To Do Map

Hello! Oh man.. where are my dog people to help a sistah out? This trail in its entirety is NOT DOG FRIENDLY. I hope All Trails can change to "some parts of the trail are accessible for dogs." I only saw one review with any robust mentioning of dogs and what you can't access here.

The Spring Loop goes north and south, and the south part of the loop does not allow dogs. There are several places in this area that do not allow dogs. I heard from another hiker that this was due to bears...but not sure what would stop them from moving to the other side. My friend and I had to do another part of the trail.. still pretty, but was an out and back instead of a loop. That was disappointing. The sign on the trailhead says no dogs on the south side and on one other part, but All Trails made me think we could do a loop by the above description. Not true! It says you will get fined, and yes, there were rangers out.

Here are the good parts:
FEE: $5 for non Boulder County residents
TERRAIN: Pretty smooth... a few gravelly areas, but mainly nice!
VIEWS: The lush fall colors were in effect. Pretty meadows and some forest areas.

Here are the bad parts (sorry bikers..)
BIKING: Tons of bikers! Beware. I wouldn't wear headphones. NO. Too many trail runners and bikers. At one point coming back down, we got stuck in a spot because there were so many bikers/runners that we tried to pull over for. Most were nice, but they DID NOT use bells of any sort to warn people. I was surprised I couldn't hear the bikers behind me until they were right up on us.

SINGLE FILE TRAIL IN SOME AREAS: some areas are wide open and so nice, but some parts are single file and hard to get off to the side for the fast-rushing bikers.

OVERALL: I was much happier as we moved on into the mountain...less peeps and just gorgeous fall colors. There is hardly any shade, so it is more of a fall hike. Tons of people and the issue with no dogs on the south made for a different hike than expected. I liked the North Loop part very much and liked down to the Fowler part of the trail. Very well marked. Beware though- lots of people and lots of bikers make for a bit of a "look behind your shoulder all the time" effect.

Pretty views but so rocky, and the large number of inconsiderate people riding bikes ruined it for me. I’ll try a hiking only trail next time.

Very relaxing

very nice trail just very crowded and parking costs 3.00 every two hours or so, starts all uphill then kinda eases towards the end

This trail is a very pretty, quiet walk around a beautiful lake. The day I went there were a lot of gnats. The trail was very dog friendly.

The lake is beautiful with lots of birds and great views as you walk around. Great for the family.

This is NOT A lightly trafficked trail. There were throngs of people. I suppose it’s nice if you’re a local, but I would not drive out of my way to come here again. If I hadn’t driven two and a half hours already, I’d have left when we had to drive away from the park and find side-street parking in a neighborhood.

Because it’s one of the few mountain bike trails, I avoid it and let them have it to themselves. Much better hiking trails about a mile into the Eldorado canyon.

Great park, but super busy almost all the time. Lots of geese and geese poop - frustrating walking a dog who loves to eat it! Be sure to stay in the pedestrian lane, bikers will let you know (not always nicely) if you're in the wrong lane.

Nice elevation-

I read a tip that sunrises were amazing here but sunsets were just as awesome. The sunset did not disappoint. I came with a dog I’m watching and she was much more excited than I was to enjoy the beauty of the lake. We arrived around 6:45pm knowing that sunset was at 7:30. The views were beautiful. There were a lot of people there and plenty with dogs of their own. It was still lovely to enjoy. We set out to walk the entire lake. I let Abby waddle into the water a bit. Golden retrievers are tough to keep out of water. So she got a little taste. She saw plenty of geese, ducks, and birds to keep her excited and wanting to barrow through the walk. We saw people fishing, jogging, cycling, strolling, picnicing, rowing and taking photos. At the end of the walk as dusk was transitioning to dark, it became windy and light rain came down. But we made it to the car just in time. 2.6 miles of flat paved east trail.

Nice easy walk for starters.

One of my favorite trails for trail running. Not super difficult but a nice workout. Pretty views!

Was a good easy hike to get some steps in. Ok views which is why I have it 3 stars.

All uphill, very crowded, pay for parking

Really nice walk around a very pretty park. The best part, if you like this sort of thing, was looking at all the amazing homes around the park! It was a beautiful morning!

This trailhead is easy yet beautiful and is super fun for the kiddos and my dogs love it there!

This is a beautiful area right by downtown Boulder. The hike is basically all up hill with the same view (albeit pretty). Even on a Friday morning, the trail was very crowded. However, once you reach the top of this trail you have so many other options to split off onto on trails, which is what we did. The other trails help to add some more distance, some varied views, and much less crowds. The trails all seem fairly easy to link back to one another and not get too lost.

Very pretty hike. Would have been 5 stars, but there are no benches.

Nice walk around the lake- beautiful views but quite busy.

Especially beautiful in the spring when it is green.

so close to home but definitely feels like another world. a few 'urban' features and more open patheways ...then if you head to the lake it is more natural and there are birds and turtles! love it.

We were here on the Tuesday after Memorial day and it was pretty busy. The path was paved, and is very scenic all along the trail. However, it is quite steep in the first ~0.3 miles, so I would say it's moderate instead of easy. Ranger recommends the meadow trail for easier path up.
Wild flowers in bloom right now are the bluebells and the dandelions.

I really enjoyed this leisurely walk along the creek. People & Dog friendly. Ample shade! Great bird watching!

I really enjoy this trail. It’s easy, breezy and sleazy.
