Welcome to Cork’s Bull Rock: Home To ‘the Gateway to the Underworld’

Welcome to Cork’s Bull Rock: Home To ‘the Gateway to the Underworld’

There’s a little island (Bull Rock) off the coast of Cork that looks like a set from a Pirates of the Caribbean movie…

To be completely honest: I’d never heard about Bull Rock up until last year. I was sat in a cafe in a little town called Castletown-Bearhaven on the Beara Peninsula in Cork. 

It was the tail-end of summer… and it was lashing down outside. The original plan for the day was to join an organised walking tour, but the guide rang that morning to say that it was cancelled.

When the chap in the cafe dropped down my coffee, we got to chatting about the area and what there was to do that was a little off the beaten path.

That’s when he mentioned what he described as ‘the most unusual of the many things to do in Cork‘. He was, of course, talking about Bull Rock.

Some quick need-to-knows about Bull Rock in Cork

Although Bull Rock is one of the more off-the-beaten-path places to visit in West Cork, a visit here is pretty straightforward.

Below, you’ll find info on its location, how to get to Bull Rock and what there is to see and do nearby.

1. Location

The chances are you’ll have heard of Cork’s Dursey Island (yep, it’s the one that’s accessible via a cable car).

Dursey is situated at the southwestern tip of the beautiful Beara Peninsula and it’s off the western point of Dursey that you’ll find Bull Rock Island.

2. How to get there

There are two different Bull Rock tour providers: Dursey Boat Trips and Skellig Coast Discovery. You’ll find info on both below, from where they leave from to how much the tours cost.

3. What to see

Now, although you can’t get onto the island itself, you’ll get to have a spin around it on the different tours and you’ll also go through the hole in the centre. You’ll also see Bull Rock Lighthouse and discover the story behind the mysterious little island. 

About Cork’s Bull Rock: ‘The Entrance to the Underworld’

You’ll find Bull Rock Island off the southwestern tip of the beautiful Beara Peninsula in the even more beautiful region of West Cork.

Off the western point of Dursey lies three rocks (one of which looks like a set whipped straight from a Pirates of the Caribbean movie):

  • Bull Rock
  • Cow Rock
  • Calf Rock

Like something from another world

I’ve done a fair whack of travelling around Ireland over the past 10 years, but I’ve never seen anything like this place.

From the moment that I first laid eyes on Bull Rock, I thought that it looked like a deserted island that you’d find tucked away somewhere in the Indian Ocean.

The type of place that pirates would have used back in the day to stash their swag.

What you’ll see if you visit Bull Island in Cork

If you take one of the Bull Rock Tours (info on these in a minute), you’ll be treated to a very unique experience.

The island, which is roughly 93m high and 228m by 164m wide, is arguably one of the more overlooked places to visit on the Wild Atlantic Way, and a visit here packs a punch. Here’s what to expect.

The passageway through the rock

As you can see from the photos above and below, there’s a narrow passageway that cuts through the island.

You’ll see this referred to as ‘the Entrance to the Underworld’ on social media and on places like Reddit and Tripadvisor.

I’ve done a bit of digging, but I can’t find any more info on the background to the name. It’s not hard to see where the name came from, though – take a look at it up close and you’ll see why!

On the Bull Rock Tours, you’re take through the dark tunnel that runs beneath the island, right the way through to the other-side. 

The Bull Rock Lighthouse

The original Bull Rock Lighthouse was built by Henry Grissell of Regent’s Canal Iron Works in London, after he won the contract in 1861.

He completed construction of the lighthouse in 1864. However, just 17 years later, in 1881, the Islands’ lighthouse was destroyed by a storm.

Thankfully, the lighthouse keepers weren’t in the tower at the time. It wasn’t until 1888 that a new lighthouse was completed and it wasn’t until 1st of January, 1889, that the light on the island started up again.

Bull Rock Lighthouse operated successfully for many years after. The, in early 1991, it was fully automated and the Keepers were withdrawn.

Very interesting indeed. I’m curious to know if the ‘buildings’ below the lighthouse were occupied - maybe the men who worked in the lighthouse? Just wondering ☘️
