Snowdonia (Eryri), covering around 823 square miles, is the most iconic, scenic and largest national park in Wales. From the dramatic heights of Snowdon (Yr Wyddfa), the tallest mountain in England and Wales, to tranquil lakes, showy castles, golden beaches, and deep green valleys, Snowdonia is bursting with beauty, history, and adventure.
Whether you are here for a weekend escape or a full on getaway, Snowdonia offers something exciting and memorable for every kind of traveller including hikers, nature lovers, culture seekers, and daydreamers. To help you make the most of your visit, I have gathered 10 must see sights and must do experiences that truly capture the magic of this incredible place. Consider this your ultimate Snowdonia bucket list, because no trip here is complete without them.

- Snowdon (Yr Wyddfa)
- Castell Harlech
- Cader Idris
- Llyn Padarn
- Harlech Beach
- Zip World – Penrhyn Slate Quarry
- Llyn Tegid (Bala Lake)

- Swallow Falls
Hidden just outside Betws-y-Coed in Snowdonia National Park, Swallow Falls is an absolute showstopper – Wales’ tallest continuous waterfall and a true natural wonder that feels like stepping into a living postcard. Its thunderous roar and cascading waters have inspired poets, artists, and filmmakers alike, making it a timeless symbol of wild beauty.
For just a small entry fee of £2, you can get up close to this breathtaking spectacle, with viewing spots that let you feel the mist on your face and hear the waterfall’s powerful song. Parking nearby is limited but worth the early arrival to beat the crowds.
To truly experience Swallow Falls at its most dramatic and peaceful, plan your visit early in the morning, especially after rain when the falls are at their fullest and the crowds are thin. Afterwards, unwind with a stroll along the scenic trails winding through this enchanting landscape, the perfect way to soak up the magic and serenity of Snowdonia. This is not just a visit; it’s a chance to connect with nature’s raw power and beauty like never before.
- Snowdon (Yr Wyddfa)
Snowdon (Yr Wyddfa) is not just the highest peak in England and Wales (standing proud at 3,560 feet), it is a place that stirs something deep in your soul. Whether you are a seasoned hiker, a nature lover, or simply curious to experience the magic of the mountains, Snowdon is a must.
If you are up for an unforgettable adventure, I would highly recommend a sunrise walk. There is something truly magical about reaching the summit just as dawn breaks, watching the first golden light spill across the rugged peaks of Eryri (Snowdonia). The world feels still, quiet, and powerful. It is not an easy climb, but it is one you will remember for a lifetime.
There are six main paths to the summit, each with its own personality and challenges. Whether you are in it for the sweeping views, the solitude, or the sense of accomplishment, there is a route that will speak to you. The Llanberis Path is the most popular as it is the most gradual and offers plenty of space to take in the surroundings at your own pace.
And if hiking is not quite your thing, don’t worry, the Snowdon Mountain Railway is a fantastic way to experience the beauty without the climb. Departing from Llanberis, the charming train winds its way up the slopes, offering jaw dropping views right from your seat.
However you choose to reach the top, Snowdon is more than just a mountain, it is a journey, a challenge, and a moment of peace all in one.
- Castell Harlech
Perched high on a rocky crag with sweeping views over the sea and Snowdonia mountains, Harlech Castle is a place where you feel history under your feet. Built in the late 13th century by Edward I, it is one of the finest examples of medieval military architecture in Europe. The sheer scale is awe inspiring, from its perfectly designed concentric walls to the towering gatehouse and the ingenious sea staircase. If you are even slightly into castles, this place will capture your imagination instantly.
Harlech is not just about stone walls and battlements, it is about stories. This castle has survived centuries of siege and strife, from the Wars of the Roses to the English Civil War. It even inspired legends and songs, including the stirring “Men of Harlech.”
It is also a brilliant day out for families. The visitor centre is smartly laid out, and kids love running along the ramparts, peeking into towers, and picturing what life was like inside these ancient walls.
Whether you are a history buff, a photographer chasing epic views, or just someone who appreciates a place with a great story, Harlech Castle is worth the trip. It is not just a historic site, it is a time machine, set against one of the most beautiful backdrops in Wales.
- Cader Idris
Climbing Cader Idris mountain is one of those experiences that stays with you, not just because of the dramatic mountain views, but because of the stories, the solitude, and the quiet, wild beauty that surrounds you every step of the way.
This is not just any mountain, it is a mountain of myth. Legend has it that if you spend the night on its summit, you will wake up either a poet or a madman. It is named after Idris, a mythical Welsh giant who is said to have used the mountain as his throne. Honestly, when you are walking its ridges or looking down over the misty lakes below, it is easy to believe the magic.
The views from the top are nothing short of spectacular. You look out across glacial lakes, sweeping valleys, and on a clear day, all the way to the sea. One of the most breathtaking spots is Llyn Cau, nestled in a perfect bowl beneath towering cliffs. It is like something from a dream, especially at sunrise or sunset when the light turns the whole landscape gold and violet.
Whether you are heading up for an adventure, fitness, photography, or just to clear your head, Cader Idris gives you space to breathe. It is wild, rugged, and steeped in legend, and by the time you reach the top, you will not just feel accomplished, you will feel connected to something timeless.
- Llyn Padarn
Llyn Padarn is one of those rare glacial lakes where everything comes together: stunning scenery, rich Welsh heritage, and enduring adventure. The lake itself is crystal clear, serene, and beautifully reflective. It is perfect for a quiet moment by the water or capturing that postcard worthy shot of the famous “Lone Tree” standing elegantly on the shore. If you catch it at sunrise or sunset, the whole place glows.
If you are into water activities, Llyn Padarn is a dream. You can kayak, paddleboard, even take a refreshing swim and there is something magical about floating beneath the mountains of Snowdonia. Prefer to keep your feet dry? There are lovely walking and cycling paths that loop around the lake, with plenty of places to stop, breathe, and take it all in.
One of my favourite ways to enjoy the area is by hopping aboard the Llanberis Lake Railway, a charming little steam train that chugs along the lakeside. It is slow, scenic, and full of character, offering beautiful views without breaking a sweat.
Just a short walk from the lake is Llanberis, a welcoming village packed with history. Make sure to stop by the National Slate Museum, where you will step into the stories of the men who once worked the mighty Dinorwig Quarry, perched right above the lake. It is a powerful reminder of how deeply connected this landscape is to the people who lived and laboured here.
- Harlech Beach
If you have ever dreamed of a beach that offers both jaw dropping scenery and a sense of peace you can not quite find in busier coastal spots, let me introduce you to Harlech Beach. Nestled along the Welsh coast, this place quietly blends natural beauty, rich history, and a wonderfully laid back vibe. It is one of the most special places I have stumbled upon in Wales.
The first thing that strikes you is the space. Harlech Beach stretches out in wide, golden sands that seem to go on forever. Whether you are up for a long walk, a family beach day, or simply want to find a quiet spot to sit and listen to the waves, there is room for it all. With the rugged peaks of Snowdonia rising just inland, the views are nothing short of epic.
What really sets Harlech apart is the sense of history woven into the landscape. Just above the beach, perched dramatically on a rocky hill, is Harlech Castle. It is a UNESCO World Heritage Site, and walking its ancient walls feels like stepping back in time. Part of the Morfa Harlech National Nature Reserve, the area is also a haven for wildlife lovers and photographers, with dunes, rare plants, and migrating birds.
Even in summer, it is blissfully quiet. Easy parking and a gentle dune path make it accessible, and the nearby town offers charming cafes and shops to explore after the beach. If you are planning a Welsh road trip, do not miss this coastal gem. It is low key, beautiful, and unforgettable.
- Zip World – Penrhyn Slate Quarry
Imagine standing at the edge of a historic slate quarry, the wind in your hair, the vastness of Snowdonia unfolding before you. Now, imagine launching yourself into that vastness at over 100 mph. Welcome to Zip World Penrhyn Quarry, where adventure meets history in the heart of North Wales.
The main draw? Velocity2, the fastest zip line in the world. One moment you are standing at the edge of a vast, historic quarry, heart pounding. Next, you are soaring at over 100 mph, headfirst above a sparkling blue lake, with mountains on the horizon and the wind roaring past your ears. It is equal parts terrifying and exhilarating and you will want to do it again the moment you land.
There is more here than just speed. Whether you are racing friends on gravity fueled mountain karts, twisting through the air on a zip line rollercoaster, or taking a rugged off road tour through the slate quarry’s industrial past – there is a thrill for everyone. When it is time to slow down, you can refuel at the Blondin Restaurant with views that stretch for miles.
It is bold, wild, and absolutely unforgettable. If you are looking to shake up your weekend with something epic, Zip World Penrhyn Quarry is waiting. It is open Friday to Tuesday from 10 AM to 5 PM and closed on Wednesdays and Thursdays.
- Llyn Tegid (Bala Lake)
If you are dreaming of a peaceful escape where the mountains meet the water and life slows down just enough for you to catch your breath, Llyn Tegid (or Bala Lake) is calling. Tucked deep in the heart of Snowdonia National Park, this is Wales’ largest natural lake – a shimmering stretch of water more than 6 kilometers long, cradled by mountains and sky.
Whether you are gliding across the still surface in a kayak or paddleboard, catching the breeze in a sailboat, or just dipping your toes at the edge – Bala Lake is pure, water soaked freedom. Prefer something quieter? Cast a line for trout and perch and let the hours drift by (just do not forget your rod license).
For a touch of old world charm, climb aboard the Bala Lake Railway, a narrow gauge steam train that chugs beside the water with breathtaking views and stops like Llangower, where picnics and lakeside strolls feel like something from a postcard.
If it is wildlife you love, this place is alive with it. Over 70 bird species, the occasional otter, and deer that slip like shadows through the woods. Want to stretch your legs? Walk through the gentle Town, River & Lake Path – perfect for families and anyone who wants lakeside beauty without breaking a sweat.
- Llyn Idwal Circular
If you are craving a walk that is as soul stirring as it is accessible, let me introduce you to one of Snowdonia’s best-kept (yet wonderfully reachable) secrets: the Llyn Idwal Circular. This 3 mile trail begins at Ogwen Cottage and leads you around a glassy mountain lake cradled by dramatic peaks. It is like stepping into a postcard – mirror like reflections, moody skies, and total tranquility.
The route is not only adventurous enough with rocky paths, streams, and open views, but also gentle enough for families and dogs (on leads). Whether you are chasing golden hour photos or just a peaceful escape, this trail delivers.
If you are craving more? Tack on a climb to Devil’s Kitchen for some added drama. Short, stunning, and endlessly calming, Llyn Idwal is Snowdonia at its most magical. Bring boots, your camera, and someone you love walking with. You would not regret it.
By the time you leave Snowdonia, don’t be surprised if a part of you wants to stay. It is a breathtaking mix of rugged peaks, peaceful valleys, and rich heritage that stirs something deep within. Whether you are here for adventure, quiet moments, or a taste of Welsh culture, this stunning national park offers far more than just beautiful views. It is a place to explore, to breathe, and to reconnect. Once you have experienced its magic, you will find yourself longing to return.
