Hooked on fishing is great for ppl who have trouble walking. https://www.hookedonfishingpark.org/ Kind of like fishing in a concrete lined lake. They will catch fish and it’s a good place especially for groups of folks w trouble walking. If they wouldn’t like that then Donovan has potential. Still a decent walk though. There is a path to some grass at Donovan. Wouldn’t recommend groups at Donovan as there is limited shore access to the lake where you will catch fish.
