Yes. There is a direct path to Devils Bay from Top of the Baths. Easy hike down. I think the narrow ladder stairs and crouching down might be a challenge coming off knee replacement. Water depth is not an issue. Also, note that they are trying to enforce a one way path through. So if you hung at Devils Bay and others went through, you might just have to meet them back at top of the baths, or they could hike up and back down to you.
