← Dive-sites: Bryn Hall Quarry

Description

Bryn Hall Quarry is a small but deep quarry with extremely difficult access. Other than the very steep and high quarry walls there is, to my knowledge, no other way to enter the quarry. If this is the case, it seems as though climbing equipment would be necessary.

There are many reports of diving here in the past and reports about depth vary from 20m to 55m. Personally, I have not been able to find out much about this quarry. Two divers have lost their lives in the quarry and diving is not advised (if even still possible).

The water is allegedly extremely cold year-round with poor vis near the bottom and high risk of entanglement due to large amounts of dumped barbed wire and military equipment.

  1. I have dived this quarry several times in the late 1960s, with the Liverpool University Sub Aqua club. It isn’t a particularly exciting dive in itself, apart from the quantities of unexploded ammunition at various places. We would dive to about 100 feet – without reaching the bottom, as far as I remember. My first dive there was slightly nerve-wracking – I was a bit heavy in the water, and descended to a ledge where I could see quite a few live (presumably) shells. I gingerly poked my fingers into the the spaces between the shells to keep myself from landing on them. Access wasn’t too bad – I don’t remember us finding it difficult, though a little strenuous.

    • Thanks for the info Stephen, very interesting to hear about dives to Bryn Hall as it doesn’t seem like anyone dives it at all these days. From looking around myself I havent found any ways in but there are private gardens most of the way round which I didn’t want to cross. Do you remember how you got in?
