After climbing Handies the day before, I decided to go for the Red Cloud / Sunshine loop in the clockwise direction. This whole bit assumes you're planning to try for both peaks from the Silver Creek TH. That's what I just did and on this day I learned 3 things that I think are worth sharing and I'll go so far as to call these - My Three Pieces of Advice:
First - don't be tempted by the loop. Yes, hiking back the way you came, not to mention with an additional 500 vert and a few extra miles, does not seem appealing. But what is even less appealing is descending loose boulder fields and scree for 2,000 vertical feet (especially after having summited two peaks!) Seriously - The hike on the standard Red Cloud peak trail is absolutely stunning. There is a short bit of rocks and scree at the top, but mostly it's just a huge green basin that is guarded by craggy 13ers and completely adorned with wild flowers. The Sunshine trail, on the other hand, is literally nothing but a ton of rock, with some sharp rocky bits thrown in for variety. This long painful down march is only briefly interrupted by a fun game of "Now Which Gully do I Slide Down Without Plummeting Off a Cliff." So yeah, going down Sunshine was not something I'd recommend.
Second - if you can't jive with advice number one, then I'd strongly recommend doing the loop in the counter clockwise direction. This is the opposite of what I did. Going up Sunshine from Silver Cree would surely give you a far better view of which gully to ascend and you get to enjoy those sharp rocky rocks on the way up with fresh feet and then when you're tired you get the nice long basin descent of Red Cloud.
Third - if you are the person that ignores advice 1 and 2, and/or you've already ascended Red Cloud but are now standing on the peak of Sunshine and someone talks you in to descending Sunshine (it is temping after all, "I can see the road right there" and people will try to convince you)....if this is you, then be very careful which gully you descend. Getting off the peak is easy, and you'll quickly find yourself in the flatish area deciding which way down and hoping like hell you don't get cliffed out. Here's the thing - if you didn't come up this route, once you get to the gullies, I can honestly say that it's hard to know which gully is the right one to descend. Especially because the WRONG one has the most cairns and the most worn in tracks so it therefore appears like the obvious best choice (wrong!). So please - Read up on the descriptions and most importantly, scout your options. Spend an extra few minutes walking back and forth and try to pick the gully that you can visually see each step all the way down. If you can't then there is a cliff (even if a small one)
Pro Tip - How to Know Which is the Right Gully? The one that looks like a ton of people have used, but also looks like a scree water slide into an hour glass, well that's the wrong one. That gully is doable (I just did it) but it's bad. It funnels into two class IV pitches which aren't long, only about 10 feet each, but on very bad rock. If you found this gully, then you need to go two gullies to the right!! If you do find yourself in that gully don't panic. The middle would end badly, but I descended the right side and found somewhat stable rock. I stayed right over the first class IV pitch and then crossed over to the left side (assuming you're looking down) for the last Class IV bit and found stable rock there too, albeit with gravel on the ledges that you have to sweep off with your feet. Fun! And all that was followed by a long "boot-ski" on loose gravel down to a 45 minute painful hike on loose sharp boulder field and scree. Ugh! (see advice number 1 above)
