The best walks and hikes in Kahikinui Forest Reserve

If you're looking for Haleakala Crater hiking trails that transport you to another world, the Sliding Sands Trail is a must-do. This 4.3-mile (6.9 km) out-and-back route plunges you into the heart of a volcanic crater, offering sweeping lunar-like vistas of colorful cinder cones and unique volcanic rock formations. You'll navigate loose volcanic sand and ash, feeling like you're walking on Mars, with the chance to spot the rare Haleakalā Silversword plant.

Planning your visit requires preparation for the unique challenge of this trail. It's rated moderate, but don't let the downhill start fool you; the 1254 feet (382 metres) of elevation gain on the return climb is strenuous, especially at nearly 10,000 feet of altitude. The estimated time is 2 hours and 21 minutes, but allow extra time for the uphill slog. There's no shade or water on the trail, so carry plenty, and be ready for rapid weather changes and strong winds.

What makes the Sliding Sands Trail truly notable is its unparalleled access to the Haleakalā crater floor and its otherworldly landscape. It's considered the premier access point for exploring the interior of the crater, offering a unique geological experience found nowhere else. Many hikers combine this with a sunrise viewing, making it a truly unforgettable adventure in Haleakala National Park.

The Sliding Sands and Halemau'u Trail Loop offers an unparalleled journey through Haleakalā National Park's volcanic heart, starting with a descent into the crater that feels like stepping onto another planet. You'll navigate a landscape of vibrant cinder cones and ancient lava flows, spotting the unique silversword plants before climbing out past features like the Bottomless Pit (Kawilinau). This difficult 14.2-mile (22.8 km) hike, with 2986 feet (910 metres) of elevation gain, typically takes around 7 hours and 13 minutes, making it a full-day commitment for experienced hikers.

Planning for this point-to-point route requires arranging a shuttle or ride between the two trailheads. Starting at nearly 10,000 feet, you'll need to be prepared for high altitude, intense sun, and potentially cold, windy conditions, so pack plenty of water, sun protection, and layers. The most common approach is to descend via Sliding Sands and ascend via Halemau'u, which is generally considered less strenuous overall.

What truly sets this loop apart is its immersive, otherworldly scenery, often compared to Mars, combined with the unique opportunity to see the endangered Haleakalā silversword in its natural habitat. It's a challenging but incredibly rewarding experience that showcases the raw geological power of Maui's dormant volcano, offering panoramic views that change dramatically as you traverse the crater floor and climb back to the rim.

If you're seeking a quintessential Mount Rainier experience, the Skyline Trail delivers with its stunning alpine scenery and diverse terrain. This moderate 9.2-mile (14.8 km) hiking loop takes you through vibrant subalpine meadows, past cascading waterfalls, and offers close-up views of Mount Rainier's glaciers. You'll encounter everything from paved sections to rocky paths and stone steps, with the reward of panoramic vistas from Panorama Point.

Plan your visit between late July and September, with late July to mid-August being ideal for catching the wildflower bloom. The trail involves a significant 1731 feet (528 metres) of elevation gain and takes approximately 4 hours and 30 minutes, so bring plenty of water and sun protection as shade is minimal. Snow patches can linger at higher elevations even into August, so be prepared for varied conditions.

The Skyline Trail is renowned for showcasing nearly all of Mount Rainier National Park's natural wonders in a single hike, making it an iconic choice for visitors. Beyond the main loop, you have options to extend your adventure towards Camp Muir for an even more alpine experience, or take alternative routes like the Golden Gate Trail for a steeper but quicker ascent.
