Victoria is small and easily explored. A walk around Downtown, starting with the museums and architectural sights of the Inner Harbour, followed by a stroll up Government Street to the historic areas of Chinatown and Old Town, covers most of the key attractions, though seeing every little interesting thing along the way could easily take two days. Passenger ferries dart across the Inner and Upper harbors to Point Ellice House and Fisherman's Wharf, while more attractions, including Craigdarroch Castle and the Art Gallery of Greater Victoria, lie about a mile east of Downtown in the residential areas of Rockland and Oak Bay. Most visitors also make time for the Butchart Gardens, a stunning exhibition garden 20 minutes by car north on the Saanich Peninsula. Free time is also well spent strolling or biking through Beacon Hill Park and along the Dallas Road waterfront, heading out to such less-visited sights as Hatley Castle and Fort Rodd Hill, or checking out any of the area's beaches, wilderness parks, or wineries.
