Llyn Maelog: A Wildlife and Outdoor Activities Hotspot

Llyn Maelog

Maelog Lake (or Llyn Maelog as it’s more commonly referred to) is situated on the east side of the popular seaside village of Rhosneigr. It’s a lake that’s bursting with wildlife and fascinating plant life, plus it makes an excellent location for a range of outdoor activities such as walking, fishing, or paddleboarding.

So, why is it worth paying a visit to this Site of Special Scientific Interest (SSSI)?

Llyn Maelog: A Village Green with a Difference

That’s right, the lake actually boasts officially designated “Village Green” status (bestowed by the Llanfaelog community council), despite its aquatic nature. In fact, it’s the only lake in Wales with this official designation.

But the real attraction to Llyn Maelog is the flora and fauna this aquatic haven supports. From rare birds to several different types of fish and plants, this small corner of Anglesey plays host to all kinds of flora and fauna, making it well worth a visit.

So what might you expect to see when paying a quick visit to this enchanting location?

Llyn Maelog Wildlife and Plant Life

The lake supports a broad spectrum of birdlife. Depending on what time of year you visit, you could be treated to sightings of coots, pochards, and the occasional golden plovers. Then there are more traditional birds such as greylag geese and oystercatchers that frequent these waters. You might also spot a grey heron or two on your way around the public footpath that lines the shore.

The real jewel in the crown is the reed warblers that come to the lake during the summer months. You might well hear them before you see them, with their famous birdsong emanating from the reedbeds near the lakeshore during bird breeding season.

Under the water’s surface, the Llyn Maelog is also teeming with life. With water depths of three to ten feet, there’s plenty of room for the fish species found here, which include pike, bream, roach, rudd and perch.

Concerning the plant life at the lake, Llyn Maelog boasts eight separate species of pondweed, including the horned, perfoliate, blunt-leaved and lesser varieties. There are also plenty of reed varieties that hug the shall water margins close to the lakeshore.

Outdoor Activities at Maelog Lake

With so much wildlife and plant life to contend with, it’s no surprise that there are plenty of outdoor activities to partake in at Llyn Maelog.

Fishing at Llyn Maelog

With all the fish mentioned above, it’ll come as no surprise that Llyn Maelog is a fantastic dead bait and lure fishing location. The largest recorded Pike caught here was a 25lb 2oz fish, so it’s undoubtedly well worth visiting. If you do intend to gear up and head out to this lake, please note that fishing is limited to the right-hand (Eastern) bank only.

Birdwatching at Llyn Maelog

With so many birds in and around the lake throughout the year, it’s no wonder that this spot is so popular with keen twitchers. It’s worth visiting during the winter and again during the spring/summer to experience the full range of birdlife Maelog Lake has to offer. There are plenty of benches, seats, and picnic tables to spend a few hours watching the birds.

Paddleboarding at Llyn Maelog

This lake can be an excellent place to blow up your paddleboard and take it for a paddle during the spring and summer months. While it’s certainly not the biggest lake on the Isle of Anglesey, the often still waters and lack of rocks make this a perfect place to hone your skills before taking your kit down to the nearby beaches at Rhosneigr.

Walking Around Llyn Maelog

One of the best ways to enjoy everything Llyn Maelog has to offer is by strolling around the lake on the public footpath that hugs the shoreline. It shouldn’t take much longer than half an hour to complete a full lap of the lake, and you can follow the route map below if you want a longer walk that also takes in some of the Rhosneigr Beaches.

Llyn Maelog dogs
Ensure to keep your dog at arms length from the water, as it often contains toxic blue-green algae

Also note: Llyn Maelog is known to harbour toxic blue-green algae, which can kill dogs within minutes if exposed. Unfortunately, a local dog owner tragically lost both of their young dogs after they swam in the water of Lake Maelog a few years ago, and many others have required vet treatments to survive since. You cannot spot toxic blue-green algae as it’s invisible to the naked eye unless found in blooms. It is best to exercise caution and not let your furry friends in the water.

Getting to Llyn Maelog
