There are also dives daily from the shore
at the Churchill Barriers on Blockships sunk to protect the British
Naval Fleet anchored in Scapa Flow during WWI & WWII.
These
wrecks are spectacular lying in 12m of water, or less and within easy
swimming distance from the shore. This dive site is ideal for certified
divers who have not dived for a while, or who are not qualified for the
deeper dives in Scapa Flow.
Whether you choose guided dives in Scapa Flow or
the shallower blockship wrecks you should ensure that your
guide
will be an Instructor or Divemaster who is familiar with both the
history and layout of the wrecks and experienced in the diving
conditions of the area. Guided dives are typically run for both
individuals and small groups and are available to everyone. |
