Leaving Christchurch via the "Great Alpine Highway", you'll cross the flat farmland of the Canterbury Plains towards the mountains. Halfway across the plains you will discover the small rural town of Darfield, where you will enjoy a short stop which will allow you to sample some of the local delicacies from the famous Darfield Bakery. Your next stop is Springfield, just 20 minutes down the road. Complete with its giant doughnut statue it's well worth a photo, and your guide will explain just how the town ended up with this giant doughnut. From Springfield the road winds its way up over Porters Pass at 900 meters, before continuing past Lake Lyndon and arriving at Castle Hill/Kura Tawhiti. This area is an amazing labyrinth of giant limestone boulders that sit in the Craigieburn Basin, surrounded by mountains. The area is rich with cultural and recreational significance and has a Tōpuni status of a "symbolic cloak of protection”. It is also known internationally as a world-class climbing, bouldering, photography, and film-making destination. Your guide will show you around and explain the geography and cultural significance of the area, before sitting you down for a picnic lunch. Following lunch you will have free time to explore the boulder fields in your own time, before meeting back at the car park at 2:00PM. From there, your return journey back to Christchurch takes approximately 1.5-2 hours.
