Rock Island is easily accessed from I-40, exit 288 or I-24, exit 111, located 15 miles southwest of Sparta.
We visited Twin Falls. I'm not sure how they intersect with Rock Island State Park. I was a little confused as if Twin Falls is located inside Rock Island Park or if they are two separate parks. We didn't hike anywhere other than where we could see the Falls. So I can't say about the other areas. But where we were, the parking is scarce. Maybe 10 spots at the most. There also wasn't any restrooms .
10/10❤️Waterfalls are seriously insane!! So amazing. There is several ways to get to the most popular falls. Most GPSs will take you to the parking lot right by the gorge trail(by the fairy house). This is a nice spot to see the other smaller falls/rapids from the parking lot, can see the fairy house, abandoned building, read park info, and has bathrooms. HOWEVER… this is sometimes closed… there is another road that will take you right up to the falls… basically the end off the gorge trail. No hiking even necessary to see the falls from the other parking lot. (This is where my pictures are located, down the second parking lot). The visitor center has great information, bathrooms are clean, and staff is friendly. Park is kid and dog friendly. Note: getting right up to the falls is hard for a dog. Could’ve gotten closer up than the pic but my dog could get over the rocks.
This place was great. Our favorite trail was the Blue Hole Trail. It's not for the faint of heart and you definitely want footwear that can get wet but it was great. We also really liked the Great Falls Trail. We went down and walked behind some of the waterfalls which was awesome.
This is such a magical place. To see the waterfall flowing out of the side of that ridge is breathtaking. What makes it even better is that you drive 6 miles to the other side of the river and see Great Falls. Twin Falls has more height, but Great Falls is so powerful. You get a Twofur in one trip.
