A sheep at the summit
Snowdonia (Eryri) National Park isn’t like American parks which have set opening hours or require a pass to enter. Access is free and it’s open all year round, 24/7.
There’s no need to book to walk on Snowdon (Yr Wyddfa) or anywhere else in the National Park. The paths on Snowdon are Rights of Way, which means that they are open 24/7, day and night.
In fact, in the summer Snowdon is very much a 24-hour mountain; on top of the usual daytime walkers there will be people going up in the evening to see the sunset, going up at night to see the sunrise, and returning in the early hours of the morning.
Races on the mountain can include any of the six main paths, and do. These too might include overnight running. Note that no paths are closed, even if there is a race on, which is actually fairly frequently in the summer. This includes the International Snowdon Race up and down the Llanberis Path in mid-July.
However, sometimes weather conditions on the mountain can be such that going up is not advised (e.g. strong winds, torrential rain, lightning, snow and ice), though nobody will actually stop you.
Note:
- Hafod Eryri, the summit building, is only open in high season (see the link for exact dates).
- If you’re coming in a car, you’ll need to find a car park.
- If you’re new to mountain walking, you should read this page for first-timers.
- If you’re bringing a large group you should read this.
