Downpatrick Head, North Mayo








To be completed by me...


Downpatrick Head situated just outside the nearby village of Ballycastle is one of the finer dives sites carved out by the atlantic.   Looking out to sea, Doonbristy sea stack rises up from the ocean, holding strong in in front of Downpatrick head.  It's spectacular formation promises exceptional diving. 

Launching in Bunatrhir Bay, known locally as Ballycastle pier, the Downpatrick head and the sea stack are about 30mins drive by rib.


In 2012, Julia O'Rourke organised her AD dive trip here for an extra long May Bank Holiday weekend.


The boats were launched and retrieved from the slip located in Bunatrahir Bay, know locally as Ballycastle pier.  It is located just over 1km from the house in the direction of Ballycastle village.  Follow the sign posts for the Stella Maris Country House Hotel.  The slip is located 50m beyond the hotel where the road terminates. The slip launches you into Bunatrahair Bay where chart datum in the bay is 5m.  The bay faces directly North.  It is difficult to launch/retrieve boats from here with northerly winds as the bay is exposed.  The dive sites are about 20-30mins drive by rib from the slip.

The slip is mainly used by one fisherman who has a mooring in the bay.  There are many fishing nets in the bay and it is easy to catch one of them so it is important to be vigilant.  Scuba divers are know to frequent this pier.  Boats can be launched in the bay at any time.  We were there on a high spring weekend and had to walk the boats into the slip at low tide but were still able to retrieve from the water as conditions were calm.   There is ample space for neat parking of 6-8 cars. 


General site info

Site 1: Downpatrick Head

Start at the beginning of the third finger, which is a good sheltered place for kitting up. Dive down the wall where you will find many openings in the cliff and kelp down to 15m with some very large rocks.

At the bottom, depth 28m, go along the wall in a Southerly direction and you will come to an amphitheatre. It is very hard to describe it's beautiful smooth rock, it is as if someone designed it! As you exit keep your left which will bring you along another ridge. This is a suitable dive for advanced novices.

Site 2: Downpatrick Head

This dive is on the inner side of Downpatrick Head. Start on the second finger and again go in a SW direction to a maximum depth of 30m. Descending down the wall you will see the ridge go to the right, this will lead you to a very large opening which will bring you into the cliff under the headland. Coming back out, keep a straight course and your dive will finish at the Northern tip of the Head.

Site 3: Doonbristy Sea Stack

to be updated!

Site 4: Ceide Fields

The pyramid for the interpretive centre is a good navigation marker to find this site.  The steep cliffs rise 60m straight out of the water, they are 300-400m long and surround the site.  The cliff walls drop vertically to a sandy bottom at 20-25m. This cliff is composed of deep horizontal cracks, it has abundant plant and fish life. As you head out to sea the bottom is covered with large rocks. There are many sea caves opening in the cliff walls.  Visibility here is generally good.

Safety/VHF/Coast Guard

Traffic reports are to be made to Glen Head coastguard on channel 24.  It is right across Donegal Bay and has clear line of sight form Downpatrick Head dive location.  If communications are not going through on ch.24 then contact Donegal Bay coastguard on  ch.02  or Belmullet on ch.83 although due to the location of the broadcasting mast from the Downpatrick head dive site the signal might not be good.

The nearest local sub aqua club is Grainne Uaile SAC. A C.M.A.S. dive club. 

There is a local rescue diver, Kevin Gilvary based in the town of Killala. He is very knowledgable on the North Mayo dive sites.  He owns a pub, Gilvary's (no sign over the door) situated directly across the road from the petrol station on the Ballycastle side of Killala.


In 2012, we stayed in a beautiful house perched high and looking out over the atlantic and Doonbristy sea stack.  The house called "Muingelly" is located a little over 1 km from Ballycastle pier.  It is a privately owned detatched residence which sleeps 12.  Is is wonderfully spacious and the accommodation comprises of 4 spacious double rooms, a master bedroom with a walk through closet and a twin room.  The living area boasts fantastic views of the sea stack.  There is a large stove fire that can be lit and the owner left a few bags of turf for us.  The house owner's parents live nearby and the key can be collected from them.  There is ample space for parking boat trailers, cars and setting up compressors,  a large detatched shed can be used for storage too. 

Contact the owner: John Madden through the website for booking the house. Electricity was charged extra at a rate of 20euros for the weekend.  Gas (for heating) was calculated at .85c/litre


We mostly made our own entertainment in the house.   Ballycastle village has up to 14 pubs.  Polkes local emporium and pub where time truly stands still was our favourite for the weekend.

If blown out, there are some fantastic walks (parts of the western way) and historical sites (megalithic and neolithic) to visit in the area.  You are free to ramble the bogs, hillsides, stone ruins along the coastline.  The Ceide Fields and walks along Downpatrick head or Killala beach are recommended.
