Along the Merced: Yosemite’s River That Keeps the Valley Moving
A river that carved the valley—short hikes, fishing runs and quiet camps along Yosemite’s Merced.
The first time you meet the Merced River it doesn’t ask permission. It announces itself: a low, steady roar under a cedar-and-pine canopy, a silver ribbon flashing through boulders, then a sudden drop into a white-throated run that urges you to step closer. In Yosemite Valley the river is both stage and actor—reflecting cliffs like El Capitan and Half Dome one moment, then racing through riffles that dare you to keep up the next. Walk a few minutes from Yosemite Village and you’ll find it: broad and shallow in places, narrow and urgent in others, a living spine that threads waterfalls, meadows and campsites together.
Trail Wisdom
Start Early for Light and Space
Morning brings cooler temps, softer light for photos, and quieter stretches along the Merced before day-trippers arrive.
Respect Strong Currents
Spring runoff can create powerful flows—avoid swimming in high water and use caution on slick granite near the river’s edge.
Layer for Rapid Temperature Shifts
Bring a light shell and an insulating layer—valley mornings can be cold, afternoons warm, evenings near the river cool.
Pack a Microfilter or Refillable Bottle
While water is everywhere, treat it: use a filter for backcountry fills and carry a refillable bottle to minimize waste.

- •A short scramble to the Merced’s quieter riffles east of the Yosemite Chapel for reflection and fewer crowds
- •The lesser-known cascades upstream of Happy Isles accessible by a moderate day hike

Conservation Note
High visitation and changing snowpack strain river ecosystems—practice Leave No Trace, follow closure notices, and use refillable containers to reduce waste.
The Ahwahnechee people lived and fished along the Merced long before Yosemite became a park; glaciers carved the valley the river now runs through.
Seasonal Guide
spring
Best for: waterfalls, high river flows, wildflower displays
Challenges: cold water and inclement weather, temporary trail or crossing closures
Snowmelt swells the Merced, producing dramatic waterfalls and powerful flows—perfect for views but requiring caution near water.
summer
Best for: swimming holes, day hikes, camping
Challenges: lower flows can limit rafting, crowds in Yosemite Valley
Warm days make for pleasant river swims and comfortable camping; expect busier trails and calmer river stretches.
fall
Best for: quiet hikes, photography, cool-weather camping
Challenges: earlier sunsets, cooler water temperatures
Fall brings quieter trails and crisp air, ideal for photography and longer hikes along the Merced’s quieter reaches.
winter
Best for: snow-laced landscapes, solitude, frosty riverside views
Challenges: icy trails and limited access, cold, fast water after storms
Winter offers dramatic snowy scenery and solitude, but trails and riverbanks can be icy—microspikes and caution required.
Photographer's Notes
What to Bring
Sturdy hiking shoes (approach shoes or trail runners)Essential
Grip and ankle support on wet granite and uneven trails reduce slips around river crossings.
Light rain shell or windbreakerEssential
Protection from sudden showers and river spray keeps you comfortable and warm.
Water purification (filter or tablets)Essential
Reliable filtration lets you refill safely on long hikes or multi-day trips.
Daypack with hydration bladderEssential
Keeps water, snacks and layers accessible for changing conditions along the river.
Common Questions
Do I need a permit to visit the Merced River in Yosemite?
You need a park entrance pass for Yosemite National Park; backcountry or overnight camping requires permits that should be reserved in advance.
Can I swim in the Merced River?
Yes in calmer sections during lower flows, but avoid swimming in high runoff, near waterfalls, or where currents are swift—conditions change quickly.
Is fishing allowed on the Merced River?
Yes—fishing is allowed with a valid California fishing license and adherence to Yosemite’s regulations, which protect native trout; check seasonal rules before you go.
Are there guided rafting or fishing trips on the Merced?
Yes—licensed operators run guided rafting and fishing trips when water conditions permit; booking ahead is recommended in peak seasons.
What's the best time to photograph the Merced River?
Early morning or late afternoon offers the best light and fewer people; spring delivers dramatic flows, while fall gives warm colors and quieter scenes.
How accessible are Merced River trails for families or beginners?
Many valley trails along the Merced are family-friendly and mostly flat, but some riverbanks and side trails include uneven terrain; supervise children near water.
What to Pack
Hydration system (refillable bottle + filter), sturdy shoes for wet granite, layered clothing (shell + insulating layer), sunscreen and hat for alpine sun protection
Did You Know
The Merced River originates in the Sierra Nevada within Yosemite National Park and flows approximately 145 miles before joining the San Joaquin River.
Quick Travel Tips
Reserve campsites and backcountry permits early; check Yosemite’s alerts for trail and river closures; arrive early to secure parking in Yosemite Valley; respect wildlife by storing food in provided lockers.
Local Flavor
Yosemite Valley mixes National Park culture—interpretive rangers, native Ahwahnechee histories, and family-friendly eateries in Yosemite Village—with small nearby towns like Mariposa offering farm-to-table restaurants and local breweries.
Logistics Snapshot
Park entrance fee required; Yosemite Valley has shuttle service to many river trailheads; limited cell service—download maps ahead; overnight permits for backcountry camping required.
Sustainability Note
Stick to durable surfaces, pack out waste, avoid creating new river access points to protect vegetation, and support licensed guides who follow leave-no-trace and fishery regulations.
