A one-of-a-kind guided treasure hunt awaits you at the Seaquarium this Halloween!
This year, scientists from the past are back… Rising from the grave, they are surprised to discover that nothing has changed since the 1930s, despite their warnings.
They entrust you with one final mission: armed with a map, set off in search of clues and take on the challenges created by the scientific outreach team at Seaquarium Institut Marin.
A fun and educational adventure to enjoy with the whole family, filled with puzzles, challenges and discoveries!
