Eight companies have now put in bids to develop 200 acres at the former Glyn Rhonwy quarry site in Llanberis.
Some Llanberis business people say they want a mixed development
One, Snowdonia Gateway, has already revised a snow dome plan and wants to develop a 500m covered ski run, with holiday and leisure facilities.
The other firm to have gone public, Beicio Llanberis Cyf, wants a mountain bike centre, cycle and walking trails.
Other firms' plans include a sculpture park, swimming school, industrial units and recycling of slate waste.
The council's Glyn Rhonwy working group will draw up a shortlist by June. No details have been released of the other companies involved.
Llanberis hotel owner Aneuryn Jones said local people wanted the site developed but were uncertain of the best way forward.
"I think people are scared that a development will be too big, we don't want another village there," he said.
GWYNEDD COUNCIL'S VISION
To create new quality and sustainable employment
To safeguard the culture and Welshness of the area
To safeguard the area's outstanding natural environment
"Its difficult to think what would be most suitable.
"The plan for a ski slope could work, but on a smaller scale than they have planned," he added.
Sandra Owen, who owns the Dolafon guest house on High Street, welcomed the development of the site.
"I think recycling slate waste is a good thing, but maybe not for Llanberis," she said.
"Of the other ideas I'd like to see a combination of things on the site which would appeal to as many people as possible," said Mrs Owen.
Development could have a major effect on Llanberis
"I'm for the ski slope because it could be used by the locals too, and children could learn to ski there. The swimming school idea sounds good too.
"We need to balance it as much as we can and put the place to good use," she added.
Gwynedd County Council has put together a Glyn Rhonwy working group which is now following a timetable to draw up a shortlist of developers by next month.
By October there should be an announcement about the preferred developers.
Sioned Williams, Gwynedd's head of economy and regeneration, said the council had also appointed specialist consultants to prepare independent assessments of the various bids.
The council has also drawn up its "vision" of expectations from development of the site, she said.
"The council's vision for the site is central to this programme in order to take advantage of opportunities arising from the unique qualities of Glyn Rhonwy," she added.
