To get to Sunday Gulch Trail you will need to walk around Sylvan Lake to the Northwest End of the Lake, there is a loop all the way around the lake, so either way will take you there. You will see a sign for Sunday Gulch Trail, it is trail #6. 

The trail itself can be quite steep in places but it does have hand railing for much of the steep downhill on boulders. There is a creek that flows along and even in the trail for about half of the hike. So in the summer be prepared to possibly get a little wet. There are countless waterfalls along the trail, most are small, but still beautiful!

The other half of the trail is away from the creek and but offers more open views as it traverses the hillside. The hike is a strenuous hike and a at least 2 hours should be planned to hike it at least. 

If you hike the trail in winter, do be cautious since the creek flows over the trial in places it can freeze and cause ice to build up so there is no good firm footing, good thing the hand rails are there!!
