Twin Bridges
What to Expect
Safety Advisory
The Lyell Fork looks gentle but runs fast and cold during peak snowmelt in June and early July — keep children well back from the banks and never attempt to wade across.
At 8,600 feet, visitors coming straight from sea level may feel the altitude; take the flat terrain as a gift and stay hydrated.
Trail Details
Pro Tips
Park at the Lembert Dome parking area and walk through the backpackers' parking lot to reach the trailhead — the main lot fills by 10 AM on summer weekends, so arrive early or plan for an evening stroll instead.
The sandy riverbanks at the bridges make a perfect picnic spot, but pack everything out and bring a sit pad — the ground stays damp well into July from snowmelt.
For the best photographs, hit the bridges in the last two hours before sunset when the low-angle light turns the Lyell Fork into liquid copper against the dark granite.
