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.


Via Ferrata Course-Granite
from $149

Come venture along AVA’s NEW Granite Via Ferrata course in Buena Vista! You’ll take two ziplines to the starting point of this adventure, then traverse high above the Arkansas River Valley along the granite cliffside. This course is a more exposed, edgier rendition of AVA’s Mount Evans Via Ferrata in Idaho Springs. Rappel down a rock face, ascend crags, cross multiple suspended bridges, and try out a 65-foot free fall on the Granite Via Ferrata. The 3-hour excursion is built at the base of the 14,000+ foot Collegiate Peaks and will have your heart pumping as you scale the mountaintops of the beautiful Colorado Rockies.


Hiking The East Inlet Trail
from $90

The trail begins at a peaceful waterfall and climbs steadily up through the valley. A great intro to backpacking or a lovely trek on its own, the hike also has a few steep parts. 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. You can go as far as you want on this awesome out-and-back hike!

Star Light and Full Moon Zip Lining -Idaho Springs
from $109

Join AVA for one of the most exciting and popular Colorado mountain summer adventures – ziplining! The Starlight Zipline Adventure is exactly what it sounds like – AVA’s Cliffside zipline course after dark. Meet our guides at the Idaho Springs office just 30 minutes outside of Denver. They’ll give you all the instructions in the light but the trip really gets exciting once the sun goes down. We’ll use glowsticks and headlamps to supplement the stars and moon. Our Starlight Zipline Adventure is an ideal way to experience the beauty of the Rockies at night. You’ll find big mountain views for miles, a beautiful short hike, and exciting drops with zooming lines through the treetops.


Hiking The Green Mountain / Onahu Creek Loop
from $90

From the parking area the Green Mountain Trail climbs through a lush conifer forest. The climb is steady and moderate, but graduates to more gentle grades after the first half-mile, with a few brief steeper inclines every now and then. 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. After viewing the meadows, head back to the main trail and turn right to begin heading northbound on the Tonahutu Creek Trail. From the junction the trail skirts around the western edges of the meadow. The trail offers several additional vantage points, as well as access to the meadow. The Onahu Creek Trail takes you past several small open meadows as it doubles back to Trail Ridge Road. This provides you additional opportunities for spotting moose and elk.


Cliff Side Zip Lining Half Day-Idaho Springs
from $109

Voted the Best Zipline Tour in the Rockies last year, the Cliffside Zipline in Idaho Springs is just 30 minutes from Denver or 1 hour from Summit County, Boulder or Winter Park. You’ll find big mountain views for miles, a beautiful short hike, and exciting drops with zooming lines through the treetops. You’ll start at our Idaho Springs Outpost, where you’ll check in, receive your zipline gear and get the zipline safety rundown. We’ll then drive you most of the way up the mountainside of our 9-acre property. You’ll get to the very top with a 10-minute hike to platform #1. All of our platforms – #1 through #6 – are built into natural cliffs and treetops.
