The hanging bridges at the Rainmaker pale in comparison to the length of the bridge at Los Campesinos. But, there is only one bridge at Los Campesinos, while the Rainmaker has many. Still, the one bridge walk was quite exhilarating; if you're afraid of heights, good luck! The waterfall was a trickle but there was enough water in the pool for a dip. We didn't do the hike, just too hot.
You definitely need a 4x4 for the 6km drive off the main road to Los Campesinos. Its a fun and beautiful drive, however, would my wife and I do it again? Maybe not, the drive for the payoff is a bit underwhelming, but we would definitely go back and take friends and family who come to CR.
