Linn Park Adventure Playground, on the South Side, is a one-off in the city, catering for children with additional support needs.
With both indoor and outdoor play facilities it offers respite to parents and a fun educational space for Glasgow's ASL (Additional Support for Learning) schools.
Lorraine McCabe, centre manager, believes the park is a vital resource for city families.
She said: "The park is open to everyone, but it is specially designed for children with additional needs.
"Children use play to learn and experience the world around them but you don't realise how much a child's freedom to play can be taken away from them.
"Here, they have a safe space to run around and play. They have the freedom to just be children."
During the week the playground, run by Glasgow Life, is used by 16 ASL schools, and at weekends it is open to everyone - meaning families with disabled and non-disabled children can all play together.
Mum Carol McInnes takes her son Ross, nine, to the playground, and he also visits with his school, Howford.
Carol, who also runs a youth group for disabled children in Pollok Community Centre on Saturdays, said Linn Park is valuable for her family.
The 40-year-old said: "Ross has autism but at Linn Park he can just run around and make noises and no-one looks twice at him.
"He has the freedom to just be himself when he's there, which is great.
"It also has some fantastic staff - and is very highly staffed - so I know he is always well looked after."
Linn Park playground was opened in 1983 by the Princess Royal and now has specially designed play equipment that is even wheelchair-friendly.
Its indoor centre hosts two youth clubs for youngsters aged five to 12, and 13 to 25, held on Tuesdays and Fridays.
Lorraine added: "Parents of children with additional needs can often feel judged if they are out and about, and their child is doing something out of the ordinary.
"As a society we are slowly coming round to the idea that there are all differnt people in the world but there are still some people who will stare.
"Parents can relax here as they are all in the same boat. And relaxed parents make for a relaxed child."
To celebrate 30 years helping Glasgow families, the playground, on Netherlee Road, is hosting its fun day from noon to 4pm on Saturday, October 5.
The event is free and all children are invited to get involved.
There will be pony rides, mini zoo, a balloon artist, cake and candy, arts and crafts, face painting and indoor and outdoor play sessions.
There will also be a secret garden, giant snakes and ladders, climbing frames and sand pits plus a Butterfly Garden.
Organisers also said they need help building their Bug Mansion.
Glasgow Life chairman, Councillor Archie Graham, said: "Linn Park Adventure Playground is the only park of its kind in Glasgow and as such holds a special place in the heart of the many families and schools that regularly use it.
"It is a place where those with children and young people with additional support needs can play and have fun together as a family, while enjoying the company of other families.
"We are all increasingly aware of the importance of learning through play.
"Linn Park plays a crucial role for schools in the city, offering them a place to bring pupils to enjoy activities outside of the classroom setting.
"Many of these young people also make use of the facility in the evening attending youth clubs or during free play sessions at the weekend.
"The hugely beneficial impact this has on the young people and their family is clear for all to see."
The Lord Provost of Glasgow, Councillor Sadie Docherty, will be visiting the park to help with the celebrations. She added: "I'm very excited about the upcoming open day at Linn Park Adventure Playground. I've visited many times and always left with a smile on my face.
"We are eager to ensure that anyone who could benefit from using the facility is aware of the many services it offers.
"We are also keen to look at ways of assisting with refurbishing the facility to ensure generations to come continue to benefit socially, intellectually and creatively from the wonderful service provided at Linn Park."
