Hiking
The Fern and Anona Lake via Summit Meadow Trail offers a rugged, scenic journey into the heart of the Ansel Adams Wilderness. You'll wind through diverse terrain, from Snow Canyon to an open metamorphic rock ridge with sweeping views of Mammoth Mountain, before reaching the serene Fern Lake and the dramatically cliff-bound Anona Lake. This moderate 6.0-mile (9.6 km) hike involves a substantial 2139 feet (652 metres) of elevation gain, typically completed in about 3 hours and 12 minutes, making it a solid day out for those seeking alpine rewards.
Planning your visit requires attention to detail, especially during peak season when access often necessitates using the Reds Meadow Shuttle Service. If you're considering an overnight stay, wilderness permits are mandatory, and bear-resistant food storage is a must. Be prepared for the section beyond Fern Lake, as the trail becomes unmaintained and demands good route-finding skills to reach Anona Lake.
This trail is a fantastic way to experience the raw beauty of the Devils Postpile National Monument and the Ansel Adams Wilderness. From higher points, you can even spot the iconic Minarets, adding to the grandeur of the landscape. Just remember, campfires are prohibited at both Fern and Anona Lakes, as well as at any elevation above 10,000 feet, to preserve this pristine environment.

This route was planned by komoot.
Komoot rates this trail as moderate, but it's important to know that sections, particularly beyond Fern Lake, are considered difficult. These parts are unmaintained and require good route-finding skills. The climb to the ridge above Fern Lake is also moderately steep. Be prepared for a challenging hike, especially if you plan to go all the way to Anona Lake.
The ideal time to hike the Fern and Anona Lake via Summit Meadow Trail is generally from late spring through early fall. During these months, you'll experience the best weather and trail conditions. Earlier in the season, you might encounter partially iced-over sections and numerous small streams from snowmelt, offering unique scenery. Later in the summer, Anona Lake can become shallow and prone to drying up.
Yes, dogs are generally allowed on this trail. However, as it's located within the Ansel Adams Wilderness and near Devils Postpile National Monument, it's crucial to follow all wilderness regulations. This typically means dogs must be kept on a leash, and you are responsible for packing out all waste. Always check the latest regulations before you go.
For day use, a permit is typically not required. However, if you plan an overnight trip into the Ansel Adams Wilderness, a wilderness permit is mandatory. There is a quota of 10 people permitted to start overnight trips on this specific trail each day. You'll also need to adhere to wilderness regulations, including using bear-resistant food storage containers.
Access to the trailhead often involves taking the Reds Meadow Shuttle Service from the Mammoth Mountain Adventure Center. This shuttle operates during certain months, usually from May through early September. When the shuttle is not running, you may be able to drive directly to the Devils Postpile Ranger Station Trailhead. Always check the current shuttle schedule and road access conditions before planning your trip.
The trail primarily consists of ground surface, making it a 'Standard/Terra Trail'. You'll start by following Snow Canyon, then progress towards King's Creek and Summit Meadow. The path gradually climbs a ridge, featuring areas of open metamorphic rock. Beyond Fern Lake, the trail becomes unmaintained in sections. Anona Lake itself is encircled by steep, rocky cliffs, with a stream flowing through a narrow canyon.
This trail offers stunning views throughout. You'll encounter beautiful lakes like Fern Lake (with potential campsites and a beach) and the dramatically framed Anona Lake. The route also passes by the Middle Fork San Joaquin River and provides a View of Devils Postpile. Depending on the season, look out for wildflowers and various wildlife.
Yes, the route incorporates sections of several other trails. You'll spend a significant portion on the Summit Meadow Trail and the King Creek Trail. Closer to Anona Lake, you'll follow parts of the Anona Lake Trail. The route also briefly touches the Summit Meadow - Holcomb Cutoff and the famous John Muir Trail.
Yes, as this trail traverses both the Ansel Adams Wilderness and is accessible via Devils Postpile National Monument, specific regulations apply. Within the wilderness, campfires are prohibited at Fern, Anona, Ashley, Holcomb, or Beck Lakes, or above 10,000 feet. Bear-resistant food storage is mandatory for overnight trips. For Devils Postpile National Monument, there may be entrance fees or specific rules regarding pets and day use, especially during shuttle operation periods. Always check the official park and wilderness websites for the most current information.
Given its 'difficult' sections, particularly beyond Fern Lake where route-finding skills are needed, this trail is generally not recommended for beginners or very young children. While the initial parts might be manageable, the full route to Anona Lake requires a good level of fitness and hiking experience. There are many other excellent, less strenuous trails in the region that might be more suitable for families or those new to hiking.
Fern Lake is noted as having potential good campsites, particularly on its south side beach. However, remember that this trail is within the Ansel Adams Wilderness, and strict regulations apply to camping. No campfires are allowed at Fern, Anona, Ashley, Holcomb, or Beck Lakes, or above 10,000 feet. Overnight permits are required, and bear-resistant food storage is mandatory. Always practice Leave No Trace principles.
