There are two types of paths there. Hard packed small gravel and mulch. The main trails seem to all be hard packed gravel which works just fine with wheelchairs and rollators. Some of the wooden "bridges" are uneven (their piers have sunk) so be careful.
The easiest trail has crushed pea gravel and is labeled as handicap accessible. I'm not sure the roller wheels would be great on that though.
They have wood chips on most trails.
