What is recorded here

Polltoophil Main Sink opens near Castletown in County Galway, joining the regional cave list as a documented point rather than a advertised attraction. That distinction matters because the ground may hide depth, water or ownership, while the name alone gives no permission to enter. Treat the sink as a living boundary: read the land, respect the owner and leave the dark water untouched.
