Need-to-Know Numbers
Mark three Fridays—March 28, April 4, and April 11, 2025—because those are the only nights the Watershed Nature Center opens its boardwalk after dark. Check-in starts at 7:30 p.m., the chorus winds down around 9:00 p.m., and the whole 90-minute adventure costs a single latte: $5. Group size caps at twenty people aged seven and up, so procrastinators stay home with the crickets. Reservations run through the Nature Preserve Foundation, and the quickest way to claim a spot is the online form linked on the official Frog Walk details page.
The nonprofit hosts these walks to show off a wetland it rescued from an old sewage lagoon back in 1991. Thanks to decades of restoration by the Nature Preserve Foundation, the 40-acre marsh now pulses with leopard frogs, chorus frogs, and the occasional tiger salamander prowling the water’s edge. Your ticket fee circles right back into habitat work, so every croak you hear helps fund the next generation.
Why Frogs Sing Louder Than Sound Machines
Early spring in Colorado’s high country is mating season, and for amphibians that means an all-out vocal throw-down. Male chorus frogs strum their throats like tiny banjos while the bigger western toads add a rolling trill, each call staking territory and wooing females. Warm dusk air after a rainstorm turbo-charges the show; guides report the loudest peaks when evening temps hover near 50 °F and the first soft showers tap the cattails.
Humans get bonus perks. A new-moon sky often blankets the marsh during these dates, so when the red-light headlamps click off for the finale, you’re treated to Milky Way glitter above the rippling calls below. Couples slip in hand-in-hand for a crowd-free date, kids stand slack-jawed as green lasers of aurora-watch apps trace constellations, and naturalists log audio clips for citizen-science databases. Sleep-noise playlists just can’t compete.
From Cabin Door to Marsh Shore
Set a 6:45 p.m. alarm at Junction West Vallecito Resort. That gives you wiggle room for the 20-minute drive south on County Road 501, a westward jog onto US-160, and a final turn guided by Bayfield’s brown “Nature Center” signs. Cellular bars waver in the forested canyons, so download an offline map or print directions before rolling out.
Parking is tight—another reason to pin a quick ride-share note on the resort’s bulletin board by lunchtime. Arrive around 7:15 p.m., drop $5 cash or card at the welcome table, and hit the restrooms because they lock once the walk begins. After that, it’s boardwalk-only terrain; no need for trekking poles, but rubber-soled footwear keeps you upright on occasionally slick planks.
Dress Quiet, Walk Light
Mountain nights near 8,000 feet plunge into the 40s, so layer up with fleece that doesn’t swish. A rain shell is smart insurance against those frog-loving drizzles, and waterproof hikers or rubber boots fend off damp boards and puddles. Guides hand out red-lens headlamps, yet bringing your own frees batteries for others and keeps the group glow gentle on amphibian eyes.
Comfort items matter, especially for grandparents: a collapsible camp stool or small towel turns listening pauses into relaxing sit-downs. Spritz insect repellent back at the resort, not at the marsh, to avoid chemical overspray. Before you leave, dip shoe soles in a mild bleach solution—one twenty-second dunk reduces the risk of spreading chytrid fungus that threatens frogs worldwide.
What Happens on the Boardwalk
The program opens inside a tiny classroom where naturalists show replica skulls and frog call recordings, priming young brains and curious adults for the live performance ahead. By 7:45 p.m., everyone files onto the ¾-mile loop, pausing every few yards so ears, not feet, lead the way. Expect a quick briefing on marsh etiquette—stay on the boards, whisper, and let amphibians set the tempo.
Guides cue you to each species: the “whirr” of the Colorado River toad, the metallic strum of the boreal chorus frog, the basslike grunt of the bullfrog lurking deeper in the reeds. Volunteers encourage participants to log calls with the HerpMapper app, turning the outing into real-time science. The finale comes at 8:55 p.m. when lights blink off, chatter drops to silence, and the marsh soundtrack swells under a dome of starlight—prime time for that whispered proposal or long-exposure photo.
No Ticket? No Problem—DIY Frog Listening
If dates sell out, don’t abandon hope. Quiet shoreline pullouts along the east side of nearby Vallecito Lake often host their own amphibian opera. Choose a turnout at least 200 feet from private cabins, arrive on a calm, 50 °F night, and stand motionless for two minutes; the marsh hushes at first, then picks back up once frogs trust your stillness.
Field-guide apps work offline if you download data in advance, and a basic voice recorder captures calls for later ID. Keep flashlight beams angled downward, stay on existing paths, leash pets, and pack out every crumb—Leave No Trace ethics ensure the chorus repeats for the next adventurer.

Build a Day Around the Ribbits
Spring afternoons shine for birding on the Lake Eileen or North Canyon trails, both within a 15-minute drive from the resort. Spot western tanagers over lunch, rinse muddy boots at Junction West’s laundry rooms, and still have time for a sunset paddle—kayaks and SUPs rent onsite—before heading to the marsh. Resort quiet hours (10 p.m.–7 a.m.) mesh perfectly with a 9:15 p.m. return, guaranteeing sleepy kids and satisfied stargazers drift off without generator hum.
Planning a longer stay? Late March through mid-June is peak amphibian season, but eye the first warm rain after snowmelt for the loudest calls. Windy evenings can muffle even a bullfrog’s bellow, so flexible travelers may shift the walk by a week to score calmer conditions. And remember: a new-moon night multiplies constellations once the frogs wrap up, so pack a reclining camp chair and let the universe finish the concert.
When the last ribbit drifts across the cattails, you’re only a 20-minute moonlit cruise from slipping into your own cozy cabin or full-hookup RV site at Junction West Vallecito Resort. Trade the boardwalk for a crackling fire ring, let the marsh music fade into mountain stillness, and wake up ready for trail miles, lake paddles, and—why not—another night of amphibian encore. Spring chorus weekends fill fast, so book your cabin, RV pad, or glamping tent today and let Vallecito’s night symphony kick off an unforgettable mountain getaway.
Frequently Asked Questions
Q: Is the Frog Chorus Tour kid-friendly and grandparent-approved?
A: Absolutely—naturalists keep the pace to a stroller-smooth, ¾-mile boardwalk loop, stop often for listening breaks, and wrap everything in about 90 minutes, so curious grade-schoolers stay engaged without tiring little legs while grandparents appreciate the level footing and chance to pack a collapsible camp stool for quick sits.
Q: How late does the evening run, and will we still be back in time for bedtime or stargazing?
A: Check-in starts at 7:30 p.m., the last frog call fades around 9:00 p.m., and you’ll be rolling out of the parking lot by roughly 9:15 p.m., early enough for kids to crash on the ride home or for couples to linger under a new-moon Milky Way without missing the prime star window.
Q: What should we wear and bring to stay comfortable after dark?
A: Dress in quiet, layered clothing—think fleece instead of swishy nylon—add a rain shell for those frog-loving drizzles, and slip on rubber-soled waterproof shoes for occasionally slick boards; guides hand out red-lens headlamps, but bringing your own keeps the group glow gentle, while insect repellent should be applied back at camp to keep chemicals away from the marsh.
