tickets costs 48 lei (2013) per person. A BBQ lunch (11-21 lei) along with beer (6 lei) and other drinks can be purchased at Paltin.
At Paltin, you can continue hiking along the tracks further into the forest to Faina (old wooden church) and beyond. Be careful as the tracks are still in use by the local lumberjacks on diesel trains. If you decide to camp up there check with the office for the dates of returning trains.
There are numerous pensiunea in the area. If you cannot find a place, ask a local for 'cazare' (accommodation) and they'll direct you to one.
You can sleep in a train! Single 75 Ron with breakfast. 
At Paltin station, there is a short signed road in the woods, look out for it. It goes up to a sightseeing point next to the tracks. However, you should hurry a bit since the train stays at Paltin only for approx. 1,5 hour, and it definitely goes back without you.
