7 Epic Ways to Spring Into Flagstaff This April
April in Flagstaff hits different. The snow is melting, the trails are waking up, and the whole town shifts into that sweet spring gear where every weekend feels like an invitation. Whether you're chasing adrenaline on a zipline, stargazing at a world-class dark sky festival, or road-tripping to a 50,000-year-old crater, there's no shortage of ways to make the most of the high country this month. Here are seven of our favorites.
1. Celebrate 25 Years of Dark Skies
Flagstaff was the world's first International Dark Sky City, and this year marks the 25th anniversary of that designation. The city is pulling out all the stops during International Dark Sky Week (April 13–20) with a lineup that turns the whole town into one big love letter to the cosmos. The flagship event, Starlight in the Square, takes over Heritage Square on April 18 with up to 30 telescopes, laser-guided constellation tours, local food vendors, and amber-lit ambiance after the streetlamps go dark.
Throughout the week, you'll find stargazing events at Dark Sky Brewing Co., Mother Road Brewing, Walker Observatory, and more — most of them completely free. If you've ever looked up at the Milky Way from Flagstaff, you already know why this town takes its stars seriously.
When: April 13–20, 2026 (Starlight in the Square: April 18, 7–10 PM)
Where: Heritage Square & venues across Flagstaff
Cost: Most events free (RSVP recommended for Starlight in the Square)

2. Fly Through the Pines at Flagstaff Extreme
Want your April to come with a side of adrenaline? Flagstaff Extreme at Fort Tuthill Park has 80+ obstacles and over 30 ziplines strung 15 to 80 feet up in the ponderosa pines — making it the largest zipline course in the western U.S. Choose the Adventure Course for rope swings, scramble walls, and wobbly bridges, or go straight for the zipline course and spend two hours flying between the treetops. There's a kids course too (ages 7–11), so the whole crew can get in on the action.
Spring is prime time here — the weather is comfortable, the forest smells incredible, and the summer crowds haven't arrived yet.
When: Open daily, 9 AM–5 PM
Where: Fort Tuthill County Park, 2446 Fort Tuthill Loop
Cost: ~$60 adults, ~$30 kids; group and senior discounts available

3. Dust Off the Mountain Bike
April is when Flagstaff's mountain bike scene comes back to life. The lower-elevation trails around Fort Tuthill and Campbell Mesa are typically snow-free by mid-month, and the Fort Tuthill Bike Park — with its jump lines, pump track, and flow trail — is free and open dawn to dusk. South-facing routes like Rocky Ridge, Pipeline, and Lower Oldham also tend to dry out early.
A word to the wise: higher-elevation trails on Mt. Elden and upper Schultz Creek may still hold snow and mud into late April. Check conditions before heading up — the Flagstaff Biking Organization has real-time trail reports. And if you want to race, the MBAA Flagstaff Frenzy XC race kicks off May 2 — just around the corner.
Where: Fort Tuthill Bike Park (free), Campbell Mesa, Lower Mt. Elden trails

4. Hike Into Spring
While the high-country trails above 9,000 feet are still buried in snowpack, Flagstaff's lower-elevation paths are shaking off winter and rolling out the welcome mat. Buffalo Park is the crowd favorite — a 2-mile loop with panoramic views of the San Francisco Peaks and wide-open meadows where early wildflowers start popping by late April. Fatman's Loop, which winds across an ancient lava flow at the base of Mt. Elden, brings golden zinnia, phlox, and Indian paintbrush as the days warm up.
For the full wildflower show, head south to the Sedona-area trails in Coconino National Forest (see #6 below), where the lower elevation means blooms arrive a month earlier. Back in Flagstaff, the real wildflower explosion hits June through August — but April is your sneak preview.
Where: Buffalo Park (N Gemini Rd), Fatman's Loop (Mt. Elden Trailhead), Campbell Mesa
Cost: Free

5. Get Wild at Bearizona
Just 30 minutes west on I-40, the town of Williams is home to Bearizona — a drive-through wildlife park where you cruise your own car through 3+ miles of ponderosa forest past black bears, wolves, bison, and bighorn sheep. After the drive (you can loop as many times as you want), park and walk through Fort Bearizona to see grizzlies, jaguars, otters, and more up close. April is a sweet spot for visiting — the spring weather keeps the animals active and the summer crowds at bay.
Pro tip: go on a weekday and save $5 per ticket.
When: Open daily, 9 AM–4 PM
Where: 1500 E Route 66, Williams, AZ (~30 min west of Flagstaff)
Cost: $30 adults (weekday) / $35 (weekend); kids 4–12: $20/$25; 3 & under free

6. Chase Red Rocks and Wildflowers in Sedona
April is arguably the best month to visit Sedona. The temperatures hover in the low 70s, wildflowers like California poppies and Indian paintbrush carpet the red rock trails, and the drive down through Oak Creek Canyon — named one of the most beautiful drives in America — is only 45 minutes from Flagstaff. Hike Cathedral Rock for a scramble with killer views (best at sunset), loop around Bell Rock for something more mellow, or trek out to Devil's Bridge, the largest natural sandstone arch in Sedona.
One heads-up: April is peak season, so trailhead parking fills fast. Start early or use the free Sedona Shuttle (Cathedral Rock trailhead is closed to private parking Thursday–Sunday). A Red Rock Pass ($5/day) is required for most trailhead parking.
Where: Sedona, AZ (~45 min south via scenic Highway 89A through Oak Creek Canyon)
Cost: Red Rock Pass: $5/day, $15/week, $20/year

7. Stand on the Edge of 50,000 Years
About 35 minutes east on I-40, a 150-foot-wide meteorite slammed into the Arizona desert 50,000 years ago and left a hole you have to see to believe. Meteor Crater is nearly a mile across and 550 feet deep — the best-preserved meteorite impact site on Earth. Walk the rim on a guided tour, catch the COLLISION! 4D theater experience, touch the 1,400-pound Holsinger Meteorite, and check out the Apollo 11 training capsule (NASA astronauts trained here before heading to the moon).
April is a great time to visit — it's warm at the crater's lower elevation but not yet summer-scorching. Budget about 1.5–3 hours for the full experience.
When: Open daily, 8 AM–5 PM
Where: I-40 Exit 233, Winslow, AZ (~35 min east of Flagstaff)
Cost: $29 adults, $27 seniors, $25 juniors 6–12, under 5 free
