As we don't seem to be able to find extra people for the sacred earth tour @ $595.00 & that is way too expensive for the 2 of us, I'm hoping someone has some suggestions for us to do a day trip by ourselves. We have a car. I'm not a big hiker but my partner is, so we'd be happy to do a few hours walking. I hear the south rim is the most beautiful.. Is it sign posted? Is there a short park ranger tour from the actual canyon? We would appreciate any suggestions or tips..
