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.
Brean Down, Brean, Somerset, TA8 2RS
Brean Down is a promontory, technically known as a "sticky out bit", from the coast of Somerset. It rises over 200 steps and beyond to a height of 318 feet and stretches about a mile from the steps to the fort. The far reaching views to Burnham on Sea in the south, and north to Weston Super Mare, as well as out to sea, are the highlights along with the fort at the far end. Brean Down's fort was built to defend the country against a possible Napoleonic invasion. The fort is now a 'restored ruin', you can still wander around the buildings.
The earliest signs of life date back to around 10,000 BC. with bones of extinct creatures such as mammoths and woolly rhinos found there along with the archaeological remains of a Roman temple along with an Iron Age hill-fort.
I hired a Tramper, provided by Countryside Mobility, to go up via a steep access road to the east, but when I asked I was told that it's possible to borrow the key required to open the heavy/difficult farm gate at the foot without hiring a Tramper, ie if I'd taken my own off-road mobility scooter.
