I have walked the entire pathway without any fatigue and I am 79 years old. There are benches to rest if you need.. I estimate there is about one mile if paths.
Depends on how much u want to see. Its on both sides of road there are places to sit and rest on the river side.
They also sometimes have a golf cart to take people from the parking lot to across the road where the majority of the sculptures and landscaping is. Maybe calling in advance could let you know if they are offering this service on the day you're interested in.
About a half mile from the ticket counter in the parking lot to the gazebo on the Peace River.
Not much
About a mile
