Hobart sightseeing tours and hop-on hop-off bus tours often make a stop in Queens Domain, where the hilltop parks afford views along the waterfront. The Royal Tasmanian Botanical Gardens are the headline act, with over 35 acres (14 hectares) of Asian and European-themed gardens, lily ponds, and conservatories, filled with rare and exotic plants and flowers. Additional highlights include the grand Government House, the Soldiers Memorial at Legacy Park, and the Tasman Bridge, which runs all the way over the Derwent River and is open to walkers and cyclists, as well as cars.
