Union Point

Overview

Union Point is a signed mid-trail overlook on the Four Mile Trail with huge views across the Valley—Yosemite Falls straight across, El Capitan to the west, and Half Dome anchoring the east. It’s foot-access only and makes a fantastic turnaround spot whether you’re hiking up from the Valley or down from Glacier Point.

Getting There

• From Yosemite Valley (Southside Drive near Swinging Bridge): roughly 6–6.4 miles round trip to Union Point with about 2,400 feet of gain. Expect steady, switchbacking climbing and constant views. Plan on about 4–5 hours for most hikers.
• From Glacier Point: about 3.7–3.8 miles round trip. You descend first, then regain ~950–1,150 feet on the return. Figure 2–3 hours. This is the easier way to sample the best scenery without committing to the full Four Mile grind.

What You’ll See

Wide-open vistas the whole way: Yosemite Falls thundering across the canyon, El Capitan’s monolith, Cathedral Rocks and Sentinel Rock, and the Half Dome–High Sierra skyline. The overlook sits just a few steps off the main trail—don’t skip it.

Seasonality and Closures

Four Mile Trail typically opens in spring and often closes in winter due to snow/ice; after big storms, larger sections can close. Glacier Point Road is also seasonal—when it’s closed, Union Point is only reachable from the Valley. Always check current conditions before you go.

Facilities and Logistics

There are no amenities at Union Point. Use restrooms near Swinging Bridge Picnic Area (by the Valley trailhead) or at Glacier Point. There’s no drinking water on the trail; carry your own. There’s no free shuttle between Glacier Point and the Valley—if you’re planning a one-way hike, arrange transportation in advance or be ready to hike back.

Difficulty and Safety

This is a sustained, steep hike with many switchbacks. Some sections are sandy or over old pavement and can be slippery, especially on the descent. Start early to beat heat and sun exposure, bring ample water (think 2 liters for one-way, 4 liters if doing a full round trip), and use sun protection. Keep food secure and stay on the trail—don’t cut switchbacks.

Best Time to Visit

Start early for cooler temps, easier parking, and softer light. Midday brings more sun and more people from both directions. Morning light favors Yosemite Falls and the north wall; later afternoon light flatters Half Dome and the high country. Weekdays see lighter traffic than weekends in peak season.

Photography Notes

The approach itself is a rolling highlight reel, but Union Point offers a clean, unobstructed panorama. Morning for the Falls; afternoon for Half Dome. If you’re descending from Glacier Point, budget time to shoot on the way back—your climb is the crux.

Wildlife

Keep your eyes open—occasional sightings along this corridor have included bobcat. Observe from a distance and never feed wildlife.
