Choose Mount Whitney for the highest summit in the Lower 48 — a 35 km, 1,860 m climb to 4,421 m where altitude is the main challenge. Choose Half Dome for a 23 km, 1,460 m hike to 2,694 m that ends with a thrilling 120 m cable scramble. Whitney is the bigger physical test; Half Dome is shorter but more exposed and arguably scarier.
Mount Whitney vs Half Dome — the quick verdict
Both are bucket-list California day hikes that need a lottery permit, but they test different things. The Mount Whitney Trail is a relentless high-altitude endurance climb, while the Half Dome Trail is a shorter hike whose crux is a heart-in-mouth cable ascent up bare granite. Whitney wins on altitude and scale; Half Dome wins on drama and waterfalls. The table below lays out the hard numbers before we break down each factor.
| Factor | Mount Whitney | Half Dome |
|---|---|---|
| Distance (RT) | 35 km | 23 km |
| Elevation gain | 1,860 m | 1,460 m |
| Summit | 4,421 m | 2,694 m |
| Crux | 99 switchbacks, altitude | 120 m cable route |
| Time | 12–18 hrs | 10–14 hrs |
| Permit cap/day | 100 day-use | 300 on cables |
| Best season | Jul–Sep | Jun–Oct |
Which is physically harder?
Mount Whitney is the tougher physical challenge by a clear margin. It is 12 km longer, climbs 400 m more, and finishes 1,700 m higher than Half Dome. That altitude difference is decisive: at 4,421 m the air holds about 60% of sea-level oxygen, so the final ridge reduces strong hikers to a slow rest-step, and roughly a third of permit holders turn back. Half Dome's 2,694 m summit sits low enough that altitude rarely troubles hikers, making fitness and the cables — not thin air — the limiting factors.
Which is more frightening?
Half Dome wins on fear factor. The final 120 m up the dome follows two steel cables set into bare granite at roughly 45 degrees, with 300-metre drop-offs and no rope harness on the standard ascent. In peak season up to 300 hikers queue on the cables, and wet rock turns the climb genuinely dangerous. Mount Whitney has exposure along the ridge near the summit, but nothing demanding the hand-over-hand commitment of Half Dome's cables. If heights unsettle you, Whitney is the more comfortable choice despite its greater length.
How do the permits compare for 2026?
Both use lotteries through Recreation.gov, but the systems differ. Mount Whitney's preseason lottery runs 1 February to 15 March 2026, issuing 100 day-use permits per day. Half Dome runs a preseason lottery in March 2026 plus a daily lottery two days ahead, releasing around 300 cable permits per day. Half Dome's daily lottery gives spontaneous hikers a realistic backup that Whitney lacks. Confirm rules on the official Yosemite National Park and Recreation.gov pages before you apply.
What gear does each climb demand?
Gear choice follows the terrain. Both are best tackled with a light, close-fitting day pack so a 25–35 litre vest carrier like the Salomon ADV Skin 12 works for either. Half Dome rewards a hands-free pack with a low profile for the cables, where the Zpacks Bagger Ultra 25L shines. Whitney's colder, higher summit means carrying more insulation and water, so many hikers size up to a 35-litre pack such as the Patagonia Ascensionist 35L. Gloves are worth packing for Half Dome's cables to protect your hands on the steel.
Which should you choose?
Pick Mount Whitney if you want the prestige of the highest peak in the contiguous United States and you can handle altitude and a very long day. Pick Half Dome if you have less time, prefer a lower-altitude effort, and want the unforgettable thrill of the cables and Yosemite's waterfalls. Many hikers do both in a single Sierra summer — Half Dome in June as a warm-up, Whitney in August at full fitness. Whichever you choose, the Mount Whitney and Half Dome trail pages have the elevation profiles and permit links to start planning.
How do the costs and logistics compare?
Beyond difficulty, practical logistics may decide your choice. Half Dome sits inside Yosemite National Park, which charges a $35 per-vehicle entrance fee and requires you to navigate the valley's notorious summer congestion and shuttle system. Mount Whitney lies on Inyo National Forest land with no entrance gate, but the trailhead at Whitney Portal is a long drive from any major airport — about four hours from Las Vegas or five from Los Angeles. Permit fees are similar: Half Dome costs $10 per person plus the lottery fee, Whitney $6 per person plus a $15 reservation charge.
Accommodation shapes the experience too. Half Dome hikers usually base in Yosemite Valley, where lodging books out months ahead and campsites are gold dust. Whitney hikers stage from the small town of Lone Pine (1,190 m) and the Whitney Portal campground, which also serves the critical role of acclimatisation. For either peak, a well-organised day pack keeps you efficient — a streamlined 20-litre vest such as the Salomon ADV Skin 20 carries a day's water and layers without bulk, while hikers who want a touch more capacity for warm clothing favour a 25-litre haul bag like the Zpacks Bagger Ultra 25L. Whichever you pick, both reward the hiker who arrives rested, acclimatised and on the trail before dawn.
For most international visitors, the deciding factor is time and nerve: choose Half Dome for a shorter, more accessible thrill near a major park, and Mount Whitney when you want the outright prize of the highest summit in the Lower 48.
Frequently Asked Questions
Is Half Dome or Mount Whitney more dangerous?
Half Dome's cable section is more acutely dangerous, with steep bare granite and 300-metre drop-offs that have caused fatalities, especially in wet conditions. Mount Whitney's main hazards are altitude sickness and afternoon thunderstorms. Statistically both are safe for prepared hikers, but Half Dome's cables carry a higher risk of a single catastrophic fall.
Can you hike both Mount Whitney and Half Dome in one trip?
Yes, many hikers combine both in a single Sierra Nevada season. They are about a five-hour drive apart. A common plan is Half Dome in June when the cables go up, followed by Mount Whitney in August once you are fully acclimatised and fit, since Whitney is the harder of the two.
Which has the better views, Whitney or Half Dome?
Both are spectacular but different. Half Dome offers a dramatic perch above Yosemite Valley with views of waterfalls and granite walls, while Mount Whitney delivers a vast high-Sierra panorama from the highest point in the Lower 48. Half Dome is more iconic; Whitney is more expansive and alpine.
Do you need a permit for both hikes?
Yes, both require lottery permits through Recreation.gov. Mount Whitney's preseason lottery runs 1 February to 15 March 2026, while Half Dome has a March preseason lottery plus a daily lottery two days ahead. Hiking either without a permit risks a fine and turnaround by rangers.
Which is better for beginners?
Half Dome is the more beginner-friendly of the two thanks to its shorter 23 km distance and low-altitude 2,694 m summit, provided you are comfortable with the exposed cables. Mount Whitney's 35 km distance and 4,421 m altitude make it a serious step up that beginners should build toward gradually.
