>>2854908I go to Carpathians or Sudetes every year which is less often than to Cracow-Częstochowa Uplands cause the Uplands are just 30 minutes of driving away from me while the closest part of Carpathians is over 2 hours away. I would say that if you want a challenging hike, every part of Carpathians will be better than the Uplands but only Tatra Mountains which are the highest part of Carpathians is really challenging. In terms of views only Tatra is better than the Uplands because the Uplands have lots of cool rocks and castles. Same with rock climbing, most of Carpathians aren't very rocky and Tatra is the only part of it that rock climbers love more than than the Uplands. A small con of rock climbing in Tatra is that you need a climb registration in a shelter so they know where to find you if something goes wrong. Generally speaking Tatra is by far the coolest range in Poland but also the most crowded and nearby hotels are expensive.
There are also Sudetes by I don't wanna pretend to be a sudete expert cause I've never been to Śnieżnik Massif or Rudawy Janowickie which seem pretty cool but I've been to some parts of Sudetes and Table Mountains are likely the most beautiful mountains in Poland other than Tatra cause they have cooler rock formations than the Uplands.
Pic is photos I made in Carpathians this year. The top one is from Gorce Mountains (you can see Tatra far away) and the bottom one is from Tatra Mountains.
