There are so many activities that work for the blind. Anything except driving a car :)

So many crafts are easy to modify. Crocheting and knitting even - if she knows how to do those she can still do those. Or making jewelry. Or a tactile scrapbook.

Cooking or baking could be a fun activity together. Follow a recipe, measure ingredients together, chat about anything while cooking.
And sharing some nice family recipes and cooking secrets.

A nice walk or other sports are fun together. Walk with her pace. Or find exercise equipment that can work on other times too. Most gym equipment work easily. Having music for sports can make a difference.

So many games can be played inclusively. Maxiaids.com has many ideas - you could get a few brailled bingo boards (if she can read braille), and - well, I see no reason why brailled games couldn't be enjoyed by the others too.
A Reizen ball with bells could be fun for all - as long as everyone likes a bit of exercise.

How about some poetry or book reading? Or music... Play together or find a band.
Find out if she's a member of the talking books program. If not, it could be fun: get audiobooks in mail, listen to them in her pace so she can read everything she likes (handsfree too - audiobooks can be so much faster than reading braille)
