The Rockburn ( PURPLE ) loop is in my opinion the easiest section of the Avalon area. Once you have hiked up the Water Bars ( Ridge connector ) you will see the Rockburn sign. The entire loop is a well used and marked. Many bikers are always on this section but the trail is plenty wide. Its fairly level with small ups and downs. This loop would be idea for anyone just getting into hiking or mountain biking. There is no water crossings unless you hike part or all of the Hop The Snake trail ( Blue ). Part of my recording includes the New Ridge extension. It's not yet finished but much of it has been cut out already. What's not cut out has flags you can follow. I saw bikers on it today.
