I started at the Lost Creek Ridge Trailhead, and followed the Lost Creek Ridge Trail up to Bingley Gap and followed the trail past the turnoff to Round Lake. Keep on following the trail, and once you are almost directly south and a little east of the tiny Sunup Lake, you will see a faint trail heading north. Follow that trail up to Sunup Lake, and from there you should see the summit of Breccia Peak. It's an easy class 2 scramble up to the ridgeline which will take you to the summit. It was around 6 miles and 4500 feet gain from the trailhead to summit Breccia. The views from the summit are pretty cool.
Once I summited Breccia Peak, I headed east down into the basin between Breccia Peak and Zi-iob Peak, which is a slightly harder class 2 scramble. Then I scrambled up to the Cell Tower/Radio Site on Zi-iob Peak, and then to the summit, and then connected back to the trail from Zi-iob (all easy class 2). The extra 1.5 miles and 500 feet gain to Zi-iob Peak are definitely worth it in my opinion. You could also go back to the trail, head east, and walk up an easy slope to summit Zi-iob Peak as well.
Took the trail back and ended with around 13 miles and 5000 feet gain. I really enjoyed summitting these two peaks because of the rugged area they are located, and the great views of the North Cascades and the entire Mountain Loop Highway area and Glacier Peak. The scrambling is nothing to be worried about, nothing will exceed class 2 unless you are trying to find a harder route.

The little lake in the first photo isn't located or named on Gaia GPS, so I don't know. I walked just by the left of it on my way over to Zi-iob from Breccia where I was standing when I took that photo.

Beautiful trip, but I wouldn't want to direct too much traffic towards what is essentially a cross-country zone without established trails. Breccia is an easy walk-up, but there are several places near the top where the boot path fades/disappears and you have to tip-toe through the fragile heather. The same goes for the area around Sunup Lake; there isn't really a "trail" around the shore. This fragile alpine basin won't withstand more regular use without significant damage to the vegetation.
