Discover Anglesey’s Breathtaking Marine Life

Nestled off the northwest coast of Wales, Anglesey is a stunning island that captivates visitors with its natural beauty, charming villages, and spectacular coastlines. While Anglesey is renowned for its lush landscapes and historical landmarks, one of its most magical attractions lies just offshore: the opportunity to see dolphins in their natural habitat.

If you’re planning a visit to Anglesey, catching a glimpse of these majestic marine mammals should be at the top of your list. Whether you’re a nature enthusiast, a wildlife photographer, or simply looking for a unique adventure, this guide will tell you everything you need to know about where to see dolphins around Anglesey.


Why Anglesey Is a Dolphin Spotter’s Paradise

The waters surrounding Anglesey are teeming with marine life, from playful dolphins to curious grey seals and an array of seabirds. The island’s diverse and nutrient-rich waters provide the perfect environment for dolphins to thrive, making it a hotspot for marine wildlife enthusiasts.

Anglesey is fortunate to be home to two commonly spotted dolphin species:

  • Bottlenose Dolphins: Known for their playful and social behavior, bottlenose dolphins are a favorite among visitors. They often leap out of the water in acrobatic displays, creating unforgettable moments for onlookers.
  • Common Dolphins: These smaller dolphins are also frequent visitors to Anglesey’s waters, often seen in pods as they glide gracefully through the waves.

Top Locations to See Dolphins in Anglesey

To maximize your chances of seeing dolphins, timing and location are everything. Here are the best spots around Anglesey where sightings are most frequent:

1. Puffin Island (Ynys Seiriol)

One of the most renowned locations for dolphin spotting in Anglesey is Puffin Island, located near Beaumaris on the eastern tip of the island. While the island is famous for its seabirds—such as puffins and razorbills—it’s also a prime location for spotting dolphins and grey seals. The waters around Puffin Island are particularly rich in fish, attracting dolphins who come to feed and play.

  • How to Visit: The best way to explore Puffin Island is by taking a boat tour from Beaumaris. These guided tours not only increase your chances of spotting dolphins but also provide fascinating insights into the local wildlife.

2. Holyhead Bay

On the western side of Anglesey, Holyhead Bay is another hotspot for dolphin activity. Its sheltered waters provide an ideal hunting ground for dolphins, and it’s not uncommon to see pods swimming close to the coastline.

  • Pro Tip: Visit during calmer sea conditions for better visibility. Early mornings and evenings are often the best times for sightings.

3. South Stack Cliffs

While South Stack is better known for its dramatic cliffs and bustling seabird colonies, the waters below frequently attract dolphins. Visitors often spot them from the viewing platforms near the iconic South Stack Lighthouse.

  • What to Watch For: Keep an eye on the horizon for dorsal fins slicing through the water, especially during summer when dolphins are most active in the area.

4. Red Wharf Bay

For those seeking a quieter and more tranquil dolphin-spotting experience, Red Wharf Bay offers breathtaking views and a chance to see dolphins closer to shore. This bay is also a haven for seabirds, so don’t forget your binoculars.


When Is the Best Time to See Dolphins in Anglesey?

Dolphin sightings can occur year-round in Anglesey, but certain times of the year offer better opportunities:

  • Summer (May to September): The warmer months see an increase in dolphin activity due to the abundance of food in the waters around Anglesey.
  • Early Morning & Dusk: Dolphins are most active during these times, so plan your trips accordingly.
  • Calm Seas: Sightings are more frequent when the sea is calm, as dolphins tend to stay closer to the surface.

Spotting Other Marine Life Around Anglesey

While dolphins are the stars of the show, Anglesey’s waters are also home to an array of other fascinating marine creatures:

  • Grey Seals: These inquisitive animals are commonly seen basking on rocks around Puffin Island and South Stack. They’re often curious about boats and may pop their heads out of the water to say hello.
  • Seabirds: Anglesey is a birdwatcher’s paradise. Keep an eye out for puffins, guillemots, and even peregrine falcons along the cliffs.
  • Porpoises: Smaller and more elusive than dolphins, porpoises can also be spotted in Anglesey’s waters, particularly in deeper areas.

How to Maximize Your Dolphin-Spotting Experience

To make the most of your dolphin-spotting adventure in Anglesey, consider these tips:

  1. Take a Boat Tour: Joining a guided boat trip significantly increases your chances of spotting dolphins. The local skippers are experts at finding the best locations and can often predict where dolphins will appear.
  2. Bring Binoculars: While dolphins often come close to shore, binoculars can enhance your viewing experience, especially from cliffside locations.
  3. Be Patient: Wildlife sightings are never guaranteed, so be prepared to wait and enjoy the beautiful scenery in the meantime.
