Dundas is home to the Dundas Valley School of Art. Marion Farnan and Emily Dutton established it in 1964, and it became a non-profit corporation three years later. Since 1970, it has been located in the former Canada Screw Works building from the 1860s. It began a full-time diploma programme with McMaster University in 1998.
The Carnegie Gallery is housed in the 1910 Carnegie library building and celebrated its 25th anniversary in 2005. It is run by the Dundas Art & Craft Association and hosts art exhibitions, book readings, concerts and a gift shop.
Dundas has many waterfalls within its region. The two most common visited waterfalls are Webster's Falls (named after Joseph Webster) and Tew's Falls. Both waterfalls are accessible by the Bruce trail leading to the Dundas Peninsula.
In 1819, Joseph Webster purchased property on the escarpment above Dundas, including the waterfall which still bears his family's name. In 1856, his son built a huge stone flour mill just above the falls but it was destroyed by fire in 1898. After the fire one of the first hydro-electric generators in Ontario was built at the base of the falls. In 1931, a former Dundas mayor, Colonel W.E.S. Knowles, generously bequeathed monies so that the area surrounding Webster's Falls could be made into a public park.
Dundas also has the Dundas Peak. The Peak overlooks Dundas from The Bruce Trail in Flamborough and has become one of the most visited parts of Dundas. Hikers can take the Bruce Trail from Tews or Webster's Falls to the peak and look over Dundas and West Hamilton.
