Frequently Asked Questions

Where does the Lundy Canyon to Twenty Lakes Basin Loop trail start, and is there parking?

The loop typically starts from the Lundy Canyon trailhead, located near Lundy Lake. There is parking available at the trailhead. For those looking to shorten the Twenty Lakes Basin portion, a boat shuttle across Saddlebag Lake can also be utilized, which has its own parking area.

What is the overall difficulty of this hike?

This loop is considered moderate to strenuous. The most challenging part is the steep ascent from Lundy Canyon into the Twenty Lakes Basin, which involves a significant elevation gain over a short distance, often on loose rock and scree. Some sections may require route-finding skills.

What kind of terrain will I encounter on the Lundy Canyon to Twenty Lakes Basin Loop?

The terrain is diverse. You'll start in Lundy Canyon with aspen groves, beaver ponds, and waterfalls. As you climb towards the Twenty Lakes Basin, expect steep sections with loose rock and talus. Once in the basin, the path generally eases, traversing rocky meadows, granite ledges, and wetlands. Early season hikes may also involve snow-packed areas.

What are the main scenic highlights along the route?

The loop is renowned for its spectacular scenery. You'll pass numerous alpine lakes such as Lake Helen, Steelhead Lake, Excelsior Lake, and Shamrock Lake. Dramatic peaks like Mt. Conness provide a stunning backdrop, and Lundy Canyon Trail itself features several beautiful waterfalls and vibrant aspen groves.

What is the best time of year to hike this loop?

The ideal time is typically from late spring through early fall. Late spring and early summer offer wildflowers and cascading waterfalls. Fall is particularly spectacular in Lundy Canyon due to the vibrant aspen colors. Be aware that early season hikes (late spring/early summer) may still encounter snow, especially at higher elevations.

Is the Lundy Canyon to Twenty Lakes Basin Loop dog-friendly?

Yes, dogs are generally allowed on this trail as it is within the Hoover Wilderness. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all hikers. Please remember to pack out all pet waste.

Do I need a permit or pay an entrance fee for this hike?

No specific permit is required for day hiking the Lundy Canyon to Twenty Lakes Basin Loop. There is also no entrance fee for accessing the Hoover Wilderness. However, if you plan an overnight backpacking trip, a wilderness permit is required.

What regulations should I be aware of when hiking in the Hoover Wilderness?

As part of the Hoover Wilderness, it's crucial to practice Leave No Trace principles. This includes packing out all trash, staying on marked trails where possible, respecting wildlife, and properly disposing of human waste. Campfires may have restrictions, especially during dry seasons, so check current conditions.

Does the trail intersect other well-known paths?

Yes, the route also passes through sections of the Lakes Basin Loop Trail.

Are there any options to shorten the hike or make it less strenuous?

Yes, for those looking to reduce the mileage or elevation gain, a boat shuttle service is available across Saddlebag Lake. This can significantly shorten the Twenty Lakes Basin portion of the loop, bypassing a 1.5-mile walk each way and making that section more accessible.

What kind of wildlife might I see on this trail?

The diverse ecosystems along the loop offer opportunities to spot various wildlife. In Lundy Canyon, you might see beavers in their ponds. Throughout the alpine areas, keep an eye out for marmots, pikas, and various bird species. Always observe wildlife from a distance and never feed them.
