Nice little hike to stretch your legs, after riding in the car FOREVER, before getting to your real hiking destination inside Rocky. Love visiting this little spot. Gets pretty toasty in the summer time. Watch your footing on the slippery rocks near the falls and the loose gravel along the way.

Quick family hike.

Great for families. Did it with an age range from 5-60. Just bring lots of water. It does get a little long so we stopped a few times.

Ok, I feel like I need to "normalize" all the reviews here for this particular trail. It was a great trail and spectacular views, but even if you are in good shape this may be a workout and a half for you. Granted, we are from NY and not used to exercising at 10,000ft... you will notice the slight reduction in oxygen going up this hill. It took us a good 5 hours out and back with several stops to look at the views and a 30 min stop at the top for lunch. We met several other hikers that were having a tough time and one group quit just 30 min from the top. If you are not used to Colorado hiking, bring 2x the water you think you will need and snacks to get you through. Don't get me wrong, it was a great hike but the reviews here make it sound a lot easier than it is :)

Go to 5th lake. Its well worth it. Trail kinda disappears but its pretty obvious still.

Great short hike for kids

Amazing views, beautiful lakes and low traffic after leaving the Adams Falls area. Difficult hike with many steps. But we’ll worth the trek!!

I only saw one trail ranger going down the gravel section in a golf cart. great views and really cold water!

It was quite hilly but the hike was nice and short and the views and waterfall was rewarding.

What wasn't damaged by the beetle kill mitigation project is now sadly burned due to the "Golf Course Fire" in late June early July 2018. It will hopefully be a great area to hike in less then 10 years.

Due to the length of this hike, I’m splitting the review into two parts

Part One: Big Meadow and Ptarmigan Pass Loop Trail, Rocky Mountain National Park (RMNP)

This trail should be on every backcountry hiker’s short list. At around 30 miles (not 25) it can be done in two days (pushing it) or over the course 3 to 4 days (recommended). Let me tell you about it, including its meadows, wildlife and commanding views from Ptarmigan Pass.

The Hike:

I strongly recommend that you hike this trail clockwise. Get yourself the Nat. Geo. Trails Illustrated topo map (#200, Rocky Mountain National Park) and use it to plan your trip. This trail is well marked but you should always have a map and compass before heading into the back-country.

To hike this loop, you must reserve your campsites in advance. Go to the RMNP “Wilderness Camping” registration page, fill out the forms, give them your money ($26.00 USD as of 2018), and pray. When you do get your sites, you must stop at the Kawuneeche Visitor Center to pick up your permit the day of your hike - so plan ahead.

To begin the hike (going clockwise), drive to the Tonahutu/North Inlet trailheads just north of Grand Lake, CO. Park at the North Inlet trailhead (this is where you will exit the loop) and walk the couple of yards back to the Tonahutu trailhead to start the hike.

Day One - Jumping In

Going clockwise, try to reserve one of the following campsites on the West side of this loop: Paint Brush or Green Mountain or South Meadows. Each of these sites borders a BEAUTIFUL meadow with Moose and Elk, as well as a good water source close by.

If you cannot get one of these sites, try for Upper Onahu, Onahu Bridge or Onahu Creek, just North and West of the loop. Of these three Onahu Creek is by far the nicest, though getting to it from the Tonahutu trailhead makes for a 7 to 8 mile first day - a long hoof if you start late.

Day Two - Heading Up

For day two, try to get a site that is as far up the North side of this loop as you can, for example Renegade or Haynach or Timberline. If you cannot get one of these, try for Granite Falls or Lower Granite Falls, both nice, but BEWARE, these sites have had issues with bear activity in 2018.


Day Three - Summit

What makes this trail worthwhile is summiting Ptarmigan Pass. Plan on packing up about 2 liters of H20 (or so), because while this trail is well-watered throughout, the summit has a nearly 5 mile stretch without any water.

This summit is not, especially going clockwise, a tremendously strenuous hike. It is however, a bit of a psychological beat-down. Running nearly six miles from treeline to treeline, it is the pass that seems to never end. Just after Ptarmigan Pass, watch for the sign marking the junction with the Flattop Mountain Trail and turn right to the North Inlet Trail. Down this section of the trail you will see a row of double cairns stretching off and over the horizon - cool but weird.

There is a large, resident herd of Elk that loves this summit. If you are lucky, they will cut the trail in font or in back of you, giving you a “caught in a herd of creatures” Jurassic Park movie type feelings. Again, just cool.

Plan to get above treeline early and watch the skies closely. This section of the trail may take you some two to three hours, and that’s a long time to be exposed above 12,000 feet, especially in bad weather.

On the way down, try to get reservations at July or North Inlet Junction campsites. If these are full, Ptarmigan is OK as well.

Day Four - Getting Out

On the way out plan to stop at Big Pool (shortly after the campsite of the same name) for a killer swim, and Cascade Fall for an awesome view.

Once off trail, but before you leave RMNP and Grand Lake, plan to make a stop at Sloopy’s Grill for great burgers, fries and even fried chicken. It's a bit of a biker joint, but the staff is friendly to smelly hikers and the service is fast - just the ticket!

(Due to the length of this hike, I’m splitting the review into two parts)

PART TWO: Big Meadow and Ptarmigan Pass Loop Trail, Rocky Mountain National Park (RMNP)

This is a great hike, but as with any wander-through-the-woods, this trail has its ups and downs. Here are some of the pro’s and con’s.

Pro’s:

This trail is located in Rocky Mountain National Park: If most of your backpacking has been two to three day excursions and you are looking to make the transition to longer trips with more time on the trail - this is the hike for you. The trail is well marked and well maintained, and even without a map, you might have to work at getting lost. Since it is in a NP (no hunting) the wildlife is used to us two-legged creature, and will, if left unharassed, allow you to watch them for as long as you like.

This trail is popular: While I love remote treks, I also like the company of other hikers, and this trail has plenty of that. You are likely to meet some interesting people on this loop, some of them even hiking the whole CDT which overlaps a long stretch of this trail.

Con’s:

This trail is located in Rocky Mountain National Park: I have a love/hate relationship with hiking in National Parks. While they are well maintained, they are also well regulated, requiring that you walk here and not there, sleep there and not here and so on. If I want to be told where I can and cannot walk/stand/sleep, I’ll check into a hotel. Having to reserve camping sites, carry a BearVault and get checked two or three times for each by a ranger tends to rub me the wrong way.

This trail is popular: This trail is so popular that it suffers (IMHO) from an excess of what I call the “Idiot Factor,” or IF, and the resulting IF-driven regulations. The IF is that small percentage of people who, wherever they go, just cannot keep their damn hands inside the ride, stay the hell away from the lip of the canyon or, in the case of RMNP, figure out how to sh*t in the woods and NOT feed the bears! As a result, the IF never fails to scare the jeepers out of the resident authorities, leading to an excess of knee-jerk regulations that must be suffered by the rest of us. In RMNP, the scenario has gone something like this:

“What this!” Some people cannot figure out how to dig a hole and bury their crap? Well, we’ll just have to require that everyone pack-out their toilet paper AND, coming soon, all human waste!”

“Whoa, hold on, hold on!” “Some hikers just gave their dinner to a bear!? Pass the regulations, and quick! Two to three pounds of useless, freak’n dead weight in the form of a BearVault must be carried by everyone!”

Concerning the requirement of a BearVault, I asked the nice ranger folks why they did not allow hikers to hang their food in bear bags, notably in PCT style. They responded that they tried that, but after some hikers pulled trees down on themselves (yes, I know, loud facepalm “smack!”), it was BearVaults for all.

And there you have it. All pro’s and con’s considered, should you hike this loop? Absolutely. Why? First and foremost, it is a beautiful hike. Second, and this could be true of many hikes, while the idiots, like the poor, will always be with us, this trail, with its stunning meadows, majestic wildlife and sweeping alpine pass, may not be.

Cheers,

JG

Great short hike with kids. We did the “walk back through time” program that was offered by the Visitor center and it was incredible. It was a 2 hour program that you have to sign up for in advance. It rained on us the whole time but it was still an amazing experience for the kids

The trail is quite wide and flat; very driveway-like. The trailhead is easy to access, and the pleasant walk through the meadow to get to the site was lovely. We saw an entire heard of elk huddled together to try to shelter from the rain.
Lovely.

The trail is a great family friendly trail that can be handled by most people. It is uphill on the way out but plenty of great spots to stop and catch your breath. As many other reviewers have mentioned this is perfect for spotting moose. We saw a cow and her calf only about a half mile into the trail. Our kids especially enjoyed it when the pair followed us up the trail for a while. Great hike with beautiful forest scenery at the beginning and the meadow at the end it perfect for lunch or snack before heading back.

Beautiful lake. Saw Moose , Elk and deer. Caught fish. Start early to plan plenty of time at lake and avoid afternoon rain. Can RMNP please cleanup landslide... would make for a spectacular hike if landslide was mitigated. It is 11 miles.

Great trail. A good cardio workout with elevation gain. Good trail to start out on as I just get into hiking. Whoo Hoo!

Nice, mostly level hike for most of it. Lots of downed trees-maybe not good for someone with bad knees. You have to go over or under a fair amount of logs. Trail gets pretty narrow at spots. Overall a nice hike with great views of SM Lake.

Our family of 15 includes 8 kids under 10. We loved this easy hike that included a nice waterfall 0.3 Miles in and a stream they waded in for 1/2 hour. We could’ve gone further but enjoyed the first stretch. It was perfect for our family.

Beautiful hike, even on a rainy day. Saw moose along the trail. It is a very steady uphill almost the entire way up but it make a nice return going down. There is a huge landslide around 2 miles in that required some scrambling around but otherwise trail is in excellent shape. We got 10.4 miles round trip.

Amazing trail! The elevation gain is no joke. Absolutely stunning.

This trail has yet to disappoint, in three times up this season there has always been a plethora of wildlife. As others have said just be mindful crossing the landslide area. I tried the alternate route once and it’s not really any better/easier and takes a bit longer. Also it is right about 5.2miles to the lake from the parking lot and if you go around you’ll end up covering 11-12mi.

My first trial ever and hike like this; i have to say it was beautiful and jumping/crossing the landslide was definitely an experience but it was well worth the long hike! I saw 3 bull Moose, Two female moose and a calf. I saw 2 huge Elk with nice set of antlers and a small deer! I highly recommend this trail!

Love this trail. Not too crowded. Saw only 1 other big group after us. Not too buggy by the lake. Very steady incline to the top which is very doable. No scrambling and no treacherous segments. Only a few fallen trees but easy to walk over. Nice view from the top even though the fire outlook is out of bounce. Saw the same deer twice which was really cute. Saw multiple ospreys and one nesting on top of a tree by the lake, which was amazing.

Tons of wildlife and multiple eco-systems. Water is readily available and camp sites (permit only) are very nice. Portions of the loop are very secluded. Wonderful waterfalls and plenty of day hikes if you want to stay extra nights.

The Falls were beautiful, easy hike up to the Falls. We then continued on for another mile or so, the meadows and river were really nice, with mountain views. We saw moose as well, so be on the lookout for them.

We picked this for our first RMNP hike as a way to get acclimatized to the 8500 ft elevation. It served its purpose. Relatively flat. Very popular hike. We saw a small crowd gathered watching 2 moose. There may be more wildlife if there were not as many people on the trail. The waterfall was nice. Refreshing to finally sit in the shade for lunch by the waterfall. Otherwise the path does not have much shade. Remember sunscreen, hat and sunglasses.
