Boulder/Nederland Map

Amazing gorgeous outstanding-wild raspberries at the start of the trail.

Solid hike for spring. Definitely bring micro spikes or yak tracks as the majority of the trail is covered in either ice or a few inches of snow. No need for snow shoes in my opinion.

Parking is pretty limited. We parked next to the entrance (it said violators would be towed), but didn’t have any issues. Others were parked in the area without problems as well.

Happy hiking!

This trail was spectacular. We parked at the Brainard lot because the road was closed. Three miles to the trailhead, but pretty and easy. Once we hit the trailhead we slapped on our snowshoes and were on our way. Nobody other than a cross country skier was out there. The trail wasn’t overly difficult but we felt the hills. We’re doing it again end of March. Beautiful trail for snowshoeing.

Trail was snow packed, footing was good with microspikes. Probably could have gotten away with just boots, but the extra traction was nice on the uphill climb.

Was an enjoyable hike; I’m sure it’s even better when the lake isn’t frozen.

Parking is kind of sketchy, but no problem finding a spot.

Hiked 3/8. Snow from the Moffat Tunnel mostly packed down first half. Lots of snow second half, recommend show shoes. We made it to the top without, with lots of post holing. About 2/3 into the hike, you come into an opening with 2-3 different paths, stay to the right, you will soon hike in between 2 sawed-off tree stumps, continue up hill through the small canyon to the lake! Amazing hike, beautiful trail! Ps Watch out for cross country skiers.

Lots of snow. Need microspikes and snowshoes. It is a great workout as it is steep.

This was a great hike. Took me about 3 hours 45 to the summit and 1 hour 15 to get back down. Crampons would have been great to get up that glacier. Had to stick to the rocks on the north side to get up which then caused me to miss the trail through the open space. Not a problem really though if you can identify the peak and cross. Was able to locate cairns to the top. The hardest part may have been getting back down the glacier without crampons. I basically skied down with my boots. The wind was a huge factor. Great hike overall.

Great trail for a relaxing ride. Constant view of city.

Super great! We got there early in the morning so there was plenty of snow. We saw a couple of people on the way but we mostly had the trail to ourselves. On the way down it had gotten quite packed down and there were lots of people.

Gorgeous winter hike. Tough with the extra mileage due to the road closure. Definitely bring snow shoes.

Awesome views and a lake. Did it today with a ton of snow on a windy day with snow bursts. Wasn't too bad, it was nice having the whole trail to ourselves! We did it without snowshoes (brought along spikes but didn't need them) and we were fine. There were a few spots where our feet sunk through the snow up to our knees, but walking a few feet out on the lake was cool.

Beautiful views of the high country, Boulder, and the foothills. Trail 98% dry on 3/4.

One of my favorite hikes of all time, but difficult to navigate due to snow unless you go in July or August. Absolutely gorgeous. The little lake at the top is quite a climb but worth it.

Spikes were sufficient until about a mile before the lakes

Gorgeous. You absolutely need snowshoes. The road to the trailhead is closed so tack in another 6 miles rt. Awesome trail. Nobody- other than us and a skier out there.

Great hike on a very cold morning. Couple of steep inclines along with the view will take your breathe away, both fugitively and literally. Then again first time on a steep incline on snow snowshoes, but I will do better next time. I'll also bring my pup next time... Go early, the crowds build quickly.

Did this hike today 2/28. Trail was packed down until about a half mile from the lake. You can use just boots, slick in some spots so I used micro spikes. The lake is completely covered in snow. You can snowboard down the majority of the way. Lots of tree cover.

Nice open space, wide path, views of the city.

Nice trail'; not very rocky, which explains all the runners. It was busy but not too crowded on a 70 degree Sunday in February. No ice at that time. When we got to the top of Sanitas, there were a TON of people and dogs!

No dogs allowed on this trail is probably what made it much less busy than the rest of the trails. We hardly saw anyone until the trail got to the top of Sanitas, then it was packed. Muddy and icy in some spots.

I hiked this on 2/15. The first 3/4 mike was on the road. The test was trail. It snowed all day an even though my tracks were covered in snow it was relatively easy to find the trail in the trees. The lake was nothing spectacular. Lots of flat white and wind. The trail however was really beautiful. Snow shoes made it easier but micro spikes would have worked.

Nice hike up to Mt Sanitas

Great for snow shoeing ! Had a great time on this very busy trail!

Snowed all morning, but no wind. It was awesome. Most of the trail is good enough to walk on with hiking boots, snowshoes would have been extremely helpful, skis would have also been nice. I have neither snowshoes or skis so I didnt make it to the lakes, started post holing every step about 3/4 mile to the lakes so I turned back. Hey it was worth a shot.

Beautiful valley hike. Clear path. Get there early this weekend, it’ll be full of trail runners.

Fun hike today 2/03, snowshoes not really needed as the trail is well travelled. The dirt road up is getting more challenging by the day, there was a stuck 4Runner and Xterra on the way out. Made it all the way to the creek crossing with a 4WD Honda Pilot and some momentum without getting stuck though, so it's still possible. Well worth the trip!

Very windy day, which wasn't too bad in the forest. The snow was pretty firmly packed on the trail. I used hiking boots most of the way without a problem, then switched to spikes about a mile - mile and half from the lakes, and then snowshoes for the last stretch. Unfortunately, the wind made hanging out by the lakes pretty miserable, so the trip was cut pretty short. Still gorgeous, though. Lots of skiers!

Completed 1/14, made it all the way up to the first lake with yaktrax/hiking boots. Last mile was definitely slow-going. Beautiful day, no wind. The trail was pretty obvious to follow.

Great Winter Hike when weather cooperates.

Early morning hike. Surprisingly, the trail was well traveled and easily followed unlike other times. Once making the turn from Rollins Pass, snowshoes are a must. Always a great hike and take the time on some of the steep climbs.

***Get there early as the parking lot was 1/3 full at 8:30 and was full at 11:30. About 75% of people were skiers.
