Giants Trails Mountain Bike Network
The "Walpole Valley Mountain Bike trails" refer to the **Giants Trails**, a family-friendly network of purpose-built cross-country mountain bike trails in the Walpole-Nornalup National Park.
Developed by the Department of Biodiversity, Conservation and Attractions (DBCA) in collaboration with Common Ground Trails and Magic Dirt Trail Works, this network connects the town of Walpole, Nornalup, and the iconic Valley of the Giants Tree Top Walk.
It spans over 50 km in total (with an additional 70 km adventure cycle loop incorporating parts of the Munda Biddi Trail) and emphasizes low-impact, leisurely riding through ancient tingle forests. Some trails are graded **green (easy)**, making them suitable for beginners, families, and casual riders.
They feature flowing singletrack on firm terrain with gentle gradients, minimal elevation changes, and stunning scenery of towering red tingle trees, coastal inlets, and wildlife. The network opened in phases, with full access currently available in 2025.
Specific trail names are extensively detailed in public sources and the focus is on interconnected loops rather than standalone paths.
Below is a summary of the key MTB components based on available descriptions:
Trail/Loop | Length | Difficulty | Description
Short MTB Loops (Walpole/Nornalup Trailheads | 5–10 km (estimated per loop) | Green (Easy) | Beginner-friendly circular routes starting from sealed carparks in Walpole or Nornalup. These wind through open tingle woodlands with interpretive signs about local ecology, offering gentle climbs and descents. Ideal for half-day family rides, with picnic spots and views of the Nornalup Inlet. Connects to shared walk/cycle paths for hybrid outings. |
Medium MTB Loops (Valley of the Giants Access) | 10–20 km (estimated per loop) | Green (Easy) | Flowing trails linking the Valley of the Giants Tree Top Walk to nearby attractions like the Giant Tingle Tree and Hilltop Lookout. Riders pedal among 400-year-old red tingle groves, with boardwalk integrations and minimal roots for smooth pedaling. Features subtle elevation for a sense of adventure without technical challenges; great for combining with the Tree Top Walk (add 20–30 min).
Adventure Cycle Loop (Incorporating Munda Biddi) | 70 km (full loop) | Green (Easy) to Moderate | A longer, scenic circuit blending new Giants Trails with sections of the famous Munda Biddi Trail (meaning "path through the forest" in Noongar language). Starts/ends in Walpole, passing Monastery Landing, Sappers Bridge, and Frankland River edges before ascending gently to the Valley of the Giants. Suited for experienced casual riders seeking a full-day epic through karri and tingle forests, with opportunities to spot endemic birds and orchids. Multi-day options available with nearby camping.

Other MTB Options in the Area:
The broader Munda Biddi Trail (Map 8: Walpole to Denmark, ~154 km point-to-point) passes through the region and is MTB-suitable (easy to moderate), but it's more of a long-distance touring route than a dedicated network. For harder rides, consider extending to Denmark's coastal tracks.
Tips: Ride with a buddy, as phone reception is limited to 4G on the Telstra network. Trails are fragile—stick to paths to protect the ecosystem. Best ridden September–November for wildflowers.
