Riparian Preserve Rules

Use of the Preserve

The Preserve is designed for community use and enjoyment.  Our trails connect to the Gilbert Trail System, and are accessible from various gated points of entry on all sides.  Horses are allowed on equestrian portion of these trails, bikes are allowed on trails and sidewalks, and leashed, well-managed dogs can accompany walkers in all pedestrian areas. The Fishing Lake at Water Ranch is managed by the Arizona Game and Fish Department as part of their Urban Fishing Program.

We offer ramadas, gathering areas, a dinosaur dig site, and campsites, but these are often also used for Riparian Institute programming, so to ensure availability, please reserve in advance.

We are a wildlife preserve and cannot allow large group visitation without prior authorization.  For groups of 30 or more, please complete the large group visitation application. This also applies to organized groups, such as school programs, of greater than 30 directed to visit the Preserve on their own schedule, but during a specified range of dates.

For organized groups of 70 or more, the full common area must be reserved at the above rate,
and must be scheduled at least two weeks in advance.
