The Stolowe Mountains
This is something completely unique - there is no way to confuse these rocks with anything else in Poland. Mountain panoramas are great here (especially that one can usually admire them standing on the edge of vertical rock),but rock labirynths are even more impressive.
Similar showplaces one can find on Czech side of the border where monumental rock towns are located in Adrszpach and Teplice.
Additionally, in the heart of the Stolowe Mountains one can see interesting peat bogs (wet spongy grounds of decomposing vegetation). All this makes this area a "must-see" for every landscape photographer!
