Definitely a difficult up hill at points.. where proper shoes and you're good to go! :) Erin Laughlin (342) 3 months ago N/A: 26 Completed 16 Reviews Glen Onoko is an absolutely beautiful hike. I did it today with snow and ice on the ground. The early morning snowfall had near-perfect snowflakes. Icicles and ice walls are prominent along the run which is flowing with a lot of force. This is a dangerous hike even in good conditions and requires proper footwear. Hiking boots are recommended on the trail. In the winter conditions, like today, microspikes are a necessity. The possibility of slipping on a narrow stretch of icy trail is quite large. Have fun, but be safe... This hike is not recommended for small children who will walk or those not in the best of health. Keyvan Ebrahimi (99) 5 months ago N/A: 1 Completed 1 Reviews I usually don't write reviews on hikes I do, but I have to say; this is one of the best trails I have been on. This is a must do for everyone who adores the awesomeness and purity on nature. Lee Sanders (59) 5 months ago N/A: 1 Completed 1 Reviews Beautiful, popular but deadly hiking trail as some have found out. Very popular especially for those inexperienced out of towners. Nice view but I'd suggest heading farther north to the overlook instead. Jamie Wojciechowski (351) 7 months ago N/A: 5 Completed 4 Reviews Amazing hike that starts out with an easy trail and becomes very difficult as you approach the falls. Trail is not maintained so path can be very narrow in some parts and steep in others with limited support for climbing. Well worth the hike, just beautiful and great place for a quiet lunch. Erica H (43) 7 months ago N/A: 8 Completed 1 Reviews Awesome hike with a few difficult steep spots that make it almost like root climbing. Went on the hottest day of the summer and cooled off by walking in the waterfalls. Stopped at the vista for lunch and made it back down before thunderstorms rolled in. Matthew Maiorana (188) 8 months ago N/A: 7 Completed 7 Reviews Great hike that tracks a stream past a series of falls. Can't swim but can definitely get a good soaking. The kids love this one and we keep going back. Can be very steep and rocky. Matthew Maiorana (188) 8 months ago N/A: 7 Completed 7 Reviews Really great hike that tracks a stream up past a series of small falls. Can be very steep in places. The kids love this one and we keep going back. Karen Frame (103) 8 months ago N/A: 2 Completed 3 Reviews Forgot to rate...4 stars! Karen Frame (103) 8 months ago N/A: 2 Completed 3 Reviews This is a beautiful trail to hike...and a good challenge as well. The three large waterfalls make the climb all worth it. The second falls are my favorite because you can actually walk right behind them and look out through the falls. A great way to cool off too! The trail is not well marked at all...thats part of the challenge. The only disappointment we had was seeing all the water bottles and trash left behind by other hikers. I came down with a full backpack for the recyling bin! And after seeing all these posts about snakes, will be much more aware next time!
