Gordon Hartman [realized] there were no parks where his daughter Morgan, who is disabled, could play. So he decided to build one.

…The park, called Morgan’s Wonderland, cost $34m (£26m) and opened in 2010. Attractions include a fully-accessible Ferris wheel, adventure playground and miniature train. Visitors regularly tell Hartman it is the first time they’ve been able to experience such attractions.

There is also a carousel with specially designed chariots for wheelchairs that go up and down alongside the animals.

…Since it opened Morgan’s Wonderland has received over a million visitors from 67 countries and from all 50 American states. A third of staff have disabilities and entrance is free to any guest with a condition.

…”We open every year knowing we’re going to lose over $1m (£750,000) and we need to recover that through fundraising and partners.”

This year, the theme park was expanded with the opening of Morgan’s Inspiration Island, a fully-accessible water park.

“Fewer people were visiting in July because the wheelchairs got too hot. So we decided to create a water park next door,” Hartman says.

Parts of the island use warm water, which helps visitors with muscular problems. Waterproof [motorized] wheelchairs are provided, which run on compressed air rather than batteries. There is also an accessible river boat ride.
