The Ultimate Guide to Summer in North Wales: Beaches, Castles, Lakes and Hidden Gems

North Wales is one of those places that feels tailor-made for summer. Long coastal days, mountain air, historic towns and wide open landscapes all combine to create the kind of destination that works whether you’re planning a weekend break or a longer escape.

From the rugged peaks of Eryri to the sandy shores of Anglesey and the charm of the Llŷn Peninsula, this region offers an incredible variety of places to explore. You can start your day walking beside a mountain lake, spend the afternoon on the beach, and finish with dinner in a historic town.

This guide brings together some of the best places to visit across North Wales in summer, along with practical tips to help you make the most of your trip.

Caernarfon Castle and the Waterfront

If you’re looking for a place that captures the spirit of North Wales, Caernarfon is the perfect starting point. Dominated by the imposing Caernarfon Castle, this historic town blends medieval architecture with a lively, modern atmosphere.

The castle itself is one of the most impressive in the UK, with polygonal towers, sweeping walls and incredible views across the Menai Strait. It’s a UNESCO World Heritage Site and a must-visit for anyone interested in Welsh history.

Beyond the castle, the town opens up into a network of narrow streets, independent shops and harbourfront walks. The waterfront is especially enjoyable in summer, with views across to Anglesey and plenty of spots to sit and take it all in.

If you’re planning to explore this part of North Wales in more depth, staying centrally can make all the difference. The Black Boy Inn in Caernarfon offers a characterful base within the town walls, making it easy to explore both the town itself and the wider region.

 

Beddgelert: A Storybook Village in the Heart of Eryri

Set within the mountains of Eryri (Snowdonia), Beddgelert is widely regarded as one of the most picturesque villages in North Wales. Surrounded by woodland, rivers and peaks, it offers a slower, more peaceful pace that’s perfect for a summer day out.

The village is steeped in legend, most famously the story of Gelert, the faithful hound. Whether or not you know the tale, the setting itself is enough to draw you in — with stone bridges, flowing rivers and scenic walking routes in every direction.

It’s an ideal place for a gentle walk, a relaxed lunch, or simply sitting by the river and enjoying the surroundings. From here, you can also venture further into the national park if you’re looking for more adventurous routes.

Aber Falls: A Scenic Walk with a Reward

For those who want a walk that delivers big scenery without requiring a full mountain hike, Aber Falls is an excellent choice. Located near Abergwyngregyn, the route follows a wide, accessible path through a valley before reaching the waterfall itself.

In summer, the landscape comes alive with greenery and wildflowers, while the sound of the falls grows louder as you approach. The final view — water cascading down from the Carneddau mountains — makes the walk more than worthwhile.

It’s suitable for families, couples and casual walkers, and offers a great introduction to the natural beauty of the region.

 

Rhosneigr: Relaxed Coastal Living on Anglesey

On the western side of Anglesey, Rhosneigr is a favourite for those looking to enjoy the coast without the crowds of larger seaside towns. Known for its laid-back atmosphere, it’s a brilliant place to spend a summer day by the sea.

The beaches here are wide and open, with plenty of space to walk, relax or take part in watersports. You’ll often see paddleboarders, windsurfers and swimmers making the most of the conditions.

Even if you’re not heading into the water, the coastal paths and open views make it a great place to explore. On a clear day, the sunsets can be particularly memorable.

 

Criccieth: Coastal Charm with a Historic Backdrop

Located on the edge of the Llŷn Peninsula, Criccieth combines seaside charm with a strong sense of history. The town’s castle sits proudly above the coastline, offering panoramic views across Cardigan Bay.

Below, you’ll find a traditional promenade, beaches and a selection of cafés and local spots to enjoy a relaxed afternoon. It’s the kind of place where you can take things at your own pace — whether that’s exploring the castle, walking along the shore, or enjoying a classic seaside meal.

Criccieth also works well as part of a wider coastal route, linking easily with Porthmadog, Abersoch and other destinations along the peninsula.

Llyn Padarn: Lakeside Views and Mountain Backdrops

Llyn Padarn, near Llanberis, is one of the most scenic lakes in North Wales. Framed by mountains and surrounded by walking routes, it offers a peaceful setting that contrasts beautifully with the busier peaks nearby.

In summer, it’s a great place for paddleboarding, kayaking or simply relaxing by the water. The lake’s clear views and open space make it ideal for both active visitors and those looking to unwind.

The nearby village of Llanberis also provides access to attractions such as the National Slate Museum and routes towards Yr Wyddfa, making it a great hub for a full day of exploring.
