Establishment of MRVNA was begun in 1975; eventually the park reached its current 850 acres (3.4 km2) of forests, fields, creeks, and ponds.

A long connector trail extends north from the Lenape Trail to Papermill Park (a public park with ball fields, a jogging track and playground, located at the intersection of Paper Mill Road and Polly Drummond Hill Road).

MRVNA borders and connects with two portions of White Clay Creek State Park: the Possum Hill area on the northwest and the Judge Morris Estate on the southeast.

Most recently it has become possible to proceed from the northeastern corner of the park, at Smithmill Road, to the northwest along Middle Run via a recently established trail northwestward amidst residential areas, ending at Curtis Mill, from which one may reach the northeasternmost sector of White Clay Creek State Park by crossing Paper Mill Road.

This last trail is shared with White Clay Creek State Park, thus allowing connection across Polly Drummond Hill Road with Judge Morris Estate.
