The Hough playmaker enjoyed his trip.
"My visit went great," said the 5-foot-11, 180-pound Groulx. "Obviously it's a long process, but I could see myself there.
"My favorite parts were touring the facilities and going over plays and routes with (wide receivers) coach (Ted) Gilmore. I also went to see the business school and toured the campus."
Groulx spent the most time with Gilmore and assistant coach Saeed Khalif.
"They went everywhere with me the whole day," Groulx said. "They told me they see me running the ball, playing in the slot and out wide.
"They were very interested and wanted it to be the place for me. I really like that about them."
Before leaving, he spoke one-on-one with head coach Paul Chryst.
"We talked for about half an hour and I thought the conversation went great," Groulx said. "We talked about a lot of things -- and not just football. He told me that I was a well-rounded athlete.
"He told me Wisconsin is a place for well-rounded athletes that like to work hard. He also said the game atmosphere is incredible and that the fans are dedicated to football."
Although the Hough standout plans to take other visits this summer, he does not have anything scheduled yet.
Groulx finished his sophomore season with 108 catches for 1,853 yards and 24 touchdowns.
