Sequoia National Park, known for its towering trees and breathtaking landscapes, presents unique challenges due to its high elevation. Altitude sickness is a significant concern for visitors, as the park’s elevations range from 1,370 to 14,494 feet. This guide provides crucial information on recognizing, preventing, and managing altitude sickness in Sequoia National Park, ensuring a safe and enjoyable experience for all visitors.
What Are the Altitude Levels in Sequoia National Park?
Sequoia National Park boasts a diverse range of elevations, each presenting its own set of challenges for visitors:
- Foothills: 1,370 – 4,000 feet

| 1 | Arrive and stay in the foothills | 1,370 – 4,000 feet |
| 2 | Explore lower elevation areas, gradually ascending | Up to 6,000 feet |
| 3 | Visit Giant Forest, limiting strenuous activity | 6,500 – 7,200 feet |
| 4 | Begin more challenging hikes, if feeling well | Above 7,000 feet |
| 5+ | Consider higher elevation activities | Up to 14,494 feet (Mount Whitney) |
