About the Company

At AVA, we specialize in creating unforgettable outdoor experiences in Colorado. In addition to world-class whitewater rafting on eight different rivers across Colorado, we also provide zip line tours at two locations, rock climbing, fly fishing, horseback riding, off-road tours, train rides, hot air balloon rides, cabins and camping.

Via Ferrata Course - Mt. Evans
from $149

At the base of a beautiful 14,000+ foot peak in the Colorado Rockies is one of AVA’s newer extreme adventures. Via Ferrata, which means “iron way” in Italian, is a method of mountaineering & rock climbing that’s been used in Europe for centuries. Via Ferrata courses use a combination of ladders, rungs, rails, cables and bridges to aid in moving across and up a cliff face. The Iron Way in Idaho Springs is an assisted rock climbing guided tour where you’ll clip into cables that run alongside a cliff. You’ll then move along a designated path of iron rungs and bridges. Along the way, you’ll be required to clip in and out of the cable to progress through the course. This is made possible through an advanced internal locking system in the carabiners. This system keeps you connected to the cable of the course at all times.

Hiking The East Inlet Trail

Close to the trailhead, it's a much lower grade. Throughout the valley, there are stunning views of the river, mountains, and lakes, but some of the best sights are seen if you travel past the maintained trail boundary to the end of the valley. Follow the river past Fourth Lake and then hang a right to get to Fifth Lake, the meltwater of which makes the river you've followed since the trailhead.

As the trail levels out you’ll pass a couple of small meadows. Keep an eye out for moose and elk foraging in these fields as you pass. Note that the edge of the meadow can be a bit marshy, especially in the spring. Only two-tenths of a mile up the trail are the remnants of an old homesteader’s cabin from the early 1900s.
