We are headed to Kauai this Friday for the first time, two young (late 20s early 30s) couples, one older couple (upper 50s) + a one year old. We're staying at the Grand Hyatt. We're fairly active, but do have a one year old in tow, any suggested hikes that might be accessible to us in December? We are renting a car so will have a decent amount of flexibility there.
Also, any last minute tips, anything we should know about traveling there particularly in December? Closures, tips, anything exciting this time of year? Must eat at restaurants? Thanks!
