About This Route
The Tuolumne River in Yosemite's high country, from Tuolumne Meadows downstream to Pothole Dome and beyond toward Hetch Hetchy, delivers wild trout fishing amid alpine meadows and granite domes. Open year-round with standard regs: no bait, five trout daily limit. Access via Tioga Road (seasonal, late May-October) and trails like the Pacific Crest Trail or Tuolumne Meadows Lodge paths. Target rainbows and browns with dry flies during hatches; water remains frigid year-round.
Safety Considerations
High altitude over 8,000 feet demands acclimatization; ascend gradually to dodge acute mountain sickness, per NPS protocols: rest first day, hydrate aggressively. Fast-moving riffles and cascades risk drowning; mandatory PFDs for all crossings. Mosquito swarms peak July; use DEET 30% and long sleeves. Sudden thunderstorms drop hail and lightning; monitor forecasts via NOAA app. Grizzly-free but black bears roam; use IGBC-certified canisters. Hypothermia from 40-degree waters; probe depths before wading. Flash floods from afternoon storms; camp high. Follow Leave No Trace by dispersing waste 200 feet from water.
Essential Gear
Pack license, 4-weight fly rod, waders, PFD, bear canister (BearVault BV500), altitude meds (Diamox if prone), bug headnet, wading staff, GPS (Gaia app), emergency bivvy, and water filter (Sawyer Squeeze).
