Exploring Yosemite's Premier Fly Fishing Spots

Yosemite National Park is a destination for world-class fishing, as its rivers, creeks, and lakes offer varied opportunities for fly fishing. Whether you’re advanced or just starting on your angling journey, the park can accommodate all levels of expertise.

When thinking about Yosemite’s remarkable locations, a few spots come to mind: the Merced River, Tuolumne River, and Lyell Fork, each abounds with fish. And the amazing, natural views can't be beaten!

Tuolumne River: Rainbows, Brookies & Brown Trout

The Tuolumne River has its beginning in Tuolumne Meadow. At approximately 8600 ft., it is the largest sub-alpine meadow in the Sierra Nevada. The Tuolumne River flows through the tall grasses of Tuolumne Meadows. Rainbows, Brookies, and Brown Trout inhabit this section of the river. The Brown Trout here grow to approximately 14 inches. Dry fly fishing is the best and most exciting technique in the meadow section. If the fish don't spook they'll readily accept most standard dry flies. (size 16" - 22") Matching the hatch is not necessary here, but the fish will become selective when there is a good hatch in progress. In the evenings, starting in June and running through early October, the fish will key on the pale morning dun hatch. Small yellow stoneflies (yellow sallies) also show themselves at this time of year. Several different species of caddisflies also inhabit this section of the river and can generate a lot of activity in the evenings. Keep in mind that only artificial lures or flies with barbless hooks are allowed in Yosemite National Park. (No bait fishing, i.e. worms, live or dead minnows, bait fish, etc.)

Yosemite Tuolumne River Trout

Dana Fork: Rainbow, Brook & Brown Trout

The Dana and Lyell Forks converge to form the main Tuolumne River. Dana Fork waters originate from 13,100' Mount Dana. The Dana Fork is very accessible as Highway 120 runs right alongside its entire course from its headwaters at Tioga Pass to its confluence with the Lyell Fork. Rainbow, Brook, and Brown Trout are present throughout, with the Browns being the most numerous, sometimes reaching a foot in length.

Lyell Fork: Numerous Wild Trout - Rainbow's & More

The Lyell Fork originates near 13,115' Mount Lyell and flows 10 miles downstream through Lyell Canyon, where it meets the Dana Fork to form the Tuolumne River. There is no road access here, except at the lower end, but the river is accessible via the PCT (John Muir Trail), which runs its entire length. Although the trail is highly traveled, very few are there to fly fish. The Lyell Fork has a healthy population of Wild Trout, with more Browns in the lower section and more Brook Trout found towards the headwaters. The Rainbow Trout are usually in the faster-moving sections. The Lyell Fork offers fantastic dry fly action. With a good presentation, the fish will rise to most of your attractor patterns (14" - 20"), like Humpies, Elk Hair Caddis, Adams, and Royal Wulffs. Again, stealth is more vital than matching the hatch here.

Merced River - Inside Park: 3 to 1 Rainbows to Browns

The Merced River is the most well-known river in Yosemite, as this is the river that flows through Yosemite Valley. Yosemite Valley is one of the most picturesque places on earth and has much to offer any fly fisherman. The vast majority of my experience has been downstream from Yosemite Valley, where the river changes from long, slow-moving pools to pocket water and deep runs for a mile or so before heading down the Merced Gorge. The gorge is roughly 8 miles long, and although Hwy 140 runs parallel to the river, there are very few turnouts. Where there is access the canyon walls are very steep and rocky. Upon reaching the water the going is anything but easy. Huge boulders and log jams litter the river bottom. I like to wet-wade this section starting in late June or early July after the runoff waters recede. I have fished this area numerous times and have very rarely ever seen another fly fisherman. The catch here will usually run 3 to 1 Rainbows to Browns. Hatches will include small BWOs during warm days in late January and February. The first Golden Stoneflies will appear in February, also. With the days of February growing longer the water will start to warm and we will start getting our first decent action of the year.

Yosemite Merced River Inside Park

South Fork - Merced River: Rainbows, Browns & Brookies

The South Fork of the Merced is the first water encountered upon entering the park from the southern entrance. The South Forks originates in the Chain Lakes area and then flows 30 miles east to west to its confluence with the main Fork. The most accessible area is in Wawona, with Highway 41 following the river downstream for a couple of miles and access roads on both sides of the river heading upstream for a few miles. The road on the south side of the river will lead you to the "Swinging Bridge" area. There's a trail here heading up a mile or so before disappearing into the South Fork Canyon. There is a large trout population in the South Fork. However, they only average around 6 inches. In the Wawona area, the trout are all Rainbows and Browns, which give way to Brook Trout in the higher reaches. The South Fork is not a very fertile stream but there are some early-season Stoneflies (size 14 - 16) (fly shown above), and different Mayfly hatches after the spring runoff recedes. The fish are not very selective but will more easily spook when the water gets very low in the fall. This is a great fishing location for the beginning fly fisherman in the late spring and early summer.

Timing Your Yosemite Fly Fishing Adventure

For the ultimate Yosemite fly fishing excursion, it's important to choose not only suitable equipment and lures but also the best time of year to visit.

Fishing Season and Regulations

Stream and river fishing in Yosemite is open from the last Saturday of April until November 15th, giving anglers plenty of time to cast their lines. Frog Creek opens June 15th. All other lakes and reservoirs are open year-round. All fishermen should check with the National Park Service and California Department of Fish and Wildlife for current regulations on fish size limits, use of flies or lures, as well as fly fishing techniques, like using barbless hooks instead of lead weights. Or enlist the help of a knowledgeable and experienced guide.

Best Months for Fly Fishing in Yosemite

Many consider the fishing season in Yosemite National Park to be at its best during late June to July when the snow runoff makes for optimal conditions, diverse trout populations, and peak activity. Visitors can enjoy access to many top fishing spots while experiencing all that the valley has to offer surrounded by natural beauty in full bloom. But parts of Yosemite can be fished year-round. Lure or fly casting using only artificial lures adds an exciting challenge even year-round anglers can appreciate as they explore great fishing opportunities within one of America’s most beloved parks!
