Tips

Two enormous bald summit 46ers and a trailess Gray Peak in a day loop hike form Heart Lake. A state highpoint as well. This is an epic hike that will gain you three more Adirondack 46er peaks along with the State Highpoint, Mt. Marcy. Make sure to follow the GPS track and pay attention to the trail junctions as there a few. You'll pass by alpine lakes, the start of the mighty Hudson River, and descend the state highpoint past a beautiful waterfall. This hike can be done in one very long day or in an overnight with a stay at Marcy Dam where the loop hike begins. Parking is $12 per day

Heart Lake Adirondack Loj Trailhead: From Exit 30 take Route 73 towards Lake Placid for 26.5 miles. Take a left onto Adirondack Loj Road and continue 5 miles to the Loj and the parking area. There is a $10 per day fee to park here.

Did this hike about a month ago and it was pretty incredible! For sure a long day but worth it. We had great weather and not much wind at the summits. Skylight definitely had my favorite views. At the time we went the parking lot at the loj was filling up around 7am which is crazy! The hike took us about 10.5 hours. Legs were tired at the end but a great day none the less!

8/6- Verrrry wet! Floaty logs along the base of mt colden; supposedly there is a bushwack off to the left to avoid them. I went over/through and the water went halfway up to my knees!

great hike. Skylight had incredible views. needed these 2 on the quest for 46. As most went for Marcy, had the trail mostly to myself until almost at Gray. LOJ filling up at 5:30am on weekends. I was on trail from 6am to about 4:30, but I am over 50 with both hip replaced. Sun was hot and beautiful at the same time. I used filtration system 3 times to fill up 3 litre bag over the entire hike, plus I had a frozen Pepsi Max that was perfect temp on top of skylight. Steady climb and lots of water to hydrate, still should have had more! Bogs not bad, has been dry.

Did this hike on 7/24/2020. Gorgeous weather, no wind, clear views on all 3 peaks. Lots on mud on the backside of Marcy and down to Marcy Dam. Skylight is by far my favorite peak so far!!

Did this route heading up the Lake Arnold trail from Marcy damn to hit Gray, Skylight, then Marcy on 4th of July. Hiked into Marcy damn the night before to wake up on the trail. Started at 5:30AM and was back to the car by 6:00PM. As mentioned before keep an eye out for Lake Arnold it’s a great breakfast rest stop. Also watch your step on the “bog bridges” soon after this point! If you need water I suggest filtering before you head up Gray as it’s the last big water source until the other side of Marcy. Took a nice long lunch break on Skylight this view was incredible!!!! Took another break on the top of Marcy after a short but very steep hike up the back side. Rested up before heading down the front of Marcy towards the Van Hovenburg trail, taking another break at Indian Falls to soak our feet and filter some more water. Smooth sailing back to the dam after this break and ended this long day with some much deserved ice cream!! Amazing time!

Overall it was a great hike on 7/7/20. Ended up being about 19.6 miles around the loop compared to the 17.6 that is posted. Gray was challenging, but the most challenging part seemed to be the long trek back to the Loj over the rocky trail, and the boards that sank into the water. It was a challenging, but rewarding day. If you plan on going during a clear and sunny day, prepare to bring extra water, as the sun was pretty strong. Enjoy!

Gray is the toughest — I started with Gray and ended with Marcy. The walk back from March to the loj is brutal! Felt like foreverrrr.

Great and long day out in the ADKs! Added The Phelps and Tabletop to this loop for a 22.5 mile loop with over 7000ft vert. The main trail to Marcy is great and the busiest section. Trail fo Phelps is steep but with very rewarding views. Tabletop’s herd path is very easy to follow. Limited views at the wooded summit. Marcy is huge and of course has gorgeous views. Very slabby. Went up and over to continue down towards Skylight which was my favorite summit of the day. Beautiful views. Gray Peak’s bushwhack was tough. A lot of steep climbs up and over boulders and slides. Go past the summit to find the sign. The hike out back to the Loj is long. The worst part is having to go up about 400 feet over a pass of sorts. Seemed horrible after already having so much vert for the day. The last 4 miles to Marcy Dam and the Loj take forever but at least they’re flat and not very rocky so you can cruise if your feet and mind allow it.

This is an epic day hike with extraordinary views from the summits of Marcy, Skylight, and Gray. Had good weather, minimal bugs, was a little muddy but not too bad.

This triad can be done as shown on the included map from the Loj: Marcy, Skylight and Gary. Or you can take the Lake Arnold trail and do Gary, Skylight and Marcy. Another option is: Marcy, Gray, Skylight and back over Marcy. I’ve done these three routes, and have found the Marcy, Gray, Skylight and Marcy trek the most interesting and enjoyable. No matter what way you do these three, it’s a tough day. The routes are easy to follow. All three peaks have amazing views, even Gray which people often overlook. Skylight is beautiful, and one of my favorites. Water sources are Indian Falls, Lake Tear, or the Opalescent. Enjoy!
