No, Victor Harbor isn't a spelling mistake - or at least not one within recent memory. It is an error in the early surveying of the town that has persisted to this day

Victor Harbor is tourist oriented, and has many accommodation options, and some purpose built visitor activities. It draws a weekend crowd from Adelaide, and some visitors from further afield. It does cater for the schoolies after exams finish for the year so take this into account when selecting a time to visit.
Most people get to Victor Harbor by a 90 minute or so drive from Adelaide, but there is a coach service run by Premier Stateliner from Adelaide Central Bus Station and Goolwa. Fares are $19.50/$9.50. You can switch to a airport bus at Marion Shopping Centre rather than in Adelaide City, but check the timetable as buses to Marion only go every hour or so.
The Steamranger runs the Southern Encounter  service on Sundays twice monthly(Departing from Mt Barker in the Adelaide Hills), giving around 4 hours to explore the town. Adults $48.00. Children 5 years and over $26.00. They also run a train to Goolwa Sundays, Wednesdays and every day during the school holidays. One way fares are available on request.

Nearby Inman Valley is on the Inman Valey Rd, about 14km inland of Victor Harbor. The town itself has a couple of houses and a farm equipment shop, but Selwyn's Rock, more commonly known as Glacier Rock is near here. Access is by a very short walk with steps.
Waitpinga Hill is a lookout over the town and the water, above Encounter Bay.
Granite Island is undoubtedly the major attraction of the town. It is linked by a wooden causeway to the mainland. You can walk across the causeway in 15 minutes or so, or you can take a horse-drawn tram across. It is free to walk, but you have to pay for the tram.
Once you get to the island there is a walk that circles the island, and takes around 45 minutes. There are wildflowers, rock formations, and sea cliff views to see. There is a cafe/kiosk there too.
If you get the tram, it takes you further than just across the causeway. It travels around 200m on the island, as far as the cafe and visitor's centre complex - so it actually does save you a substantial walk - although it doesn't really save you any time.
