Beautiful hike. I definitely would recommend snowshoes and a gps. I lost the trail most of the time I was hiking from how much snow there was. Fantastic place to cross country ski! The parking lot is very difficult to drive to - plan on adding on an additional 1/2 mile to get to the trail head.

This is a pretty good trail that climbs steadily but not too steeply until you get to the saddle. It is mostly rocky though. At the saddle you pass Meadow Mountain and continue for a bit before hitting the park boundary. At the second park boundary, you go off the main trail and follow a faint trail initially marked by an arrow made of stones and then you follow this faint trail that is marked only by cairns and the park boundary markers until you get to the top of the mountain. There is a fair amount of tallus on the way up and also the climb gets steeper towards the top. It was windy and cold but not windy enough to stop me from making it to the top. The views once you reach the saddle and beyond are great but not much to see before that. I clocked this trail at 8.7 miles with a 3148 ft elevation gain. The round trip took me 5h and 21 min.

We only hiked as far as the saddle, about 3 mi. Some autumn color beginning and a few wildflowers remain. Quiet trail on a Monday! I have hiked to st Vrain mtn with my dog, on leash, but avoided Rmnp boundary. Please if you bring your dog pack out the poop bags.

Hiked on 9/11/19. GPS tracking had us at 9.7 miles - and it felt like that was correct. I’m not sure where a lot of the previous reviewers are from - I’m a Colorado native who hikes often for reference. I found the trail very enjoyable and never felt like a hard grade the entire length to the final ascent. It’s up, but it never felt difficult. The ascent up St Vrain is on the longer side, and the trail is difficult to find. It’s very easy to see where you need to go, so it kind of becomes “chose your own adventure” to the top. There’s a rock arrow next to some carins where the trail splits to go up St Vrain - but it’s EASY to miss!! Would definitely recommend. The views are fantastic once you hit the ridge line, and you overlook all of RMNP and the IPW from the summit.

This hike is a challenge from the beginning. But the views are worth it. The trail opens up after an hour. Once you make it to the pass you’re surrounded by unlimited summit options. While the trail is on the harder side, you don’t need to be an expert to do it. Just know that it’s going to be slow moving.

The mileage is accurate. The iPhone health app is not accurate. I confirmed with a GPS. Despite the review below, this was a good hike. Yes, the elevation gain is real, but it is that perfect balance where you can keep moving going up and it isn’t too painful coming down. If you flowers, hike in July, but there are still some along the trail. The views of the surrounding peaks are with the effort. Plus, the quiet solitude of minimal other hikers was a blessing!

Hiked both Saint Vrain and Meadow yesterday in a perfect weather. Hiked these separately 2 yrs ago. Was Labor day weekend noonish time, and was surprised not to see any one on the way up or down from the mts. Have seen hikers at the saddle. Trail finding to Saint Vrain wasn't easy and no trail exists to Meadow Mt, but easy to eye ball the peak through the rough rocky terrain. I would definitely hike these 2 again.

Awesome trail. Plenty of quiet time to myself, but still a few people once in a while to not be completely alone. Just going up to the area where the trail becomes flat, right above the tree line, is almost as nice and not quite as hard. You get to enjoy a beautiful view in two directions. To get to the very top, you have to go off the path and scramble straight up the mountain, which is by far the hardest part of the trail, so safe your energy for the end! But the 360 degree view is breathtaking and worth it, so keep pushing!

Note to casual hikers - this trail is relentlessly steep, extremely rocky, and monotonous, with no vistas until the end. There are no wildflowers to speak of, and you are only by the stream for a few minutes. The RT Apple health app. Is close to 12 miles including switchbacks, zigs and zags, and what seems like miles on a rocky beach, dodging rocks. Others must have already figured this out, since I only saw 13 people all day on an August weekend with great weather. The payoff, of course, is the absolutely magnificent view from the summit of Longs Peak, Wild Basin, and the Indian Peaks Wilderness area.

*Pro tip. Did this on a Saturday in the summer and the trailhead parking lot fills up by 7:45am. You'll also want AWD or 4WD cause the final mile is on a bumpy gravel road. Few people did it in cars but I feel bad for their suspension. Whoever says this hike is 'unremarkable' must be climbing some incredible mountains every single day cause I loved this hike. It's a beautiful trail which takes you through a forest to start then along a mountain creek and finally you crest over a saddle where you get the view of St. Vrain Mountain. Did this today (8/3/19) with my girlfriend and we got lucky with stellar weather--no wind and all sun. We hit the summit round 11am then made our way over to the far side of the summit to enjoy the 360 views. It was a challenging hike at the end as you scramble to the peak but any experienced hiker could do it. To actually summit St. Vrain Mountain you need to divert yourself off the marked trail and 'choose your own adventure' to the top. There are some boundary poles for Rocky Mountain National Park that you can follow which help but really you can't get lost. Just keep going up! It took us 5.5 hours round trip. Have fun!

Beautiful hike!! A little tricky driving the last mile or so, if in a smaller car. The start of the hike is forested and takes you along a creek. A few miles in it starts to open up to some views. Right near the small stint in RMNP is GORGEOUS (clear view of Longs Peak)! Only a short section of trail was still covered in snow, but very manageable (on 7/20). The trail kind of ends before needing to make a sharp right to ascend the peak (there’s a false summit near the top). Definitely worth the rocky scramble for amazing 360 views! Round trip was about 8.5 miles for us.

Views at the top are nice but otherwise the hike was unremarkable. Very rocky. Still a little bit of snow towards the top, but manageable. Best part of the hike was watching clouds form around the peak of Longs.

Nice trail. With the exception of the east face of the peak all of the snow is gone. Did see a large Bull Moose in the middle of the trail coming out.

Made it all the way up to the foot of St. Vrain Mountain but couldn't summit due to snow. I'm going to try again this Saturday (two weeks later). I'm expecting the snow to be mostly gone. It's an awesome hike- Saw a moose and there's great views of the Indian Peaks above the treeline. Road to the trailhead is a bit rough but doable in a car.

Unfortunately I didn't make it to the top because of the snow (around mile 2), but I absolutely loved this trail! Lots of shade, great views, and a few creeks on the way. The incline starts of very mild then gets steeper as you go, however, the section of the trail I did wasn't too difficult. Also, the road up to the trail is fairly rough so be weary of that!
