Horribly marked trail. Only went a little under half mile in then turned around. It was a little later in the eve to risk it.

This is one of my favorite hikes just follow the stream up and then there is a nice rock to climb with a great overlook. Head back down the same way.

This was a very nice trail to hike. It was rather difficult at times so I had to carry my 4 year old. Not sure why this is called kid friendly. We came across a copperhead so watch your step! Be prepared to cross water several times.

Great scenery once you get to the top but very steep and rocky towards about the halfway mark. Lower levels were very washed out and muddy but great nature walk. There was no good spot to cross the stream at the very beginning but we got creative and balanced across the fallen trees, which the kids enjoyed very much. No real good places to stop for rests but overall a beautiful trail.. well worth getting the whole way to the summit!

This is a fun short tail that gives you opportunities to hop over rocks and small waterfalls at the headwaters of a creek. There are also opportunities for light bouldering on the quartzite outcrops at the top of the mountain.

Great hike! Don't follow the blue trail markers, that leads you the wrong way. Just back track the water flow towards the right and you'll get to the water fall. We went past the falls and climbed the rocks.

Went just after a rain! Beautiful and lush, the stream and falls were wonderful! Parts of the trail along the stream were a bit tricky with wet rocks and logs across the path but it's manageable and worth it! Could have stayed and listened to the sounds of the stream for hours! Natures music

The out and back style route is a nice little hike

I don't suggest taking the loop route that this trail is currently marked as. The hike up to the ridge line was fine but poorly marked. Trail became nonexistent a little past that.

Like everyone said, ruined. The view sparkles in the day time from all the broken bottles.

I've been here many times over the past 20 years. It used to be a nice and quite place. Now it's always packed full of people and no longer enjoyable. If you drive by and their aren't 20 cars jammed into the spot it's worth a stop!

This is my favorite hike in the world, but I'm probably being a little biased :p There's a beautiful rhododendron forest along the creek at the foot of the incline, and the hike up the mountain stream makes it a perfect hike during that unbearable summer heat! I've run into a few other hikers here and there, but I just did a snowy winter hike and saw only footprints. The outcrop at the top gives you a 360 degree view of nothing but sky and trees. Amazing!

Very scenic to hike up the stream, but beware of the posted signs. Also, not well marked at all. Beautiful views from the top.

nice hike

Tumbling Run Game Preserve is a privately owned area and is marked no trespassing around the entire perimeter. As the area is used for hunting and shooting sports there is a danger if the signs are ignored. Please use the Trails that are marked for public use like the Blueberry Trail and AT. Lewis Rocks is off limits as it is on private property as is most of the falls. Thanks

By far one of my favorites! Just did my first winter hike here and I fell even more in love with this place. Half the fun is finding your own way as there are very few markings and lots of different paths people have created. I just stay close to the stream and hang a right at the top waterfall to access Lewis Rocks. Snakes are common so be cautious. Give yourself plenty of time to explore! Absolutely beautiful in any season!

Trails are not marked, not even the trailhead. No ample parking. There are a number of residences and they have their own trails to their own favorite places. Not a great trail.

Trails weren't at all clearly marked & crisscrossed in every direction. It was nice to hike by a stream, but you could hear the cars on the road that is close by which detracted from the hike in my opinion. Listening to traffic while hiking isn't that relaxing:-/ I love hiking on other trails in the area though!

Perfect! This can be tricky for first timers since there are many trails and none are marked. But all the trails means you can come back many times and try new trails. I've hiked much of Michaux State Forest, and this is definitely my go to spot! Back story on the posted signs and trails (my understanding), maybe 20 years ago one main trail was shown on state forest maps (now on some maps as Forest RD) which intersected the Application Trail - which used to loop down inside the game preserve. Later the AT was rerouted straighter above the game preserve and no trails where printed on state forest maps, and no signs were posted. About 3 years ago a hiker injured their ankle and needed rescued by helicopter. Tumbling run ended up paying some of the bill. Now it is posted for liability on their end. You can hike here, but they disprove of litter and irresponsible hikers. So, pick up trash and be smart about it. To access Lewis Rocks from AT (using the old AT and old trail that is Forest RD) turn right at the crossing of Forest RD, both forest roads are connected. Take that to the top of the mountain where Lewis Rocks is marked, and follow the trail on the right, which will go along the rocks, down into the preserve and falls. This route is tricky to navigate being its not marked. You might want a good gps for this old route. You can also take Blueberry Trail from AT to the bottom of the game preserve. To access Lewis Rocks from 233, is tricky. Park in the lot, cross the stream. There's half a dozen routes that all go to the same place, some easier then others. The simplest is to hike along the stream. Follow any path to the falls, then hike up the steep on the right, continue to the top at Indian Rock where you can see a great view. To the left are more rocks you can follow. There are many campsites in the rocks, not that you should use them. You can also take Forest RD back down into the parking lot.

This is my absolute favorite hike on the entire eastern part of the United States. I've been hiking here regularly since I was a kid, when my father took me here in the early 90s. The way up is spider webbed with many different intersecting trails to choose from, and depending on which ones you chose, you can make the trail easier or more rocky and challenging. even up at the pinnacle you can choose to climb up or hit any of the side trails to avoid having to crawl up rocks. the views all along the Ridgeline offer amazing perspective and give you a different experience every time you come up. I would recommend this trail to anyone who is okay with a bit of a challenge as long as you keep an eye out for the copperheads...which are very beautiful in spite of their slight danger. they aren't necessarily deadly, however their venom is hemotoxic and you would have to hurry to the hospital to avoid serious health complications if bitten. If you are a hammock camper, this trail offer absolutely perfect campsites all around and depending on the season, a simple wind shielded campfire is safe. If I could choose just one trail to live on forever, this one would be it!

The blue blaze trail is not faint of heart or novice

Trashy, graffiti and nothing to see

Thursday, June 23, 2016

I'm dying to go here and hike, however I can't find any information about the game preserve to contact for permission. Can anyone share who to contact?

it was a good hike

Ive hiked this trail 100 times and it never gets old. Beware of Timber rattlesnakes at the top of the hill around the rocks. They tend to sun themselves on the slope facing 233 at the top of the hill. Stay on the trails!!

the best hike I've found in S. central PA! the waterfalls and pools add to the gorgeous hike up this mountain. on the way up there are flat rocks you can sit on and eat lunch. this is definitely a hike I would consider moderate-hard. There have been many reviews about people encountering snakes, although we have not, this far. I brought my children with me, youngest was 5 years old, although she is a tough cookie, she made it up and down but I do have to say, you must watch your kids carefully b/c of the mention of rattlesnakes, etc as well as the rough steep terrain in many parts. We carry a walking stick with us (in case of snakes) and other precautions such as first aid kit, etc. Good advice would be to stay ON the trail. With all that said, this is a MUST hike trail!

I really love this hike! The trail is confusing but if you just follow the stream, you'll eventually see the falls. Watch out for rattlesnakes though! Just saw one today and had a little scare. Just be careful and enjoy the hike.

Very fun hike but can be very confusing. Once you get to stream there's multiple paths you can go and have to cross over the stream constantly. I stay on the right side of the stream for the most part. Pretty steep once you get toward the top and there a set of rocks on the right for a great overlook of the valley. This hike is a hidden gem for sure.

Saturday, April 02, 2016

great trail, at first you start out with a cool view of the small falls. it's definitely fun trying to find ways over the stream to the other side of the trail!

Awesome views! The waterfall is spectacular!
