It is the holy grail of New Zealand tourism: easing the path to Milford Sound for domestic and international tourists without destroying what lures them there in the first place - its scenery, ecological value and remoteness.
For decades, tourism entrepreneurs have laid schemes at the door of the Conservation Department without quite prising it open, from a coastal road defying engineering conventions to a gondola.
Now, DoC has allowed two proposals a foot in the door - one a bus-only tunnel with approach roads through two national parks; the other a "back-country experience" involving boat, 4WD bus and monorail. Both promise to cut in half the circuitous 4hr road journey from Queenstown to Milford around Lakes Wakatipu and Te Anau. The applicants plan international marketing to bring an estimated 20,000 extra visitors a year to New Zealand, targeting time-poor tourists who want the greatest hits at speed.
What's the rush? Accommodation at Milford is strictly limited. Though Te Anau, two hours' drive away, can accommodate 4000, most visitors to the region opt to stay in the bright lights of Queenstown. Up to 40 buses daily ply the road route, giving visitors a three or four-hour window in Milford - time enough to have lunch, cruise the fiord and maybe visit the observatory- before the ride back.
