I always think one of the best parts of a trip is getting there! When it comes to getting to The Gardens, you have three choices - along the Avoca/Fingal road, up the coast road from the south or across the north east via Scottsdale and Weldborough Pass.
Weldborough Pass has one of the most amazing old myrtle forests, and you must stop and have a wander. The walk is short, fairly level and most people should be able to handle it without any problems. The reward is a cool, shaded meander amongst some seriously beautiful myrtle, ferns and fungi. If the image above is not enough, have a look at this Flickr site where it came from, for some excellent images.
The area was originally slated for rural development but the discovery of alluvial tin de-railed that. There was extensive tin mining nearby which attracted the largest Chinese community on any tin field in Australia. Their Joss House was donated to the Queen Victoria Museum in Launceston, on the condition it remain available for use.
If you do find yourself overwhelmed by the walk, the Weldborough Hotel is also nearby.
