Enjoy a trip to the city of Ponta Grossa (about 100 km from Curitiba), where you'll visit Vila Velha State Park, the main natural attraction of the region. Admire the impressive sandstone formations, the large craters, and the exuberant vegetation and groundwater. Discover the Lagoa Dourada (Golden Pond), which gets its name from its glinting golden waters from the reflection of the sunset. Other great attractions of the Park are the Furnas, very large craters, one of them with up to 100m depth with half of it covered by water and surrounded by beautiful greenery.
