Ketchum, Idaho (KMVT-TV) Talks are underway in Sun Valley to build a series of new mountain biking trails.

The elaborate trail system would offer new outdoor opportunities to people of all ages.

The Sun Valley Resort wants to add one more activity to its list of outdoor adventures.

"What we've proposed here is a series of mountain bike trails," said Peter Stearns, Sun Valley Resort.

The over 17 mile mountain bike trail system would be constructed on Baldy over the next several years.

Part of what makes it unique, is its accessibility.

"The gondola is a key component in it. There's opportunities for families to where certain members who don't want to ride can go up the gondola and have lunch, other family members could ride on the trail and meet up and have lunch together," said Stearns.

Each bike trail will have signage depicting direction and difficulty. The rating system will be similar to what you'd find on a ski mountain.

"Near the top end there's some beginner trails that are similar in characteristic, but may have a lesser slope gradient, intermediate type trails, and then you'd have more technical trails both to climb and descend," said Stearns.

But, before the building process can begin it must first be approved by the Bureau of Land Management and the U.S. Forest Service.

"We'd be looking at the resource impacts, public comments, impacts to other users to the environment and then make a decision," said Kurt Nelson, U.S. Forest Service.

Trails exist on the mountain already, but mostly around the perimeter.

Right now the level of difficulty ranges from moderate to advanced.

But, the new system will consist of flow trails that create a fun ride for all skill levels.

"It's kind of like a rollercoaster on the side of the mountain. Or, a summer ski experience on the side of a mountain," said Nelson.

These trails are expected to roll out over the next five years.
