This trail can be completed in any number of combinations as an out-and-back or a bigger loop. You can climb Big Casino and Sunny Gulch
and then descend to Little Casino or you can climb Boundary Creek
and then descend Sunny Gulch
to Little Casino. This trail and the downhill on Sunny Gulch
trail are one of the best long downhills in the Stanley area.
The trail is a very moderate grade the entire way, so it makes for a nice long downhill. There has been a lot of work done recently to reduce stream crossings so your feet will stay dry a little better. At the top of the trail you'll go through a number of meadows and this is where you need to be very careful with watching which way the trail goes since people constantly make wrong turns and then lead others astray.
If you end up in some tall grass, you might want to back track to make sure you did not miss a turn. The trail skirts a number of meadows, so you get some great views and may spot some wildlife. About half way down you'll enter into thicker timber and leave a lot of the meadows. Eventually, the trail will follow the creek the rest of the way down. The trail is very smooth in sections with some quick ups, but watch out for the root sections. There are definitely some root and rock sections that can send you flying!
