About

Tucked into the ponderosa pines at Fort Tuthill County Park just south of downtown Flagstaff, Flagstaff Extreme Adventure Course is a treetop obstacle and zip line park that draws families, teens, and thrill-seekers off the highway for a half-day of climbing, swinging, and flying through the forest canopy. It's rated 4.8 stars from over 1,600 Google reviews, and reviewers consistently point to the guides as the standout: attentive, safety-focused staff who walk first-timers through the gear before letting them loose on the course.

What to expect

The course mixes suspended bridges, ladders, and around 30 zip lines strung between the pines, with routes built for different comfort levels — reviewers with a fear of heights still describe finishing the course and calling it worth it. Plan for a real time commitment: guests who do the full course plus zip lines report spending 4-5 hours on site, longer with a big group. Groups can bottleneck at obstacles when a slower party is ahead, so arriving early or booking with a smaller party helps keep the pace moving.

Hours: daily, 9:00 AM - 5:00 PM
Location: Fort Tuthill County Park, 2446 Ft Tuthill Lp, Flagstaff
Good for: kids and adults, including nervous-about-heights first-timers

Book ahead, especially for school breaks and summer weekends, and expect to be in guided harnesses the whole time — this isn't a self-guided rope course.

We’ve been visiting for 5+ years and will return in the future! We’ve completed the adventure course a few times, and our kids had a great time on the kid course. We’ve brought kids and adults ranging from 5-40! The short training helps you feel safe and in control. The life guards (guides) are readily available to shout advice and encouragement when needed. This most recent visit, for my youngest’s 12 birthday, we did the zip line course for the first time and loved it! We had a party of 6 and it took us around 3 hours to complete. The zip course was great for one of our party who is only 7 months past a broken ankle. We love that we can bring our own coolers with snacks and drinks when we are ready for a rest and hydration break. It’s a bit of a hike before we start the course to place them at a good central location, but worth it. Great visit every time!

My 7 year old had a blast on the adventure course! It was so fun to watch his confidence unfold. All 3 guides we worked with were extremely helpful, calm, and patient. I think Adrian helped out my 3 older kids on the zipline course and they had a fantastic time. It’s now a memorable family vacation. All 4 of my kids mentioned FLGX as one of the highlights of our trip!

Our 4 teenagers loved this course! It was definitely a highlight of our vacation. Instructions and demo ensured everything was very safe. Our two oldest finished the whole course and it was super fun that they got the wrist bands and names on the board. A very fun time!

My teenage twins and I went there over their spring break (March 2026) from Tucson. It was the highlight of our trip! We would do it again in a heartbeat! Thank you Extreme Adventure staff!
