Wonderland is a journey through the heart of the Walpole Wilderness and an alternative to the Munda Biddi Trail between the Tree Top Walk and Sappers Bridge. This single direction trail flows from east to west but not down any rabbit holes. This is a long, mostly descending trail winding through massive tingle forest towards Kwakoorillup Beela (Frankland River). You can return along the Munda Biddi Trail making for a spectacular loop option. 

To complete the 30km loop from the Giants Trailhead, follow the Glass Slipper towards the Tree Top Walk before turning right onto Gatekeepers. Then take the Munda Biddi Trail (west bound) until you hit Wonderland junction. Wonderland takes you almost to Sappers Bridge where you can return to the Giants Trailhead along the Munda Biddi Trail (east bound).

If a challenge is what you're after, you can make this a full day, 82km loop which incorporates Walpole and the trails at the western end of this trail network.
