There are three places where you swim underwater, except that one is a glitch and the other one fairly limited
Time-Tangled Island
In 1805 AD, Sacagawea is helping Meriwether Lewis and William Clark cross the Northwest. Go right until you enter the water. You can submerge your character's head below the water.
Big Nate Island
Get the photo blowing around the lighthouse, and swap it for Scuba gear at the Say Cheese photo shop. Now you can dive for Cap'n Salty's lost lobster trap. If you swim out to the right first, you can avoid trouble from rising bubbles. When your oxygen runs out, you must surface.
Mythology Island
In the underwater maze of Poseidon's realm, you can swim easily because passing bubbles replenish your air. If you stop at the right spot, you will receive new bubbles continuously and never run out of air.
