• Book a time slot online, since each trail caps entries per hour and the ticket desk only sells what's left; in the summer holidays, walk-up tickets between 10am and 3pm can run out
• Two separate trailheads: Szczeliniec Wielki starts in Karłów, while Błędne Skały has its own access road and an upper car park with timed entry, so doing both means driving between them
• Stairs and narrow gaps throughout, so leave the stroller in the car (neither trail works for wheelchairs) and bring a carrier for babies

Two rock labyrinths on the sandstone plateau of the Table Mountains (Góry Stołowe), the flat-topped range by the Czech border. Szczeliniec Wielki climbs about 680 stone steps from Karłów to viewing terraces, the 919 m summit and Piekiełko, the deepest crevice open to visitors.

Błędne Skały is an hour-long boardwalk route through a maze of towering rocks, with passages that narrow to a squeeze in places.
