Springtime in Aspen is time to kick up our heels! With plentiful snow & sunshine, it's a sensational time for enjoying winter & summer sports, including ridge top snowshoeing, hiking & biking.

As Aspen's longest running originally owned adventure sports company since '96, our almost 3 decades of teaching & guiding experience will will directly & positively affect your adventure experience. As pioneers, we offer NEW one of a kind adventures each season; another reason for our exceptional longevity.
We're open year round, as there's always outdoor fun to be enjoyed in Aspen! We're not part time lovers, like others.
Your private individual or group adventure will not be a "cookie cutter" public Aspen tour or group nature tour with a minimally experienced guide. We want your adventure to be very special, customizing every aspect of YOUR recreational adventure, while providing the high level of care you deserve.
We'll even bake you Erik's Organic Chocolate chunk cookies, which are internationally renowned!
Minimize risk & maximize your valuable time in Aspen or Snowmass snowshoeing, cross country skiing, fat biking, mountain biking, road biking, e-biking, hiking & flatwater canoeing with the area's most experienced & versatile guides & instructors. You'll be professionally guided in the best areas for your abilities and goals, while gaining skills. New skills lead to new thrills, without those pesky spills, making you safer, performing better & therefore, having more FUN.
Self-guiding does not maximize skills, performance & fun, leading to compromised experiences & hundreds of visitors ill prepared, lost & injured, creating record mountain rescues in the Aspen area each year. Know before you go or hire a pro, whose #1 focus & priority is your safety. There is no substitute for experience & knowledge in the mountains, where the risk can be as high as our peaks.
April '25 UPDATE:
Our non-mellow yellow Lab & Sun Dog mascot Marley just turned two years young & would love to hike with you! Like us, our energetic girl lives to share what she loves.
If that wasn't awesome enough, two feet of snowfall blanketed our favorite ridge top snowshoeing spot this past week, making for sweet springtime base layer & baseball hat snowshoeing. Guests who've snowshoed around the globe, often call it "world class snowshoeing" as this route offers abundant snow, mind blowing views, rolling terrain in & out of the high alpine forest & option for lunch in the Sundeck Restaurant or patio atop Aspen Mt. to follow.
Crossing into summer sports, we're also offering you hiking & biking, especially enjoyable on our beautiful paths & low traffic roads on warmer sunshiny days.
Want to celebrate Spring Break in style? Our one of a kind Champagne Snowshoeing Adventure TM has been a big hit this season & includes a Veuve Clicquot toast accompanied by Paradise Bakery croissants, topping off world class ridge top snowshoeing. Cheers to great times with family & friends!

Adventure in Aspen & Snowmass with the original Sun Dogs.
OUR STORY:
After a dozen years of racing & establishing our adventure sports school to share what we'd learned & loved, there was no manual on how to teach mountain biking in the mid-90s. We literally had to write it, as we developed and refined our teaching methodology, saving our guests years of time & effort as compared to "The School of Trial & Error" or "School of Hard Knocks." OUCH! No need for all that pain & wasted time.
With a lot of passion, hard work & a bit of traction & success, we added long time local athletes & instructors and pioneered NEW exhilirating adventure sports programs, most recently one of a kind adventures like on snow FAT BIKING & flat water canoeing in our nature preserve. Your time is Aspen is precious. Maximize your time, while gaining NEW SKILLS with some of the most experienced cycling & adventure sports instructors in America offering you 100% guest satisfaction & rare 100% clean safety record.
It's a compliment the copy cats would follow. But, when you're not the lead dog, the view's always the same! It's all about having fun, with safety #1, for YOU as our guest.
