Take your time to walk the rim and experience the sounds, smells and views around you. The colours in the rock faces caused by Hot spring activity are wonderful and the lower Falls are a sight to behold. If you stay at Canyon lodge and cabins there is a wooded path to Grandview point just 15mins or so away, from there we walked the north rim. We spent 5 hours in total and it was worth every moment, even in the rain ! Plan to spend at least 2 or 3 hours to enjoy it. You can drive along the rim and stop at various viewpoints if hiking is not your thing.
