Key Points

Be very careful at this site as it has claimed many divers. There is little in the way of emergency facilities and the depths can be very tempting for some.
BSAC do not support diving in this quarry
 

Dorothea Quarry

Nantle, nr Penygroes, Caernarfon, Wales


Overview

 

 

Introduction

A great place to dive with lots of interesting features. Sadly there are no facilities at all other than a rough track and some space to park. It does get very busy at the weekend.

There are two main access points to the lake, both can be a bit tricky when laden with kit etc.

I love this place!

 

 

How to get there

  1. Take the A4087 from the A55 and follow the road to Caernarfon.
  2. In Caernarfon follow signs for Porthmadog (A487)
  3. About a 2 miles from Caernarfon you will hit a roundabout. Turn left staying on the A487.
  4. Follow road into Penygroes
  5. In the village of Penygroes turn left along the B4418
  6. Follow road to end and turn right and follow road to Nantle.
  7. Shortly before Nantle you will see a large lake on your right, just passed this lake, on the left, is a row of houses, turn left along these and follow the track to the quarry. If you pass the red telephone box on your left you have gone too far. Backup about 100 yards.
