Two Quick Days in Sydney, Australia

There is more to Sydney, Australia than the Opera House. This articles gives suggestions for covering the city area in two days. From the aquarium, to the harbor cruise, and then on to the Blue Mountains, you will enjoy a scenic variety in two days.

Check out the Sydney Aquarium in Darling Harbor. It does not look big from the boardwalk, but it is built back from the harbor and has a large seal exhibit, penguin area, and an impressive shark tank. It is disconcerting to walk through the hallway and have sharks swimming over you, around you, and beside you. You are in their world and thinking the line from the movie Jaws, "We're going to need a bigger boat." Moving on from the shark area, the Great Barrier Reef exhibit fills the eyes with colorful fish. And in the crocodile area, you enjoy a laugh from atop the protected overhang. The sign reads, "If the fall doesn't kill you, the crocodile will." As if on cue, the crocodile opens its mouth wide and gives you a toothy smile.

After your aquarium adventure, stroll on to the pier and hitch a ride on one of the cruise catamarans. Generally, the shorter cruise offers a brunch and a ride through Circular Quay, past the Opera House, Harbor Bridge, and on into the main harbor. Spectacular homes dot the shoreline, as you bob past the Australian Navy port, the Royal Botanic Gardens, and various islands in the harbor. You get the feel of the city and how large it seems with all of the shoreline.

Once you land back at the pier, make your way to the "Rocks" historical area, and climb aboard a bus for an inland tour. The bus goes by sandstone buildings, churches, fountains, and always gives a breathtaking view of the harbor. Lovely parks dot the city and Australians, who love the outdoors, are taking advantage of the beauty of Sydney. Out to King's Cross and over to Bondi Beach, the bus stops to let you dash over to the white sand and COLD water. No wonder all of the bikini-clad women and muscled young men are lolling on the beach, not frolicking in the water.

The bus tour concludes a well- rounded introduction to Sydney. Now, you are prepared for a wider outreach the next day. In the meantime, Darling Harbor offers plenty of dining choices, both inside and outdoor patio seating. Enjoy an evening of good food and plenty of people watching.

Day Two in the Sydney area and it is time to head to the Blue Mountains. The two-hour bus ride quickly gets you out of town and into the rolling greenish/bluish mountains. A pit stop in the town of Leura allows you to stretch your legs and get a spot of tea. You head on to Katoomba for the Scenic Railway Ride. This is the world's steepest section of train. It was used for the coal miners in the area.

Walking around the park, you enjoy enchanting vistas of canyons, mountains, gum tree forests, and the blue haze given off by the eucalyptus oil. Other scenic points include Bells Line Road, Govett's Leap, and the Three Sisters rock formation. Gorgeous views and interesting folklore tales make this a worthwhile trip.
