Mio, part of Northern Michigan, is situated in the Au Sable River Valley. It is surrounded by the Huron National Forest and near the Rifle River State Recreation Area.

Mio-AuSable Schools is a Kindergarten through 12th grade school, with all grades contained in one building. Middle school and high school students are enrolled in seven classes each day, and the year routine follows a semester schedule. Mio-AuSable currently offers two Advanced Placement (AP) courses, AP Biology and AP Calculus AB. The school does not offer any Honors courses, but to make up for the lack of advanced classes, students are encouraged to dual-enroll through Kirtland Community College. Sophomores, juniors and seniors can choose to take online classes through the nearby community college, and if the students receive at least a C in a course, they will be granted college credit in that course which may transfer into the university of their choice after high school.
The high school has about approximately 170 students and 17 teachers, some of which double as middle school teachers. The current superintendent is Paul Ciske. The high school and middle school principal is Dennis Niles. Both the superintendent and principal got their positions in 2018, following the retirement of superintendent and high school/ middle school principal Jim Gendernalik. Kelly McDonald is the 6th through 12th grade counselor, and Jeanette McVeigh is the administrative assistant. Paul Ciske also acts as the elementary school principal. The Mio-AuSable school board is composed of seven members who meet on the second Monday of every month in the school auditorium. The members include Penny Irelan, Mary Lou Hunter, David Lashley, Jessi Mitchell, Cheryl LaVigne, Amy Fullerton, and Lizz Holzwarth.

There are two historical markers in Mio.
- Mio Hydroelectric Plant was built in 1916 on the lower Au Sable River. William W. Tefft, a Consumers Power civil and hydraulic engineer, invented and patented the so-called "conduit spillway", which channels excessive flow through channels built into the plant. This was the first plant to use it, and it is cheaper than other forms of spillways. 
- Oscoda County Courthouse was built in 1888.   It was destroyed by a fire on May 5, 2016.
- Union Corners is an abandoned "town" situated on Valley Road in Mio, Michigan. It was abandoned in 1882 when its county government moved to where downtown Mio is now located today. Originally, it was a small farming community. However, the farmers moved from the area because of the poor soil quality. Today, there are very few remnants of Union Corners besides a plaque where the town used to be located and various grave sites throughout the area. Some of these grave sites belong to members of the Union Corners community.
- Hinchman Acres Resort has been providing a place for families to come for vacation since 1933. Originally the vision of Chapin and Lera Hinchman, Hinchman Acres Resort is a camping ground with access to the AuSable River, with facilities for canoeists, rafters, and kayakers. In 1965, the Hinchmans parted ways with the resort. Since purchasing the resort from Ed and Doris Holloway in 1971, Sam and Natalie Giardina have managed the Hinchman Acres Resort. 
- The Timberland Quilt Trail. In 2001 Donna Groves of Adams County, Ohio started a national movement by painting a quilt block on her barn to honor her mother who was known as a "master quilter". Shortly after people everywhere started to do the same until the Timberland Quilt Trail became a national movement. In early 2012 the Timberland Quilt Trail started in Mio, Michigan. Along with more than 30 other states and multiple counties. Mio, Michigan has helped to contribute to the 3,000+ registered quilt blocks throughout the U.S. Many people want to participate in the Timberland Quilt trail and you might even find "Volunteer" quilt blocks in Mio. Although the "Volunteer" quilt blocks can be found in Mio, they will be found on private property and they are not part of the Timberland Quilt Trail. Every summer multiple quilt blocks are added to the Timberland Quilt Trail and can be viewed from the adjacent public road. https://web.archive.org/web/20181024192305/http://oscodacountymi.org/timberland-quilt-trail/

For nearly eighteen years, Mio was thrust into the local and national media spotlight due to a case involving two Detroit-area hunters who went missing in the fall of 1985. On November 21, 1985, childhood friends David Tyll and Brian Ognjan were beaten to death with baseball bats outside of a local bar. The case was eventually cracked in 2003, when two brothers, Raymond and Donald Duvall, both from South Branch, MI, in Iosco County, were convicted of murdering the pair near Mio. It was rumored that the murderers had disposed of the bodies by feeding them to pigs.  When the two brothers were sentenced to life in prison without parole, Tyll's father said, "They took my son. It doesn't bring him back, but it's something."  A true account of the crimes was detailed in a 2006 book by Tom Henderson, titled Darker Than Night.
In 1973, a polybrominated biphenyl (PBB) contamination event caused farmers in the area to destroy their herds. This event contaminated various animals including cows, pigs, chickens, and sheep when a dock worker accidentally shipped five hundred pounds of fire retardant "Fire Master" instead of the feed supplement called Nutrimaster.  Shortly after, the farmers noticed deformities and sickness among their livestock as well as the newborn calves. More than 35,000 cows were contaminated and destroyed. Out of these, 1,300 were dumped into a clay-lined pit in Mio.  As of 2014, PBB is still detectable in some blood tests of people in this area.
