The Riddy is currently open to the general public; although some of the paths are reasonably rough, the site is most accessible via the riverside path: a disabled access gate is provided as well.
The River Ivel may be fished from the reserve border, but a permit from the town council and national rod licence are required.

The Riddy is a remnant of this previous network.
In the thirteenth century CE, the area now known as The Riddy was referred to as "Parkesriding".
In the north-eastern corner of the reserve, a mill pool can be found; whilst the last mill was built here in 1857, evidence shows that mills have been built on the Riddy since at least
