About Mammoth Crest Trail
Mammoth Crest Trail is a 10.5 km hiking route in California, United States. It climbs roughly 298 m (978 ft) along the way, topping out at 3,432 m (11,260 ft). Most people take around 2 hr 38 min at a comfortable pace, plus stops. Expect a steady effort with a few sustained climbs, well within reach if you walk regularly.
The higher sections open out completely, with ridgelines stacking into the distance on clear days.
It runs point to point, so arrange transport at the far end or plan a return leg before you set off. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.
Snow lingers at this altitude well into the season, so the reliable window is short. With a high point around 3,432 m (11,260 ft), late June to mid September is when the route is normally clear.
In short, Mammoth Crest Trail suits regular walkers who want a full day without technical ground. Dog access is not formally recorded here, so check locally before bringing one.

The route in detail
The route is normally walked in the direction described below. The gradient is spread evenly, so there is no single section that dictates your pace. The steepest pitch runs at roughly 70 percent, short but enough to slow most people to a crawl. The upper section is where the route earns its reputation, and it is also where weather changes fastest. Because the finish is away from the start, check return transport before committing to the second half.

Tips from the trail
- Early morning and late afternoon give the best light and the quietest paths.
- Aim for july to september for the most reliable conditions.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- Some sections are steep enough to be awkward in the wet, particularly on the way down.
- At this altitude the weather can turn in under an hour, and temperatures drop fast once cloud arrives.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in United States are reached on 911. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage in the upper sections is patchy at best, so do not count on being able to call for help from the summit. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Sun hat, sunglasses and high-factor sun cream
- Microspikes if you are walking at the edges of the season
- Small first aid kit including blister plasters
Photography
Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Take the shot on the way out. Conditions rarely improve by the time you come back past. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
