Im visiting with my grandparenys, so long hikes are not doable. Is there somewhere close to the roads where we can take pictures in the redwoods?

Go to the end and park. Go in just 100 feet for some spectacular views amd to aka pictures.

If you drive all the way in to the day use(less than a mile), you can take a short hike into the redwoods. This trail is well marked an part of it is ADA accessible.

There is day use area with an all access tail that will lead to some very easy trails to walk. Some are even made for a wheel chair to go through. You should be able to get some pictures with very little hiking required.
