Picnic Point Park is another park featuring beautiful flower displays during the annual Carnival of Flowers (the others are Laurel Bank Park, Spring Bluff and Queens Park Gardens).
Here you will find playgrounds, BBQ and picnic facilities. There should be plenty of parking nearby. Go for a walk along one of the tracks, there's even one leading all the way up to Table Top Mountain (and yes, there's a cache up there as well). Or just enjoy a coffee or meal at the cafe and restaurant. Picnic point lookout is a must for every visitor, with its great lookouts over city and Lockyer Valley.
The following has been extracted from this site:
Picnic Point is one of Toowoomba's oldest recreation areas. Its origins can be traced to 1902 when Toowoomba City Council purchased six acres (2.42ha) of land for 120 pounds ($240). From those early days, citizens of the developing city took pleasure in visiting Picnic Point for the area's natural beauty. Over the years additional land was acquired, with the park now totalling 65 hectares. The stylish restaurant and café complex which overlooks the valley below is the fourth and largest such facility to be built on the same site, and is a testament to the park's popularity over the decades. From the lookout on the eastern edge of the park the Warrego Highway is visible as it winds its way down the range. It follows sections of the route used by early settlers of the Darling Downs to transport wool and other produce to the coast. Before the construction of the rail link to Brisbane in 1897, a steady stream of sulkies, coaches, horsemen, pedestrians, stock and bullock drays travelled along what was a steep and dangerous road. The name of the early route, Old Toll Bar Road, reflects that the government charged a sliding scale of fees for those using the route.
The cache should be an easy find - the difficulty will be to remain unseen, as the location is very exposed. You should be able to spot the cache from a distance.
