Frequently Asked Questions

How challenging is the Twenty Mile Lakes Trail?

The Twenty Mile Lakes Trail is generally considered difficult due to significant elevation gains. While komoot rates it as 'moderate' based on average hiking speeds, hikers should be prepared for a steep initial ascent, followed by varied terrain including forested sections, a burn area, and a final steep climb to the alpine lakes. The total elevation gain is around 2,225 feet over 12.1 miles round trip.

How long does it typically take to hike this trail?

The estimated duration for hiking the Twenty Mile Lakes Trail is approximately 3 hours and 10 minutes for the 9.6 km route. However, this is a moving time estimate; plan for a full day, especially if you intend to explore the lakes or take breaks, as the trail involves considerable elevation gain.

What kind of terrain can I expect on the trail?

The trail begins with a steep, shaded ascent with switchbacks. It then eases through forested areas with small creek crossings before traversing a unique burned area from a 1994 forest fire. The final section involves a steep climb to the high alpine lakes. Expect heavily bushed sections in shadier parts and potential deadfall in burned areas. At higher elevations, especially during shoulder seasons, snow and ice may be present.

Where is the trailhead for Twenty Mile Lakes Trail and what are the parking options?

The Twenty Mile Lakes Trail is located near McCall, Idaho. The trailhead offers facilities including toilets, but no water is available. Parking is typically available at the trailhead itself. Always check local forest service websites for the most current information on access and parking.

Are there any permits or fees required to hike the trail?

The Twenty Mile Lakes Trail is located within the Payette National Forest. Generally, day-use permits are not required for hiking in national forests, but it's always best to verify current regulations. You can check the official USDA Forest Service website for the Payette National Forest for any specific requirements or alerts: usda.gov.

What is the best time of year to hike the Twenty Mile Lakes Trail?

The trail is typically snow-free and most accessible from July through October. During the shoulder seasons (early July or late October), be prepared for potential snow and ice at higher elevations, which can make navigation more challenging.

What are the main scenic highlights along the route?

The primary highlight is reaching the four distinct mountain lakes: North, South, East, and West Lakes, known for their crystal-clear waters. Along the way, you'll experience varied scenery, from shady forests to unique areas regenerated after a 1994 forest fire, offering views of distant peaks like Lost Art Peak, Sawtooth Peak, Storm Peak, and Storm Dome. Vibrant green grass and wildflowers can be seen flourishing in the burn areas.

Is the Twenty Mile Lakes Trail dog-friendly?

Yes, the Twenty Mile Lakes Trail is generally dog-friendly. However, as it's located within a National Forest, always ensure your dog is under control, preferably on a leash, and practice Leave No Trace principles by packing out all waste. Be mindful of wildlife and other hikers.

Are there facilities or water sources available on the trail?

Toilets are available at the trailhead. However, there is no potable water available on the trail itself. Hikers should carry sufficient water for the entire duration of their trip, especially given the challenging nature of the hike.

Does the trail connect with other hiking paths?

Yes, the route for the Twenty Mile Lakes Trail intersects with other official trails. You will find sections that are part of the Twentymile Lakes Trail (#315) and the Twentymile Trail (#085).

What should I know about navigating the trail's burned areas or higher elevations?

When traversing the burned areas, be aware of potential deadfall across the path. In shadier sections, the trail can be heavily bushed. At higher elevations, particularly early or late in the season, snow and ice may require careful navigation, sometimes by balancing on logs and rocks. Always wear appropriate footwear and be prepared for varied conditions.
