Ascarium: Tricks & Treats 2026

Through October the aquarium becomes Ascarium, with a family Halloween trail of challenges winding between the displays. Visitors can meet the Sea Witch or Warlock, stop at themed photo spots, play visual games and collect a reward once the activity sheet is complete. The trail is included in standard admission, which starts at £16 per adult booked online in advance or £22 on the day, and under-2s go free. Entry is by timed slot, and booking two or more days ahead secures the best rate. The event page gives opening hours of 10am to 3pm, with last entry at 1.50pm.
