Full Briefing
You've got ideal Trinity Alps conditions for mid-March. Clear skies through Saturday with daytime highs in the mid-50s and overnight lows in the mid-30s — perfect for comfortable hiking and sleeping. Light northwest winds under 15 mph mean no weather exposure issues on ridges or exposed sections.
Stream crossings are running easy this year. All monitored gauges show flows 41-87% of median and trending stable or falling. The Salinas River near Bradley is at 339 cfs (76% median), which represents the higher end of regional flows, but even this is well within normal crossing conditions. Cold overnight temperatures in the mid-30s will keep snowmelt minimal, so flows won't spike during your trip window.
Snowpack varies dramatically by elevation across the region. Long Lake station at 840 feet shows 98 inches — that's valley snow that won't affect your route. More relevant is Annie Springs at 6,021 feet with 35 inches and falling, indicating settlement rather than active accumulation. No snow concerns for Trinity Alps trails at typical backpacking elevations.
Plan your daily mileage around the 11 hours 46 minutes of daylight. Sunrise at 7:29 AM means you can break camp early and hike in good light. With sunset at 7:15 PM, aim to have camp established by 6:30 PM to set up before dark. Friday night brings a 16% chance of light snow showers, but temperatures staying above freezing mean any precipitation will be brief and won't create trail conditions issues.

About This Route
The Trinity Alps in far northern California are one of the state's best-kept backpacking secrets. This traverse through the Trinity Alps Wilderness passes through granite peaks, alpine lakes, and dense old-growth forests with a fraction of the crowds found in the Sierra Nevada. The route connects several trail systems to create a north-south traverse through the heart of the wilderness, passing pristine lakes including Caribou, Emerald, and Sapphire. The terrain has an alpine character similar to the Swiss Alps at a fraction of the elevation, with green meadows, glacier-carved cirques, and rushing streams. The Trinity Alps see far less traffic than comparable California wilderness areas. Permits are free and self-issued at trailheads. Black bears are present—hang food or use canisters. Water quality is excellent from the many streams and lakes. The area is hot in midsummer; consider September for cooler temps and fall color.
