The swan boats are a seasonal treat in Boston's Public Garden. Drivers pedal you (and other passengers) around the lagoon for 12-15 minutes.

Afterwards you can relax on the Common and/or visit the Tadpole playground.

Downtown parking can be tricky. If you want to drive, the Boston Common Garage costs $28 for 10 hours or $24 for 3. Uber can be a great option if you prefer to be chauffeured. And the MBTA can be the least expensive depending on where you are traveling from. Use their price estimators to determine the best option for you.
