Key Points
- Rafting in Yosemite is a popular day trip or weekend getaway from San Francisco, with the best conditions typically in June and July
- Essential gear includes a personal flotation device, sunscreen, water shoes, and a waterproof bag for belongings

Understanding the Geography and River Systems in Yosemite
Yosemite is home to several rivers suitable for rafting, each offering a unique experience:
- The Merced River flows through Yosemite Valley, providing a scenic float trip with views of iconic landmarks like Half Dome and Yosemite Falls
- The Tuolumne River, north of the park, offers more challenging Class IV rapids for experienced rafters
- The South Fork of the Merced River near Wawona has gentler ripples and swimming holes
The water levels and flow rates of these rivers are heavily influenced by snowmelt from the High Sierra, making spring and early summer the prime time for rafting.
Planning Your Trip from San Francisco to Yosemite
The drive from San Francisco to Yosemite takes around 4 hours, depending on your route and traffic conditions. Highway 120 through Oakdale and Groveland is the most direct route to Yosemite Valley.
To make the most of your trip:
- Leave early in the morning to avoid traffic and maximize your time in the park
- Check road and weather conditions before departing, as winter closures and summer construction can affect travel times
- Make reservations in advance for accommodations, camping, and any guided tours or rentals
Seasonal Considerations for Rafting in Yosemite
The rafting season in Yosemite typically runs from June through July, when water levels are high enough for floating but not too swift for safety. August can still offer good conditions, especially on the Merced River in the Valley.
Spring snowmelt brings faster flows and colder water temperatures, making wetsuits and helmets necessary for some trips. As the season progresses, the rivers become warmer and calmer, more suitable for leisurely floats and family trips.
Essential Rafting Gear and Safety Measures
To ensure a safe and enjoyable rafting experience, always wear a personal flotation device (PFD) and use caution when entering and exiting the raft. Other essential gear includes:
- Sunglasses with a strap
- Eco-friendly sunscreen
- Quick-drying shorts or swimwear
- Water shoes or secure sandals (no flip-flops)
- Waterproof camera or phone case
- Reusable water bottle
Children under 13 must wear a PFD at all times, and rafting may not be suitable for very young children. Follow all posted safety guidelines and listen carefully to your guide’s instructions.

Check with the park’s visitor centers or website for the most up-to-date regulations and advisories before your trip.
Preparing Physically and Mentally for Rafting
While rafting in Yosemite doesn’t require extreme fitness, it’s important to be comfortable in the water and prepared for some physical exertion. Before your trip:
- Practice swimming and basic paddling techniques
- Build upper body strength and endurance with exercises like push-ups and rows
- Mentally prepare for the possibility of falling into the water or encountering unexpected obstacles
With proper preparation and a positive attitude, rafting in Yosemite can be a thrilling and rewarding experience for adventurers of all levels.
