Between Porto Istana and Olbia you can find the natural Park of Padrongianus where it’s possible to rent a mountain bike for a tour in the nature. You can also rent a Kayak for an interesting tour in the Padrongianus river. After sports, you can have a pic-nic in the gazebo area and relax in the middle of the nature. There is also a recreation ground where children can play safely. I would recommend also the guided tour starting from Padrongianus park to the Nuraghe Torra, where you can have a breathtaking view on Olbia’s Gulf. In the Padrongianus Park you can do a lot of activities as Nordic Walking, Orienteering, trekking, bird watching and archery.
