Olst-Wijhe (pronounced [ɔlst ˈʋɛiə] ⓘ) is a municipality in the province of Overijssel, eastern Netherlands.

Traditionally, agriculture (fruit and cereals), cattle, meat processing and the production of bricks in open-air brickworks along river IJssel were the prime sources of income in the area.

There are cable ferries between Olst and Welsum and between Wijhe and Vorchten in the municipality of Heerde (there is no direct connection between Marle and the rest of Overijssel).

They are called wetering ("drainage waterway") and are amalgamations of natural streams gradually channelised from the 18th century onwards and specifically dug canals[5] .

All these streams flow in a south–north direction and come together at one point or other to eventually form the Zwarte Water river near the city of Zwolle.

The mansions themselves are generally still inhabited or used for commercial purposes and so cannot be visited, but their grounds are open to visitors to stroll around.
