This secret Ontario island is filled with turquoise water and it's a magical place to swim

This island in Ontario may be small, but it has no shortage of magic. If you're looking for a last-minute summer adventure, this dreamy destination is worth a road trip.

The island is tucked away in an Ontario provincial park and it features glassy, turquoise water that will have you feeling like you've taken a trip to the tropics.

It's known for its unique, basin-like shape that creates an idyllic swimming hole.

The shores surrounding the island offer soft-sand beaches where you can relax and soak up some sun.

Here's what to know about this hidden gem destination.

Bathtub Island is a natural wonder located in Lake Superior Provincial Park near Katherine Cove.

When the crystal waves become high enough, the hollowed-out centre of the island fills with water, forming a natural "bathtub."

It's a magical place to relax and float.

In order to get to the island, you can follow the Coastal Trail from Katherine Cove for about half a kilometre. Once you reach the sandy shoreline, you can walk through the shallow waters to Bathtub Island.

The island consists of smooth rock, but it can be slippery, so it's best to use caution while exploring this natural wonder.

Parking is available at the Katherine Cove and Sand River parking lots. In order to visit Bathtub Island, you'll need to purchase a day use permit, which are available at the Agawa Bay Visitor Centre, Gatehouse and Park Office for $15.50.
