Frequently Asked Questions

Where is the trailhead for the Twenty Lakes Basin and Saddlebag Lake Loop, and is parking available?

The trailhead for this loop is located at the end of the road leading to Saddlebag Lake, within the Inyo National Forest. Parking is available near the lake, often at the Saddlebag Lake Campground or the Saddlebag Lake Resort area. It's advisable to arrive early, especially on weekends, as parking can fill up.

Are permits required to hike the Twenty Lakes Basin and Saddlebag Lake Loop, and are there any entrance fees for Inyo National Forest?

Day hiking the Twenty Lakes Basin and Saddlebag Lake Loop does not require a permit. However, if you plan to backpack and stay overnight in the Hoover Wilderness, a wilderness permit is required. There are no entrance fees for Inyo National Forest itself, but some developed recreation sites or campgrounds may have fees.

Is the Twenty Lakes Basin and Saddlebag Lake Loop dog-friendly?

Yes, dogs are generally allowed on this trail. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all hikers. Always remember to pack out any waste.

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

The best time to hike this loop is typically from late June or early July through September or early October. During this period, most of the snow has melted, and the weather is generally more stable. However, even in late summer, be prepared for rapidly fluctuating temperatures and potential lingering snow patches at higher elevations.

What is the terrain like on the trail?

The terrain is characteristic of an alpine environment, featuring imposing granite landscapes, rolling hills, and rocky sections. You'll navigate polished granite slabs, remnants of glacial activity. The path along the west side of Saddlebag Lake can be particularly rocky. While generally not overly strenuous, there are steady inclines and declines, especially when ascending into the Twenty Lakes Basin or crossing Lundy Pass.

What kind of scenery and natural features can I expect to see along the route?

The scenery is breathtaking, with numerous charming and vividly colored alpine lakes such as Steelhead Lake, Shamrock Lake, Lake Helen, Excelsior Lake, and Greenstone Lake. Dramatic peaks like Mount Conness and North Peak provide a spectacular backdrop. You'll also encounter beautiful alpine meadows, cascading streams, and potentially waterfalls.

How challenging is the Twenty Lakes Basin and Saddlebag Lake Loop?

This loop is generally rated as moderate. While some portions have minimal elevation changes, the climb into the Twenty Lakes Basin can be steep for about a mile. The high altitude (reaching around 10,364 feet) means hikers should be prepared for thinner air and potential weather changes. It's suitable for a wide range of hikers with a reasonable level of fitness.

Is there a way to shorten the hike, or a recommended direction to hike the loop?

Yes, a unique feature of this trail is the option to shorten it significantly by utilizing a water taxi across Saddlebag Lake, which saves about 1.5 miles each way. Many hikers find that completing the loop in a counter-clockwise direction offers better views of the mountain scenery as you progress.

What wildlife and wildflowers might I encounter?

The trail offers opportunities for wildlife viewing, though specific sightings can vary. You might spot marmots, pikas, various bird species, and possibly deer. In late spring and early summer, the alpine meadows are dotted with a vibrant array of wildflowers.

Does this route connect with other trails?

Yes, this route incorporates sections of other established paths. Approximately 52% of the route follows the Saddlebag Lake Loop Trail, and about 24% traverses the Lakes Basin Loop Trail, offering a comprehensive experience of the area.

What should I bring for a day hike on this loop?

Given the high-altitude alpine environment, it's crucial to bring plenty of water, extra layers of clothing (even in summer, temperatures can drop quickly), sun protection (hat, sunglasses, sunscreen), sturdy hiking boots, and snacks. A map and compass or GPS device are also recommended, along with a first-aid kit.
