AR peak identification
Use the iPhone camera view to understand the peaks in front of you when location and sensor context are available.
Yosemite mountain guide
A Yosemite mountain guide for peak identification and private logs
Yosemite is known for walls, domes, and high country peaks that deserve more than a quick photo caption. Epicrest helps iPhone users identify mountain features, browse context, and remember the trip privately.
Field context
Epicrest tools for yosemite mountain guide
Map-based discovery
Browse nearby summits, elevation, prominence, weather, and route context from the map before you commit to a plan.
Pro offline areas
With Epicrest Pro, save a selected Outdoor area before a trip so downloaded map and place context remains available when service is limited.
Private summit journal
Keep summit notes on device, with optional private iCloud sync. Epicrest does not use server-side photo storage for journals.
Separate Yosemite Valley from the high country
Yosemite Valley concentrates famous walls, domes, and waterfalls: Half Dome, El Capitan, Yosemite Falls, and the Mist Trail toward Vernal and Nevada Falls. Glacier Point looks back across that terrain from above when its seasonal road is open. Mariposa Grove is a separate southern destination, while Tuolumne Meadows and the Tioga Road corridor open an entirely different high-country landscape. Hetch Hetchy has its own entrance road and operating constraints. These are not interchangeable stops on a valley walking plan.
Use Epicrest's map to select the exact district, browse nearby peaks and places, and review route detail where data exists. In a safe, open viewpoint, AR labels may help connect a feature to its name, but Yosemite's sheer walls and narrow valley sky create difficult sensor geometry. Compare the label to the map and landforms. Epicrest identifies peak records; it should not be used to infer an ascent line on a cliff, dome, cross-country route, or closed trail.
Make traffic and permits explicit
Yosemite does not require a general entrance reservation in 2026, but the entrance fee still applies and lodging, camping, wilderness, and Half Dome use have separate reservation or permit systems. Half Dome permits are required seven days a week while the cables are up. A map or saved Plan does not confer a permit. If a trip depends on a specific campsite, wilderness itinerary, or cable date, secure that requirement before building the rest of the day.
NPS advises arriving before 9 a.m. or after 5 p.m. during busy periods. Once parked in Yosemite Valley, leave the vehicle in place and walk, cycle, or use the free shuttle. Entrance delays can exceed an hour and valley congestion can last much longer. Tioga, Glacier Point, and Mariposa Grove roads are seasonal; never infer opening dates from a prior year. Trail construction can also impose time-based restrictions, including current work affecting Mist Trail access in 2026. Read the live conditions page before travel.
Prepare for bears, no signal, and fast change
Food storage is a trip requirement, not a campsite detail. Food, drinks, toiletries, trash, and other scented items must be stored correctly. Overnight wilderness users need an approved bear-resistant container; hanging food is illegal. Outside developed areas, remain at least 50 yards from bears. Water, heat, cold, smoke, river flow, rockfall, and elevation create hazards that vary sharply between the valley and high country.
Epicrest Pro can create or refresh an offline Outdoor area up to 50 miles, with up to 15 installed packs in public iPhone version 2.2. Download while connected and carry the official park map plus a separate navigation backup; an offline snapshot cannot update a fire or road closure. During the visit, use AR only from a stationary, safe place. Afterward, record the district, place, route, date, and observed conditions in the private Journal. Entries stay on the iPhone with optional private iCloud sync, and journal photos are not stored on Epicrest servers.
