Okay, I need to take a breath because I looked at today's score and it's a hundred. A hundred. Not a 97 where there's like one small caveat I'm rounding up. A flat hundred. April in Yosemite, snowmelt at peak, AQI at 36, not a cloud, not a drop of rain in the forecast. This is it. This is the one.
I'm going to try to be calm and useful about this but I'm kind of not calm.
Why April Is the Only Month That Matters Here
Here's the thing people don't fully understand about Mist Trail: the waterfall is the trail. You hike 1.8 miles to stand next to Vernal Fall and get completely soaked by it. That's the experience. And the waterfall is fed by snowmelt from the high country — which means the volume and power of it changes dramatically depending on when you go.
In July and August, it's nice. It's a waterfall. Sure.
In April, after a Sierra Nevada winter, Vernal Fall is thundering. The Merced River comes off the Mist Trail footbridge like something's broken. The mist cloud is so heavy it creates its own micro-weather — you can be in sunlight 30 feet away and step into a drenching fog in seconds. The spray reaches you long before you reach the top of the fall. At midmorning when the sun hits it right, the mist turns into this full arc of rainbow sitting right in front of the Vernal Fall face.
I am not exaggerating. I have photos. I have too many photos.
The Gear Reality
You will get wet. This is not optional. I have seen people show up in regular clothes and cotton hoodies and emerge from the trail looking like they swam across the Merced. Plan accordingly:
- Rain jacket or packable poncho — not optional in April
- Dry bag or waterproof case for your phone and camera. I use a small dry bag stuffed inside my pack. Kipper (my American Eskimo, who cannot come, which is a whole grievance I won't get into right now) would require a full waterproof carrier if dogs were allowed — the spray is real
- Waterproof or water-resistant footwear is helpful on the stone steps near the top — they stay perpetually wet and the trail surface gets mossy
- Change of dry clothes for the car. This isn't pessimism. It's just what you do
Parking (Read This First)
Yosemite Valley parking is genuinely one of the most chaotic situations in the California outdoors and I say that with full awareness that I've driven PCH on a holiday weekend.
Your options:
- Arrive before 7 AM and park at Curry Village or near the Happy Isles Trailhead. You might actually get a spot. This is the only reliable non-shuttle option.
- Take the Valley Shuttle. Park at the Day Use lots near the Valley Visitor Center and catch the free shuttle to Happy Isles (Stop 16). This is genuinely the move for a weekend visit — less stressful, no circling the lot for 40 minutes.
- Book the timed entry permit if required. Check the NPS website before you go — Yosemite has been running timed entry systems during peak season. April is early enough that it's not always required, but confirm ahead of time. Nothing worse than driving four hours only to be turned away at the gate.
The Trail Itself
Happy Isles Trailhead up to Vernal Fall footbridge is 0.8 miles at a gentle grade. Nice warm-up. After the bridge the Mist Trail begins and it is stone steps — roughly 600 of them carved into the granite — heading almost straight up alongside the fall. It's not technical but it is relentless. The 1,000 feet of gain is earned on those steps.
The mist starts at the footbridge and intensifies as you climb. By the time you're on the final push to the top, the steps are wet and the air is thick. This is the part where your rain gear earns its keep and where your phone lives in the dry bag.
At the top: the pool above Vernal Fall is calm, turquoise, and ringed by smooth granite slabs. It's a genuinely surreal scene after the chaos of the ascent. Sit here for a while. You've earned it.
The Light Situation
I know not everyone thinks about this but I need to mention it. Midmorning — roughly 9 to 11 AM — the sun angle hits the mist column from the fall and produces a full rainbow visible from the top of the stone steps. If you are a person who takes photos (hi), this is the window. It doesn't last all day. Early morning you're in shadow. Midday starts getting harsh. The 9 to 11 AM bracket in April is genuinely one of the most photogenic moments in the California outdoor calendar.
Get there early, time your ascent, be at the top around 10 AM. That's the shot.
Is It Worth the Drive from the Bay Area or LA?
Yes. From the Bay it's under three hours to the Valley. From LA it's five and a half. I've driven from SF for worse reasons. A perfect 100-score day on Mist Trail in April happens maybe a handful of times a year. Clear air, peak flow, no rain, moderate temps. If you have a free day this week — go.
