Rotorua
Rotorua sits on an active geothermal field in the central North Island...
Tauranga and its neighbour Mount Maunganui share a long white-sand surf beach and one of the sunniest, mildest climates in the country, which makes the area a popular summer and beach spot for New Zealanders themselves. It is the main town of the Bay of Plenty, a busy port, and a comfortable base for the kiwifruit country and coast around it.
The Mount, as locals call Mount Maunganui, is the focus: a sandy isthmus with surf on one side, calm harbour beach on the other, and the cone of Mauao rising at its tip. The base track loops around the cone in about 45 minutes, and the climb to the summit gives a wide view over the coast and the bay.
The beach, the base track and the climb up Mauao are all free, which keeps a beach day cheap once you are here. The Mount Hot Pools charge a small entry of around NZ$15. Surfboard and paddleboard hire is easy to find along the Mount strip in summer. Beach parking is free but limited, so on a hot weekend come early or expect to walk in from a few streets back. Sunscreen matters here: the sun is strong and the UV is high through the warmer months.
Honest note: the area is at its busiest and dearest over the New Zealand summer holidays from late December into January, when locals pack the beach and book out the motels. Outside those weeks it is calmer and cheaper, and the sun still tends to show up.
Tauranga and the Bay of Plenty get some of the most sunshine hours in the country, which is the area's main draw. Summer, December to March, is the prime beach season, warm and dry, often 23 to 27 degrees, with the surf, the swimming and the Mount at their best; this is also the busiest and most expensive stretch, especially the school-holiday weeks from late December. Autumn stays warm and settled well into April and is a quieter sweet spot. Winter is mild for New Zealand, often 9 to 16 degrees, sunny between fronts but too cool for the water for most people. Spring warms up steadily. For beach time, aim for November to April; for a calmer, cheaper visit with good odds of sun, the shoulder months work well.
Mount Maunganui's main strip, the beach and the base track are all walkable once you are there, and it is a pleasant area to potter around on foot or by bike. Tauranga's centre sits across the harbour bridge, so to move between the two, or out to Te Puke and the orchards, a car is the practical choice; the city is spread out and car-oriented. Bayhopper buses run on the Bee Card and link Tauranga, the Mount and Papamoa, though services are limited at night and on weekends. Parking near the beach fills up fast on summer days, so arrive early. Tauranga Airport is close in, about 3 kilometres from the Mount across the harbour, with domestic flights from Auckland, Wellington and Christchurch; many visitors also drive in, roughly two and a half to three hours from Auckland.
