It's our 21st Festival!
This year, we are continuing in the same vein as last year so the cost of admission will be the same price as admission on regular (non-festival) days. We are also opening 10am - 5.30pm on Friday. You can book individual sessions or weekend registration as follows:
INDIVIDUAL SESSIONS: Go to the regular admissions booking page to purchase day time sessions (available at a later date) or for Stargazing Evenings (Friday and Saturday Evenings) book here Stargazing.
WEEKEND REGISTRATION: Weekend registration can be purchased using the book online button at the top of this page. Please note the following:
- Weekend registration entitles you to admission from 2.30pm on Friday afternoon until 5pm on Sunday afternoon (when The Centre is open). NOT valid before 2.30pm on Friday.
- Please note: when you make the booking you can only select 29 August from the calendar and it will say 2.30pm to 5.00pm but it does mean 2.30pm on Friday to 5pm on Sunday). This means you will have 3 hours extra in The Centre before we close from 5.30pm - 6.30pm to re-set for the evening session.
- If you purchase weekend registration you will receive a wristband to wear throughout the weekend which you must show when you go through reception.
- If you want to come in before 2.30pm then you can purchase separate tickets for session 1 as above (individual sessions instructions).
- Weekend registration DOES NOT include lecture tickets, camping or planetarium tickets.
CAMPING: You can purchase camping either with or without purchasing weekend registration using the book online button at the top of this page. Purchasing camping does not entitle you to admission into The Centre. You will need to either purchase weekend registration or admission to individual sessions as above.
