Over 150,000 people are expected to pack the Town of Oyster Bay for seafood tasting, shucking competitions, craft vendors and live music.

Here's everything you need to know before you go.

For over 40 years, Long Islanders and visitors from across the country have packed the event. A fall celebration of one of the region's most iconic mollusks. This is the 42nd annual event.

The event routinely draws crowds of 150,000 to the town for the weekend.

Eat oysters, of course!

The event also boasts oyster shucking contests, an arts and crafts pavilion, amusement park, beer garden, craft vendors, food trucks and live music.

The event runs Saturday, Oct. 18 and Sunday, Oct. 19 from 11 a.m. - 6 p.m.
