3 Reasons Why Autumn is the Best Time of Year to Visit Eryri National Park

Published on 10 Nov 2026 by Amy Greenwood

The beauty of Eryri National Park is that it can be enjoyed year-round, with every season providing something special. From nearby seaside strolls in the summer to snowy mountain hikes in the winter, the landscape shines in every season, but we feel Autumn might just be the best. 

Here at Dioni we have a number of idyllic cottages nestled in the heart of Eryri National Park that are perfect for an Autumn getaway, with real fires, hot tubs and plenty cosy charm.

Here are the best reasons to visit Eryri in Autumn.

1. Autumn Colour

Eryri National Park is home to many of the UK’s most ancient and beautiful woodlands. From the Atlantic Oak woodlands of Coed Felinrhyd and Meirionydd, to the popular forest parks of Gwydir, and Coed Y Brenin. Many of these amazing woodlands have plenty of family friendly walks, and with the Autumn colour, likely peaking in mid November this year, there’s no better place to immerse yourself in the beautiful colours of Autumn.

We recently published a blog post all about Forest Walks in North Wales so be sure to check it out for some inspiration.

2. Quieter 

Eryri National Park is one of the most popular national parks in the UK with 4 million visitors per year, mostly between April and September. It’s beauty and it’s variety when it comes to outdoor pursuits is an obvious draw for many, and if you want to tick off the hotspots such as climbing Yr Wyddfa, Tryfan, or The Glyderau, the Spring/Summer months can be incredibly congested. Parking can be tricky, you’re often battling the crowds to find your own slice of solitude, whereas from October onwards, everything becomes a little quieter and a little more peaceful. This time of year is a real sweet spot, the temperatures are still fairly mild so spending time in the outdoors is quiet comfortable, and weather-wise, the snow and ice of winter is still at couple of months away. 

If you want to experience Eryri and its wild beauty, if you’re looking for a peaceful stay in nature, then now is the best time.

3. Perfect Outdoor Weather

We all love a warm summer’s day, but I think we can all agree that the summer we’ve just had was maybe a little too warm. Whilst that’s great if you’re near the sea or a lake, somewhere you can have a quick dip or enjoy some water sports, however, if you want to do any sort of hiking, especially up some hills, then the heat can be pretty gruelling. 

For anyone who enjoys spending time in the mountains, or if you’re interested in hiking one of Eryri’s multi-day hiking trails such as The Snowdonia Slate Trail, then the cooler climate of Autumn makes for idea walking conditions. Of course, you’ll want to pack some waterproofs, and prepare for some inclement weather just in case, but there are still plenty of opportunities for nice sunny Autumn days without the relentless heat. Plus, the scenery looks much nicer in the Autumn as the sea of endless green fades into differing shades of yellow, oranges and browns.
