Donegal has many natural wonders. One of those wonders is a fairly rare and remote place that is known as the secret waterfall Donegal. This waterfall sits inside a sea cover. You’ll only see it at the proper tide. It’s missing from most tourist maps, but it’s getting more attention lately. Here is everything you need to know about it.

What Is The Secret Waterfall In Donegal?

The secret waterfall Donegal lies within a coastal cave. You can only see it at low tide. It’s one of Ireland’s most magical secret spots.

Local Name And Nicknames

Locals sometimes refer to it as the Largy Waterfall. Others deem it a hidden waterfall Donegal has kept secret for no one to see. It’s also not a typical waterfall, as it is inside a cliff cave.

Why Is It Considered Secret?

It is “secret” because it’s difficult to stumble upon. There are no signs pointing you to the location. Most travel apps don’t list it. So basically, you won’t find it unless the trip was planned and you set aside some time to get there.

Where Is The Secret Waterfall Located?

The secret waterfall is near the village of Largy, located between Killybegs and Ardara. It’s nestled inside a sea cave on the Wild Atlantic Way. You have to walk from the viewing point at Largy to catch a glimpse!

Map And Coordinates

The waterfall is located in between Killybegs and Carrick. Just underneath the Largy Viewpoint, which has a nice view of Donegal Bay, this is where the cliff path begins. The cliff path begins above a lay-by on the roadside.

Proximity To Local Towns

Ardara and Donegal Town offer some decent areas to base yourself. Parking in Donegal town is limited so arrive early if you plan to park. Otherwise, you can stay in Donegal Irlanda and make a full day trip.

How to get to the secret waterfall Donegal?

You can park at Largy Viewpoint on the road between Killybegs and Ardara then walk down the grassy slope towards the coast. Follow the coast at low tide to the cave. It has a waterfall behind it.

Reaching Largy Viewpoint

Start at the largy viewpoint. Park off the main road, as there is not a formal car park. It has just enough space for one or two vehicles. 

The Walk To The Trailhead

From the viewpoint, follow the narrow grassy path down towards the beach. The terrain is steep, rough and muddy in some places. Good footwear is essential. The walking path to the cave is not marked, so it is suggested to bring a map or saved GPS location.

Hiking Route And Safety Tips

The route is very steep, muddy and uneven. You have to wear proper gear. Only go at low tide, and find out tide times before you go. 

The Coastal Route

You will walk over a rocky shoreline. The ground is uneven, so you’ll need to be careful. The rocks may also be wet from sea spray. This is not a wheelchair-friendly path, and is not suitable for small children.

Tide Times Matter

You need to time your visit for low tide in order to avoid being stuck. You should check and take note of reliable sources of tide times Donegal, tide times Killybegs, or tide Killybegs beforehand. Tide data from nearby tides Buncrana may help, but it is better to stick to local readings.

What To Expect On The Way

The 15-minute walk involves climbing over boulders and slippery stones. Eventually there will be an opening to the cave. Inside you will witness a waterfall coming down from above, and you will hear it bouncing off the rocks in the cave, a magical experience.

What Makes The Waterfall Special?

It’s tucked away in a sea cave and only shows up at low tide. This makes it feel secret and rare. The echo of falling water in the cave is serene. Few places in Ireland feel this wild. 

Unique Geological Features

This waterfall is inside the sea cave that falls directly onto a rocky shoreline. If the sun is shining into the cave you may be lucky enough to catch a glimpse of a rainbow in the mist.

Best Time To Visit

Low tide is the only time to visit this waterfall safely. Use a Donegal tides app or check local surf and sea charts to access low tide times. 

You will have your best chance to both reach the cave, and leave for a safe return if you arrive within 30 minutes of low tide. Late spring and early autumn have the least vegetation in the caves.

Practical Information For The Visitors

There are no signs, toilets, or cafes in the area. So, bring your own snacks, water, and charged gadgets. Also use Google Maps for directions to find the locations.

Access Through Private land

The path to reach the waterfall may be on private farmland. Local farmers currently allow access. So, as a courtesy to these farmers, you are asked to treat their land with respect. Do not litter, close any gates after you, and be quiet if there are any animals in fields you are crossing. 

Local Etiquette

Please keep dogs on visible leads, avoid playing loud music, and remember that there are no bins, toilets, or shops anywhere close by. Take all your waste and rubbish with you when you leave.
