Devin Castle is the best place you can visit near Bratislava. This place is breathtakingly great. A beautiful castle, which you must visit while in Bratislava. To get here, you need to take bus No. 29, which stops right under the SNP bridge, on the boulevard. The bus ride takes about 20 minutes, but buy a return bus ticket, as there is no place to buy a ticket there. The entrance ticket is €5 per person (at least that's what I paid on the day of the museum), but I think the regular price is €8 per person. Here you can see remains of old buildings and churches that existed in this place in the past. When you enter the castle courtyard, there is a well where you need to throw water from a bucket. In front of the stairs to go up to the castle, there is a small cafeteria, with cheap and good drinks. There is not much to climb to the top and the climb is not difficult at all. When you climb to the top, there is a museum there, and from the museum you continue to a small cave and come out on the other side. There is a beautiful view from the terrace of the castle. From there you can see the confluence of the Morava and the Danube, the entire field, but also Austria. Right next to the castle is the state border line between Slovakia and Austria. It is not marked where Austria begins, but you can see that on Google Maps. The whole place is nicely decorated and is regularly cleaned and sanitized. The toilets are clean and tidy and there is no entrance fee. In the museum next to the toilet there are displays about World War II and the events that took place in this place at that time, and at the entrance you can buy souvenirs. Unfortunately, I didn't buy any, because the employee was on a break. From the bus station to the castle, it is about a 1km walk along an easy path.
