This is a terrible trail. It is not marked at all so you end up walking on game trails half the time. The trail has not been cleared for years and has thorns everywhere and a ton of fallen trees blocking the trail.

We only did the Hamilton iron works trail which was only .2 miles. Nice short trail with cool structures but came out with hundreds of tiny ticks.

trail is not marked at all. we took the wrong way. Don't go up the huge hill multiple splits in the trail. we ended up walking into a multi million dollar home out in the middle of nowhere. Ended up walking the road back and started over finally found the 1st cave which is across the creek. never made it to the end cause ran out of daylight

one of my favorite hikes.very remote part of the park. not a difficult hike but not for hikers who don't enjoy getting creative with their paths. no trailblazes and often very little trail. i would recommendnot going on the summer time due to overgrowth and ticks. finding your way through this bushwack is well worth the effort to arrive at the magnificent greens cave.

It's a beautiful hike with lots of twists and turns. You have to get creative in a few spots when passing over creeks. There one spot where the trail disappears and you have to walk the dry creek bed until it reappears. That was challenging. And be prepared for wet shoes during the rainy season. It can be hard to get across the different wet areas.

Also, the ticks! Holy cow! Brushed about 10 off me during the hike, picked off 11 when I go home.

But, the cave and its surrounding areas make it worth it. Beautiful!

2 words--Tick Repellent!

Now, as awful as this report might sound, I LOVED this trip. We used this trail to get to the bluffs at Green Cave to do some rappelling (advanced permit required). The Green River was running very high, and we ended up having to catch a ride with some drunk canoers to reach the cave & its bluffs. Only problem was by the time we were done with the day, all the canoers were gone. We ended up having to swim up river for a few hundred yards, carrying 60lb packs. A buddy drowned his cell phone in the attempt.

When we got back to our hotel that night, we were CRAWLING in ticks. By that, I mean we used up a roll of duct tape, using strips of it to pull ticks off our arms and legs--there were far too many small ones to pull off one at a time.

This trip was great! I really did love it, but should I ever rappel at Green Cave again, I'll rent a canoe and float the river to my destination.

One of my top 5 in the state. Caves, springs, old homesteads, vistas of the meramec river. Greens cave and bluff are the highlights of this hike. Greens cave with its 124ft enterance-is breathe taking. There is no designated trail to any of this, if you are not comfortable with land navigation, don't try it.
