Best Time to Visit Snowdonia


Snowdonia, a land of ever-changing seasons, offers a unique and diverse experience throughout the year. Ensure you’re well-prepared for the dynamic weather conditions.

Nestled amidst mountains and close to the sea, Snowdonia is known for its unpredictable weather, and in the higher elevations, snowfall is not uncommon. If you’re an outdoor enthusiast, it’s essential to consult experts before embarking on your adventure. The Llanberis Mountain Rescue website provides a comprehensive daily weather guide, including terms like ‘severe chill effect,’ ‘freezing above the summits,’ and the reassuring ‘no risk of blizzards.’ The Met Office, recommended by Snowdonia National Park officials, is another reliable resource.



Snowdonia comes alive in the summer, making it an outdoor activity hub. However, the resilient locals embrace the outdoors year-round, so don’t assume that Snowdonia hibernates in December and January; Snowdonians are a hardy bunch.

Winter hiking and climbing require specialized local guides or extensive experience, along with top-notch safety gear.

February, March, and April may bring rain and wild winds, but they also offer the charm of misty lakeside mornings or cozy moments with a bowl of cawl in a Conwy cafe.

May is a splendid time to experience spring in Snowdonia. Additionally, the Ffestiniog & Welsh Highland Railways host their annual beer festival in May, providing another reason to visit. During the summer, they run jazz trains; watch out for local announcements.

June brings warmer weather, ideal for fair-weather hikers. July and August are perfect for canoeing, camping, and foraging in the great outdoors.

School holidays can turn Snowdonia’s quaint towns into crowded chaos, particularly with charity climbers flocking to the Snowdon summit in the summer. Expect queues, commotion, and crowded cafes during this season.

One summer event worth waiting for is the Llangollen International Musical Eisteddfod, transforming the riverside town of Llangollen into a musical epicenter during the second week of July.

September in Snowdonia is simply sublime with fewer crowds, comfortable conditions, and the Helfa Gelf (arts trail) inviting you into local artists’ studios every weekend.

Gwledd Conwy (Conwy Feast) in late October is a celebration not only of Snowdonia’s produce but also of music and arts. Set in the medieval town on the outskirts of the National Park, it features live music, dancing, and delectable feasts.

Apart from the festivities, October in Snowdonia offers fiery autumn foliage, crackling log fires, and stargazing in the Snowdonia Dark Sky Reserve.

November grows darker, and December even more so. However, the lack of crowds and the presence of only locals in pubs and on the hills can provide a peaceful experience.


Claire Copeman, a representative from our Snowdonia multi-activity holiday provider, Adventure Tours UK, emphasizes that the national park is excellent for year-round hiking. However, winter hiking in the mountains demands specific skills and experience due to harsh conditions. Conversely, popular routes can get crowded during the summer months. For a more serene experience, consider less-traveled paths in summer or explore the iconic peaks in late spring or early autumn.


The Ffestiniog & Welsh Highland Railways are a must-visit, not just for the name but also for their dedication to the local railway scene year-round. In May, they host an annual Beer Festival, and during the summer, they feature Jazz Train events.
