Eryri National Park’s majestic mountains, lush valleys, and crystal-clear lakes attract visitors from across the globe. Choosing the best time to visit Eryri depends on the type of visit you’d like. This guide explores the pros and cons of visiting Eryri in each season, helping you plan an unforgettable visit to the National Park.

Springtime marks a period of rejuvenation in Eryri as the landscape comes back to life after the autumn and winter months.

The season offers the perfect opportunity to explore the historical wonders of Eryri, including its magnificent castles or Yr Ysgwrn, the cherished home of one of Wales’ most celebrated poets, Hedd Wyn.

Spring also offers an ideal climate for engaging in recreational pursuits like canoeing or paddleboarding. With warmer temperatures and less crowded waters compared to the summer months, it’s a great time to immerse yourself in these outdoor activities.

Wild Swimming and Water Activities

While spring is the second busiest season in Eryri, the number of visitors during this time is only about half of what it is during the summer months. This makes spring an ideal time to visit Eryri if you’re looking for warmer weather without the crowds that come with summertime.

However, it’s worth keeping in mind that the easter and spring bank holidays tend to attract a surge of visitors as schools close and families take advantage of the pleasant weather.

If you can, visiting Eryri during the school term or on weekdays is a good option if you want to avoid the hustle and bustle that often accompanies the popular holiday periods.

As temperatures get warmer, you might enjoy exploring one of the many campsites and glamping sites in and around the National Park, but it’s best to keep in mind that rain is still likely during the spring.

You should book any accommodation in advance as the spring and summer seasons are the busiest times in Eryri.

However, you should note that the easter and spring bank holidays can get extremely busy throughout the National Park and the surrounding areas.

If you’re visiting with a canine companion, you should remind yourself that many farming activities such as the lambing season happen during the spring. You should always keep your dog under close control on public footpaths. If you’re close to livestock, you should keep your dog on a lead.

The summer is by far the busiest season in Eryri. It’s no surprise that the National Park sees such an increase in visitors during the summer months as schools close and the weather gets warmer.

During the summer, visitor numbers can double in Eryri compared to the spring. The key to visiting Eryri in the summer is to plan before your visit, book what you can in advance and be aware that it will be busy—especially in popular areas such as Yr Wyddfa, Llanberis, Ogwen and Betws y Coed.

If you’re considering visiting any attractions, it’s best to check their availability well in advance and book your place beforehand to avoid disappointment.
