While we're doing grand (bigger is better after all), here's Grand Prismatic spring, which is a large colourful puddle. In order to see it all you have to climb an adjacent hill (preferably on a hot day to minimise the water vapour), or fly overhead. We absolutely didn't want to kill the inlaws (sending bodies airfreight is very expensive!), so we stuck to the local boardwalks.
