Trail shared by Chris Wandervans

Amazing views with a near endless downhill.

Snowbound until July.


One of the best downhills in the Stanley area. The initial climb is steep in sections, but it's worth it for the long downhill. Lots of amazing views on the way down.

Need to Know

You can either shuttle this ride or finish it up with some road riding.


Start with a climb up Boundary Creek. The trail is a steep climb that will see you off your bike in some sections, but is overall climbable by most people. This ride starts with many switchbacks and can get loose during the end of the season. Settle in for the long climb and stop along the way to catch your breath and take in the views. This climb starts in heavy trees and then becomes more open as you get towards the top, so it's best climbed in the morning during the hot summer months.

Once at the pass, you'll turn left onto the Sunny Gulch Trail which has a little more climbing before you begin your descent. The first part of the descent is down an open ridge line with some great views of the Sawtooth Mountains. Soon thereafter, you'll enter into some heavy tree cover as the descent continues. Finally Sunny Gulch Trail turns into Little Casino. The majority of the traffic goes down Little Casino and most people blow right by the trail junction without even noticing.

Little Casino is very moderately graded 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 a little drier. 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'll 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. Little Casino 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!

Trail was in very bad condition, lots of downed trees and very loose rock made for more of a hike-a-bike then downhill.
