Plan your visit
As restrictions in England ease, we want to ensure that all our visitors, staff and volunteers still feel safe and comfortable when exploring our sites.
Many of our COVID-19 safety measures will remain in place, including enhanced cleaning, safe distancing and ticketed entry. We highly recommend wearing a face covering at all indoor venues and enclosed spaces.
We hope you will support us in these measures.
You must have a timed entry ticket to visit the Observatory, even if you're a Member. We recommend booking online in advance to avoid disappointment.
To make the most of your day out, buy a Royal Museums Greenwich Day Pass and get access to both the Royal Observatory and historic ship Cutty Sark.
Please note that Planetarium show tickets are not included in entry to the Royal Observatory and must be booked separately.
Shows run Friday-Monday during term time and daily during school holidays. For a full schedule and how to book, click here.
Located in the Astronomy Centre at the Royal Observatory, the Astronomy Café & Terrace is open at weekends and school holidays to Planetarium ticket holders. You can also pick up refreshments from stalls just outside the main entrance to the Observatory, or head towards the Parkside Café just down the hill at the National Maritime Museum.
Find the perfect museum gift, from books and prints to models, toys and games. Visit us next to the Meridian Courtyard, in the
Astronomy Centre, or shop online.
Find out useful information about facilities at our museums including cloakrooms, baby change and accessibility, and information for visitors with disabilities coming to any of our sites.
