The hike up Mount Tallac is one of the iconic hikes in the Lake Tahoe Basin and should be on your list of places in which to travel at Lake Tahoe. The hike is not for the faint of heart, however, as it features approximately 3,500 feet of elevation gain and high exposure.
But the transformative experience takes you along the northern ridge that overlooks Fallen Leaf Lake, through secluded forest and past Floating Island Lake and Cathedral Lake, and then up and across a two-mile stretch of exposed terrain.
The hike to Mount Tallac is a favorite by many Tahoe locals, particularly for full moon hikes and to search for wildflowers. Sunrises and sunsets are also reason enough to hike up to Tallac as the peak features 360 degree unobstructed views.
Some unique wildlife, such as Pika, can be seen toward the top if you listen and look closely in the endless piles of broken granite.
The route to the top of Mount Tallac is highly exposed and generally slow going due to large sections that pass through talus and scree (busted rock of various sizes and states of stability).
Occasionally summer thunderstorms can roll in during the day, or it can just be really windy and cold up top.
Generally speaking, hiking to the top of Mount Tallac takes about 3 hours. The return trip to your vehicle takes approximately 2.5 hours.
Bring more water, food, and layers of clothing than you expect to use.
There are numerous ways in which to access Mount Tallac, but this article will feature the most common route to the top (via Mount Tallac Trailhead).

Considerations for Hiking Mount Tallac via the Mount Tallac Trailhead:
- Parking can get highly congested in the summer, so arrive at the trailhead early to ensure you find a decent parking spot
- Carry more water and food than you would expect on this hike because you’ll be covering 3,500 feet of elevation gain and much of that time is highly exposed
- Be prepared for snowy conditions in late spring and early summer, and the occasional late summer snow or sleet storm
- Adhere to all Leave No Trace principles, particularly the one about packing out your trash
- There are few trail signs and markers on public lands in the Tahoe region, so unless there are tracks to follow, the correct route may be difficult to identify–when in doubt, turn back
- Be prepared for inclement weather and carry plenty of warm clothes
- Leave an itinerary of your plans with someone who’ll call emergency services if you don’t return by your prescribed time
- Dogs are allowed, but keep them on leash and pick up after them
- Check your dog’s paws for wear and bring booties in case they become too raw or turn around before things get serious
Parking Directions for the Mount Tallac Trailhead:
Drive north on SR 89 approximately four miles from the “Y” (intersection of HWY 50 and SR 89) in South Lake Tahoe.
After driving the four miles, take a left (west) onto Mount Tallac Road. Mount Tallac Road sits opposite of the entrance to Baldwin Beach.
Drive along Mount Tallac Road for about 0.4 miles and take a left at the “T” intersection.
Continue along Mount Tallac Road for another 0.6 miles to the trailhead.
Arrive early on busier days such as weekends and holidays in order to claim a parking spot closer to the trailhead, otherwise you may find yourself doing some bonus hiking.
Be sure to fill out a day-use pass (located at the trailhead kiosk) since you’ll be entering Desolation Wilderness for the day.
The trailhead to the Mt Tallac hiking trail is located at the end of Mount Tallac Road.
There’s a green Forest Service gate at the entrance to Mount Tallac Road. The gate is locked between mid-November and May. If you’re planning to hike Mt Tallac during that time, contact the Lake Tahoe Basin Management Unit to determine whether or not the gate is open.
If you do plan to travel to Mount Tallac during the “off-season,” you can still park at the gate and hike the extra mile to the trailhead, just don’t block the gate.
Here’s a map to assist you in finding the parking area for accessing the Mount Tallac Trailhead.
Travel along the Mount Tallac Hiking Trail (via Mt Tallac Trailhead):
Begin your hike up Mount Tallac at the Mt Tallac trailhead at the end of Mt Tallac Road.
Although there are a couple of sections that are somewhat flat, you’re ultimately going to be hiking uphill the entire way. Pace yourself.
The trail initially travels through a forest, and then on the northern ridge overlooking Fallen Leaf Lake.
After hiking along the ridge, you’ll head back into the forest. You’ll hike past Floating Island Lake, which is a great turnaround point for less ambitious hikers and those hiking with younger children.
Continue traveling along the Mt Tallac hiking trail to Cathedral Lake. This lake is a great place to fuel up for the remainder of the hike. You’ll find shade and some cooler temperatures at Cathedral Lake.
Once rested, continue your journey uphill. The distance from Cathedral Lake to the top of Mt Tallac is about 2.5 miles (5 miles round trip). You’ll be fully exposed for the rest of your ascent of Mount Tallac once you leave Cathedral Lake.
The Mount Tallac hiking trail travels up and over a large section of boulders, followed by a field of scree and talus on its way to another ridge.
Once you gain the ridge at roughly 4 miles into your hike, you’ll be treated to views looking into Desolation Wilderness.
Essentially, the trail follows this ridge. But it travels west of Mount Tallac, so in some respects you’ll be hiking up from behind the peak during the final stretch of trail.
Toward the top of Mount Tallac, you’ll have to negotiate some really rocky sections. Definitely be mindful of your steps during this last bit of hiking.
Probably more important is to pay attention when you decide to come back down. It’s easy to check out once you reach the top, but the descents are where most accidents happen.
Lastly, when you do reach the top of Mount Tallac, resist the temptation to permanently park yourself and your crew at the highest point (it’s obvious where it is once you get up there).
Everyone wants to tap the peak, but we don’t want to have to walk all over you and your lunch to do so. Slap the peak, take some photos, and then find someplace else to rest before your descent.
Additional Considerations for Hiking Mount Tallac
Hiking Mount Tallac in the Snow
Snow can last long into the summer on and around Mount Tallac. This makes for unstable footing, blinding brightness, and an additional way for you to get sunburned (as it reflects up into your face).
If you’re venturing up Mount Tallac in late spring or early summer and there’s still a lot of snow, come prepared.
Depending on conditions and time of day in which you’ll be hiking, you may need micro-spikes, crampons, snowshoes, and/or an ice axe to negotiate questionable aspects of the trail.
Also keep in mind that the first snow of the 2017/18 winter in Tahoe was on September 21, the last day of summer.
Speaking of snow, many backcountry skiers and snowboarders venture up Mount Tallac and other aspects of its surrounding ridges for backcountry powder turns. Although, most of those adventurers access Tallac via the Spring Creek Road (a little further north on SR 89). Backcountry skiing and snowboarding Mount Tallac is an entirely different animal compared to hiking the peak during warmer months. And it’s not my forte, so you’ll have to look elsewhere for relevant information.
Hiking with Dogs on Mount Tallac
If you plan to bring your dog, routinely check its paws. There’s not really any question as to whether or not their paws will wear down. It’s more of a question as to how severe they will wear.
The reason their paws are vulnerable is due to all of the granite rocks you’ll be hiking over. The flesh on your dog’s paws will yield far sooner than that granite ever will.
True story … many years ago a former co-worker of mine called me from the top of Mount Tallac. She was requesting help in carrying her dog down.
The dog’s paws were so raw that they began to bleed, and the dog essentially refused to walk because of it.
Needless to say, I wasn’t close by. So, it took my friend and I awhile to reach her. In the meantime, they inched their way down to about a mile from the trailhead. This is where we caught up with them and carried the 80 lbs shepherd out on a makeshift stretcher using hiking poles and a blanket.
Monitor your dog consistently, bring booties for its paws in case things turn ugly, or simply turn around before you reach that point. Floating Island Lake or Cathedral Lake are great spots to elect to finish your hike and turn back.
Leave No Trace on Mount Tallac
Even if it’s the peak of summer, don’t be the tourist wearing flip-flops, board shorts, and a tank top. And make sure you’re carrying more than just the small bottle of water you picked up at the gas station on your way to the trailhead.
Yes, humans have accomplished greater feats with lesser supplies, but why willingly put yourself at risk?
Besides, the more tired and exhausted you get, the lesser you’re inclined to carry that empty water bottle (when you don’t have a backpack to put it in).
Case in point, when I hiked Mount Tallac on August 23, 2017, I collected four of those “disposable” water bottles, a beer can, and a large handful of micro-trash from the trail. This is unacceptable, so please carry a small backpack with extra supplies, and pack out everything you bring (and find along the way).
The trail to Mount Tallac is being “loved to death,” so do your part to ensure it remains beautiful and free of trash.
In addition, I’ve added to the poster some backpacking and hiking wisdom that I’ve gained over the years.
