This challenging hike typically requires around 6.5 hours to complete. It's best to start early to allow ample time to enjoy the scenery and account for breaks.
Given its 'difficult' rating, a distance of nearly 18 km, and an elevation gain of over 500 meters, this trail is not recommended for beginners or young children. It requires a good level of fitness and hiking experience.
While specific terrain details for this particular trail are not provided, trails rated as 'difficult' in mountainous wilderness areas like Weminuche often feature varied terrain including rocky paths, steep ascents and descents, and potentially uneven surfaces. Hikers should be prepared for a strenuous experience.
The trail leads to the stunning Crater Lake (Weminuche Wilderness) itself, offering breathtaking views. You will also pass by Andrews Lake, which serves as a beautiful starting point or a scenic stop along the way.
Based on the equal elevation gain and loss, this trail is typically an out-and-back route, leading you to Crater Lake and returning along the same path. This allows you to experience the views from both directions.
The trail is associated with Andrews Lake, which is a common access point for trails in the Weminuche Wilderness. Parking is generally available at designated trailheads near Andrews Lake, but it's always wise to arrive early, especially during peak season, as spaces can fill up quickly.
The Crater Lake Trail is located within the Weminuche Wilderness, which is part of the National Wilderness Preservation System. While there are generally no entrance fees for wilderness areas, specific permits may be required for overnight stays or certain activities. It's advisable to check the official US Forest Service website for the San Juan National Forest (which manages parts of Weminuche) for the most current regulations regarding permits and any fire restrictions before your visit.
Dogs are generally allowed in the Weminuche Wilderness, but they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Please remember to pack out all pet waste.
The best time to hike the Crater Lake Trail is typically during the summer and early fall months (July through September) when the snow has melted and the weather is generally favorable. High-elevation trails in wilderness areas can be covered in snow and ice from late fall through early summer, making them inaccessible or requiring specialized equipment.
For a difficult, full-day hike like this, you should bring plenty of water, high-energy snacks, appropriate layers of clothing for changing mountain weather, sturdy hiking boots, sun protection (hat, sunscreen), a map and compass or GPS device, and a first-aid kit. Bear spray is also recommended for wilderness areas.
Yes, the route primarily follows the 'Crater Lake Trail'. However, it also briefly intersects with sections of the 'Andrews Lake Fishing Trail', the 'Andrews Lake Horse Trail', and the 'Andrews Lake Trail' near the starting point around Andrews Lake. These intersections are minor and the main path to Crater Lake is well-defined.
