I just returned from VG and did the trip to the BATHS. The baths and the beach were GORGEOUS!! As for you mom, it is hard to say, How steady is she on her feet an how bad is her heart condition? The walk down is not particulary hard or strenous, however it is a little sandy and can be slippery. Once at the baths one or two spots require she be able to bend and duck. The walk back up is not "strenuous" however it is like walking up several flights of stairs. We had an older couple in our group and they did just fine, but took their time. I was a little winded myself..lol.
