I want to get a good picture of Grand Prismatic. We will be coming from the South on Grand Loop Road. How hard is it to find the trail? I found it on Google Earth, but I don't think it will be that easy in real life. We will be coming from the Lake Hotel/cabins area. Also, once we find a place to park, how hard/long of a hike is it to get a good picture of GP? Thanks for any info/tips you can give me. Coming to the Park May 20th-24th.
