Nice forest and very well maintained. Pretty easy and can be done about an hour. Check out the spring castle on the way back.

Great trail for beginners. My friend and I hiked this one while we waited for the rain to clear so that we could hike down to the falls. Mostly shaded by trees so even in the rain we didn’t get soaked. Maintained very well too!

We only did a very small part of the trail because t started to rain. We started on the Access Trail, which is 0.3 miles, and crossed over to the nature trail. It was scenic and perfect for a miniature stroll with our pups. The weather just didn't want to cooperate. We will be back though!

Rock Island is beautiful! The water was cold and refreshing! We went as a family and really enjoyed it. It was busy, which I didn't mind, but the litter was out of control! IF YOU TAKE IT IN, TAKE IT OUT!!!!

Breathtaking falls (though they don't occur naturally). Lovely surroundings and trails add to the experience.

Easy but beautiful.

Absolutely breath taking views. trails were well maintained. tons of really cool plants and insects to see along the hike. not terribly strenuous but definitely will get the heart rate up. would have loved to be able to find how to get to the other side with the falls. but still beautiful view from across the river.

One of the best places I've ever got the chance to explore.

This trail does not have the natural features to draw hikers that other hikes in the area may have, but it is a nice hike nonetheless. It is an easy hike without much elevation change.

An interesting feature, located approximately 0.25 miles from the end of the north side of the loop is a family cemetery plot dating back to the late 1700's with reference to the War of 1812 and the Civil War.

This trail I feel gets overlooked at Rock Island, as it does not contain and running water/waterfalls as the others near the gorge do. However, it is an ideal trail for running, or for an extended walk.

Walked the overlook trail which is a terrible overlook with my 2 and 3 yo. It's just a short distance from the parking lot. Then we walked the blue hole trail. The main trail in front of the twin falls is also good for small children. There is also some things to see at the great falls parking area.

Nice but somewhat boring

Nice trail. My wife and I are in our early sixties so the trail was moderate for us. Lots of shade and you can see the Collins river in some portions. View doesn't change much. Lots of butterflies in the parts under the power lines.

Easy trail for the family. Mostly shaded and an easy walk. Would be a great trail to begin training for cross country running.

Beautiful but fairly boring.

We hiked the Collins loop which was super long but beautiful except all the spiders! Then we travelled the upstream trail to swim a while. Fairly easy hike but well worth it!

The trails and park are beautiful! However, found the trail marking was not as consistent as we would have thought, especially on the Blue Hole trail. Blue Hole is also treacherous with lots of slick spots and rock climbing.

It was great we hiked a few trails...old mill trail which was worth the trip down to the rocks although seemed pretty dangerous with all the slick rocks. Very beautiful. Also hiked blue hole and the downstream of twin falls. Be prepared to walk on and around rocks use hiking shoes and good tennis shoes (no flip flops) on these trails, bring water to drink because it will make you sweat hiking down those rocks and many steep steps to climb!

Nice trail, and very peaceful. There were a few others on the trail when we were there, but it wasn't congested. Not very scenic, as far as waterfalls or rock formations, but lots of wildlife in the area. I would recommend this trail for everyone, not too strenuous.

we camped here for 3 nights, spent one day hiking on some of the trails, we started with the Old Mill Trail, it was down some steep steps with water running down them. when you reach the base is like another world! still under the tree cover it's cool and misty. once it from under tho and you start walking on the rocks! HOT HOT HOT! the cascades leading down to a swimming hole are beautiful. the word cold doesn't even begin to describe the water! we drove around to powerhouse Rd after that, walked down from the parking lot and across tons of boulders to the edge of the great Falls, they were incredible! coming out of the middle of the cliff wall. we them hiked the Upstream Trail and it took us back to that swimming hole. it was a fairly easy hike, until you're at the end and you have to climb down to the bottom. we then hiked part of the downstream trail. but we were hot and tired and ready get back to camp so we didn't finish that one. we now have to go back and hike all the ones we didn't get too

Beautiful park! Downstream trail is moderate- allows you to see little falls and twin falls. Upstream trail will take your to the greater falls where many people swim- is slick and rocky... and you WILL get wet, so dress accordingly and have fun!

Down Stream Trail at Twin Falls is awesome. There is a hidden cave with a great falls.
