Waikato River

New Zealand's longest river (at 425km) is aloof and prickly, with hidden depths and periods of stormy moodiness. While often picturesque and inviting (especially during the scorching summer months), the Waikato River is more practical than personal. Once an important transport route for Māori, the waters are still popular with boaties, especially the sheltered waters of Karapiro. There are nine hydro-electric power stations and eight dams, which generate approximately 13% of the nation's power; and its banks are becoming an important tourist attraction, especially for cyclists.

That being said, there are still lovely swimming holes and quiet river trails to be found – off the beaten track. Here are a few to look for:

The Cambridge Heritage Walk covers both the Settlers Track and the Soldiers Track. Starting from Bath Street on the town side, the route follows the river down to Fergusson bridge, then back to up to the bridge on Victoria Street. This walk passes many historic sights and has good views of the river and town. For a heart-stopping view and an excellent view of a working power station, gather your wits and tip-toe on to the Arapuni Suspension Bridge. The 152m bridge was built in the 1920s to give workers access to the power station and is now part of the

Waikato River Trail. Park off Arapuni Road, the bridge is well signposted.

Waipuke Park on Lake Karapiro has safe swimming, a playground and picnic spots – the perfect place to watch an afternoon drift away. There's always some action to entertain on the lake as well – whether rowing, waterskiing or other water sports. Signposted from Maungatautari Road.

Some sections of the local cycleways are suitable for walkers, including the Te Awa Trail. Walk from the Avantidrome to Cambridge town centre (3.2km, including a section along the river) and from Cambridge to Karapiro (8km). The walkway is wide and generally flat, but do watch for cyclists, and vice versa.
