On Saturday, Reston’s Lake Fairfax Park will turn into a harbor full of pirates and privateers at the park’s inaugural Pirate Fest.

The events run from 10 a.m. to 6 p.m. Tickets are $10 in advance; $12 at the door; and $6 for Water Mine season ticket holder.

Here is what the Fairfax County Park Authority has in store:

A  Children’s Deck with pirate-themed moonbounces, puppet shows, stories and craft activities.

Pirates who will share stories about life on the high seas and lead pirate boat tours on the lake and lead singing of sea chanteys and tavern tunes.

A Pirate costume contest for kids.

A treasure hunt where participants will use their maps to find the spot marked by X.
