Birdwatching is an accessible hobby that brings pleasure to many people who have disabilities or have mobility issues. The RSPB (Royal Society for the Protection of Birds) works hard to make its many reserves accessible. They have a section on their website dedicated to birdwatching with a disability. The RSPB’s reserves are listed on their website and all have accessibility information against them. There are also links to external accessibility guides to their reserves, like this one that looks at their Leighton Moss reserve, in north Lancashire.
Bird watching is a hobby that you can enjoy almost anywhere. Some of the best birdwatching can be in your own garden or in a local park or open space. Every year, the RSPB runs the Big Garden Birdwatch towards the end of January, highlighting the accessibility of watching birds, but also providing a useful data gathering exercise for the organisation itself.
