If driving, head towards Marble Mountain Sno-Park, which is the closest significant landmark. From Portland, Oregon, it's about a 1.5-hour drive north via I-5. For those relying on public transport, the nearest major transit hub is in Vancouver, Washington.

The initial section of the trail meanders through dense forest, offering a moderate incline that gradually prepares you for the more strenuous sections ahead. As you ascend, you'll encounter the first significant landmark, Chocolate Falls, approximately 3 kilometers (1.9 miles) from the trailhead. This is a great spot to take a short break and enjoy the cascading waters.### Mid-Trail Highlights Continuing onward, the trail becomes steeper and rockier as you approach the tree line. Around the 6-kilometer (3.7-mile) mark, you'll reach the base of the Worm Flows, a series of lava flows that provide a unique and challenging terrain. Here, the elevation gain becomes more pronounced, and you'll need to navigate through loose volcanic rock and ash. This section can be particularly demanding, so trekking poles and sturdy footwear are highly recommended.### Historical Significance Mount Saint Helens is renowned for its catastrophic eruption on May 18, 1980, which drastically altered the landscape. As you hike, you'll witness the stark contrast between the lush forest and the barren volcanic terrain, a testament to the mountain's powerful history. The Worm Flows themselves are remnants of past eruptions, offering a tangible connection to the mountain's geologic activity.### Final Ascent The final push to the summit is the most challenging part of the hike. At around 8.5 kilometers (5.3 miles) from the trailhead, you'll reach the crater rim. The views from here are nothing short of spectacular, with panoramic vistas of the surrounding Cascade Range, including Mount Adams and Mount Hood. On a clear day, you can even see as far as Mount Rainier.### Wildlife and Flora Throughout your hike, keep an eye out for local wildlife. Deer, elk, and various bird species are commonly spotted in the lower forested sections. As you ascend, the vegetation becomes sparse, but you'll still find hardy alpine plants clinging to the rocky slopes.### Navigation Given the challenging terrain and potential for rapidly changing weather conditions, it's crucial to have reliable navigation tools. The HiiKER app is an excellent resource for detailed maps and real-time trail information, ensuring you stay on course.### Descent The descent follows the same route back to Marble Mountain Sno-Park. While descending, take care on the loose volcanic rock, as it can be slippery. The return journey offers a different perspective on the landscape, allowing you to appreciate the diverse ecosystems and geological features once more.This trail offers a unique blend of natural beauty, historical significance, and physical challenge, making it a must-do for any avid hiker.
