I walk 2-3 miles most days on the mulch trail (once around is one mile) when it isn't too hot and muggy. My belief is that the mulch track is better for the knees, back and feet. It is a huge, beautiful park with lots of lakes. Boats can be rented, kids can play on the playground, and people ride the many bike trails. There are plenty of sheltered picnic areas. I have seen guided walks which I guess are to check out the many birds and other wildlife. I have also seen guided groups on scooters. I would contact the park for more info on the times those activities are available.
