Dorothea, located in Gwynedd, North Wales is
an inland quarry and is one of the most beautiful quarries. Contrary
to the other inland dive sites in the UK this one has to be dived
with caution. The maximum depth is 120 metres max (394 feet) so
obviously it's not for novices due to the extreme depths in some
parts of the quarry.
The visibility is usually good and the water
cold in general but quite clear. There are no facilities on site
and this is not an official dive site although advanced divers
usually venture here looking for a challenge. You will see lots
of vans and cars tunnels and garden gnomes and a crane that was
used formerly in the quarry works.
At the tip of the Lyen Peninsula is Bardsey Island
which provides some of the most outstanding diving in Nortern
Wales. The dives here are recommended for advanced divers as the
tides can get very strong. Diving should be conducted at neap
low water slack.
Wreck lovers can dive the many wrecks on Bardsey.
One popular wreck is the Ilesha whose lenght is about 32 metres
Half Tide Rock in Pwllheli is the ideal place
if you want to dive around seals. There's plenty of fish life
around here including lobster and crabs. A little
further from these rocks you can dive on some wrecks
that are well broken up.
The Menai Straits has some exciting drift diving.
This dive is usually done by entering at Menai Bridge at slack
water and then swimming mid way through the channel. When the
current eases off submerge and drift for about half a mile (0.8
km) past the Swellie Rock then come back with
the flood tide. You should resurface near your entry point. Be
sure to use a conpass on this one to make sure you're satying
on the northern side during the return.
