Rainbow Falls was our first stop on our trip to Hilo. We were promised by the AAA book that there was going to be a great spectacular fall, and rainbows. However, when we arrived the water was more of a trickle than a water fall, we also didn't see any rainbows. This does not mean you shouldn't make a stop here. We took a scenic hike down to the area of the waterfall, through the lush rainforest and did some sightseeing. I believe you have to go a certain month of the year to get a water show, and we weren't in the correct month. Overall, it's still a beautiful spot to stop by and take a quick hike.
