When to go
- September to March gives long, dark nights; in June the sky never gets fully dark across much of the UK.
- Go near the new moon: see our moon calendar.
- Time a visit for a meteor shower, such as the Perseids in August or Geminids in December.
What to bring
- Warm layers, a hat and a flask: it is colder than you think on open ground.
- A red torch to keep your night vision.
- Binoculars: 10×50s show the Moon's craters and Jupiter's moons.
- A sky map app set to red night mode.
Be a good visitor
Park only in proper car parks, keep to paths, close gates and take your litter home. Many sites are working farmland or nature reserves.
