Hi Ellen,
Unfortunately most of Ecuador is not very handicapped-friendly. I say most, because there are a few businesses and areas within cities that are making strides to accommodate those in wheelchairs or with other mobility issues. Sadly, most sidewalks, bathrooms, and buildings are not equipped for easy handicapped access. Things are changing and awareness is raising, but I think it will still be some time before I would consider Ecuador a handicapped-friendly country.
