High Peak Liberal DemocratsRoy Taylor has Motor Neurone disease, and is travelling in a four-wheel-drive wheelchair.
An RSPB manager is undertaking a 215-mile (346km) coast-to-coast trip to help raise money to "get rid of obstacles" to give the disabled greater access to the countryside.
Roy Taylor, has Motor Neurone disease, and is travelling the Trans Pennine Trail in a four-wheel-drive wheelchair.
Mr Taylor left Merseyside on Saturday and expects the trip to Hornsea, East Yorkshire, to last 10 days.
The money is to be used for access at the nature reserves where he works.
Mr Taylor, an area manager for the Royal Society for the Protection of Birds, said he could "hobble a few yards but was effectively wheelchair-bound".
He said he would be auditing all RSPB nature reserves in northern England and drawing up a list of changes from installing wheelchair-friendly access points to better views from hides.
Mr Taylor, of of Denby Dale, West Yorkshire, said: "I can't change what happens in the wider countryside."
In his wheelchair, he said, he finds he cannot pass gates, stiles or steps on some routes.
Mr Taylor said he had also had to move house in order to get better access to a route he could use to walk his dog.
The Trans Pennine Trail central office said it wants to removes access barriers but has no power to force local authorities to do so
