Hiking into Yosemite’s Ten Lakes Basin places you at the interface between rugged wilderness and serene alpine waters that dare you to test your angling skills at nearly 9,000 feet elevation. The basin’s series of pristine lakes, each reflecting the towering granite walls around them, calls for a thoughtful shift in traditional fishing approaches. Here, the air thins, water cools sharply, and fish patterns behave distinctly compared to lower elevations.

The hike itself is about 6.5 miles one-way from the hiking trailhead near Hetch Hetchy Reservoir, climbing roughly 2,300 feet through forested slopes and rocky clearings. Pines and firs seem to guard the lakes as you ascend, their needles tinkling in the wind with an almost calculating watchfulness. Plan for 4 to 6 hours round trip depending on pace and fishing breaks, and prepare for sections of loose scree and moderate switchbacks that test steady footing.

Once at the lakes, the challenge shifts from terrain to technique. Water temperatures stay cold year-round, which slows fish metabolism and alters feeding behavior. Persistence and gentle presentation become essential. Opt for smaller flies or lures—midges and tiny woolly buggers work better than bulky streamers. Casting patience will repay you; fish are less aggressive and prefer slow, subtle movements. Wind often picks up along the ridges, so bring a rod with quick tip recovery for precise control.

Depth also plays a strategic role. Many Ten Lakes Basin fish congregate near inlet streams or drop-offs where food stirs up, but the cold water means they hug the bottom longer. Use weighted nymph rigs or slow-trolled spoons to reach them without spooking.

Hydration and footwear are key on the approach. The altitude demands steady, regular water intake—aim for at least 3 liters per person for the day—and boots with solid ankle support to handle both uneven trail and lakeshore rocks. The best fishing times tend to be late morning through early afternoon when sun warms shallow edges slightly and fish venture out.

Respect Yosemite’s alpine environment by practicing catch-and-release and minimizing disturbance near shorelines. Observing the water’s behavior—spirits of the wind shaping waves and currents that press against anglers—is as important as perfecting your cast. Here, fishing is an interaction with a fiercely exacting environment rather than a straightforward conquest.

In sum, a trip to Ten Lakes Basin offers not just a test of physical stamina but a rewarding call to adapt and observe, rewarding anglers who approach with both patience and precision.
