Although a bit of a bumpy drive to get there, it was well worth it! Approximately a 7k hike to see all aspects of the area including the waterfall, lake, hot springs, and chemical reaction point (although you can just do 2k to see the waterfall if preferred). We did this without a tour guide and it was fine to do so. The trails are pretty straightforward and you can do it at your leisure. Beautiful scenery!
