Although Rysy is the highest peak in Poland, it's relatively easy to climb it to the top. The hike is quite tiring and steep; nevertheless, it's nowhere near as difficult as some other trails in the Tatras - like, for example, the trail to Zawrat via Dolina Gasienicowa which is my favorite in the whole Tatars.
As an interesting fact, I can mention that the Rysy peak is also a border crossing point - you can easily go down to the other side which is in Slovakia. The Slovakian side of Rysy is easier but less spectacular. As both countries lie within the Schengen zone, of course, there are no guards or barricades; you won’t even notice you’re in a different country.
