Child Friendly Off road around Portsmouth??

Mark, There are some family routes at Queen Elizabeth Country Park, which is to the north of Portsmouth on the A3. A bit further north is Alice Holt Forest Park which also has easy routes plus other activities. The are some maps on the Hampshire CC website which you can download as well.

There is a nice "Sustrans" route called the "Hayling Billy" near Havant, drop off at one end and pick up at the other, or picnic and return...http://www3.hants.gov.uk/haylingbilly.pdf
