Shelling Tips and Best Practices

The best time for shelling is during low tide, especially after a storm. Early morning or late afternoon shelling can yield the best finds.

Bring a mesh bag or bucket for collecting shells, and don’t forget sunscreen, water, and a hat. A small shovel or scoop can be handy for digging up buried treasures.

Only collect empty shells to ensure that you’re not disturbing live creatures. The Ten Thousand Islands is a delicate ecosystem, and it’s essential to practice ethical shelling.
