Ka'au crater hike. Feb 6 2016. Muddier, longer hike than anticipated. Kendra's dad (in town on business) drove us down to the southeast side to do this hike. 2 and a half hours later, we made it to the falls, muddy barefeet and legs and all. The waterfall was WELL worth it though. We played in the fresh water and snapped a bunch of pics before heading home. Well spent Saturday for sure! Love my girls.
