Places in the three huts are limited, but there are still spots available for smaller groups in all the campsites.
Numbers are similar to previous years, Hawkless said, but this year they are mainly New Zealanders.
Hawkless has catered for fewer walkers on the 3000km Te Araroa trail this year. Many of them take the option of canoeing the Whanganui River as part of the trail.
This year they are also mainly New Zealanders, and often they are doing parts of the trail rather than the whole thing. Hawkless estimates about 300 have passed through.
"Normally we do a lot more than that," she said.
Business has also been brisk at Whanganui River Adventures & Pipiriki Campground at Pipiriki, staff member Teresa Hohepa said.
The campground has been completely booked out on two occasions.
Most people are doing the Whanganui Journey, and others take jetboat trips upriver, with jetboat operators or in private jetboats.
The Bridge to Nowhere is a popular destination.
The river is pretty low at the moment, and very clean, Hohepa said.
