Just because I've been there and done it doesn't mean that you can. You know your limitations, I don't, so if you go there it is at your own risk. By mentioning the place I'm not suggesting that you go there.
Arne Road, Wareham, Dorset, BH20 5BJ
all terrain mobility scooters can be pre-booked at Arne and are provided by Countryside Mobility
Off-road, or all-terrain, mobility scooting around RSPB Arne in west Dorset was one of my first ever experiences of off-road scooting, before I even had my own off-roader and remains one of my favourite places to do it. I hired an off-road Tramper directly at RSPB Arne, the Tramper is a make of off-roader, they call it an all-terrain scooter, and was supplied to them by the charity Countryside Mobility, if memory serves me correctly the cost was only £5 for a couple of hours, but check directly with RSPB Arne.
Almost immediately beyond the Visitor Centre, where, if you've booked with them, you can collect the Tramper, the terrain becomes rough, and you may find yourself scooting over tree routes, but the Tramper, with care, is able to get over them. For me, with little experience of off-road scooting at the time, and no experience of RSPB Arne, it was a superb and exhilerating experience to no longer be hampered by not being able to walk more than a few yards, and even those in pain, and in such an amazingly beautiful location!
From the edge of the woods, and beyond, the paths open out with wonderful views of Poole Harbour, and, if you happen to be there at the right time, colourful splashes of heather. From one of the several trails you can get views of Corfe Castle. Of course RSPB Arne is also about the wildlife, especially the birdlife, and the Visitor Centre can tell you what bird species have recently been spotted.
There is no entry cost for visiting Arne. There are car parking charges, which will displayed on the information board.
