no other trail directly connects, but there are a couple other near by on gravel roads, not near as technical or fun. there is a fire look out tower a few miles up the gravel road that has amazing views, as high as any where you can drive in the Oregon cascades.
here are some pictures from champion creek, it the same area, the trail we went up is called the noonday trail, more of a jeep trail then a real dirt bike trail. also a very old trail from the old miners looking for gold.

There also are quite few nice hiking trails with short hikes in to little water falls near by.
