Denali Field Guide

Denali rises to 20,310 ft / 6,190 m, the highest peak in North America. Across the park, NPS describes three broad elevation zones: lowlands below 2,133 ft, subalpine from 2,132–3,117 ft, and alpine above 3,117 ft. Tree line is roughly 3,000 ft; snow line is generally around 6,000 ft. 123

Black spruce, dwarf birch, and eightpetal mountain-avens are useful names for reading that vertical shift. Denali's vegetation includes nearly 2,000 plant species; the wildlife page counts 39 mammal species, 169 bird species, and one amphibian. 45

For a general visit, the main season runs from May 20 to mid-September: private vehicles reach only the first 15 miles in summer, while transit buses can support day hiking beyond the entrance. Overnight backcountry travel requires a free permit, an orientation, and off-trail navigation. A Denali summit is a separate expedition objective: the typical climbing season runs from late April to mid-July, the West Buttress is the least technical route, and climbers must register at least 60 days ahead. Check current road, bus, weather, and permit conditions before you go. 6789
