Grizzly Giant Loop Trailhead and Parking

The Grizzly Giant Loop Trail in Yosemite National Park starts at the Mariposa Grove Arrival Area. You will see a big sign that says “Mariposa Grove of Giant Sequoias” – that is where you begin your hike!

📍 Google Maps Location: Grizzly Giant Loop Trailhead

🅿️ Trailhead Parking: Mariposa Grove has two main parking lots. The parking area near the grove, known as the Arrival Area, is designated for individuals with a disability placard. Everyone else will have to park at the Welcome Plaza and either hike in via the Washburn Trail (2 miles / 3.2 km one way) or take the shuttle to reach the grove.

🤩 Accessible Grizzly Giant Trail: There is another parking area for those with a disability placard to allow access to a section of the Grizzly Giant Loop Trail. Follow the Mariposa Grove Road all the way to the end until you reach the Grizzly Giant accessible parking lot. There will be a short wheelchair accessible path leading right to the Grizzly Giant and California Tunnel Tree!

🗺️ Distance to Trailhead: Mariposa Grove Welcome Plaza is about 0.2 miles (0.3 km) from Yosemite’s South Entrance and 33 miles (53 km) from the Yosemite Valley Welcome Center.

🚗 Parking Tips: The parking area at the Welcome Plaza is huge with about 300 parking spots! You shouldn’t have too much trouble finding a parking spot there. But if you’re visiting on a summer weekend or holiday, get there early just to make sure you secure a parking spot.

🚻 Facilities: Restrooms (flush toilets), drinking water, bookstore, and visitor information are located at the Welcome Plaza. And at the Arrival Area, you will find restrooms (flush toilets) and drinking water (seasonal).

🚌 Shuttle Option: There is a free shuttle that takes you from the Welcome Plaza to the Arrival Area (Mariposa Grove) and back. It runs seasonally from April through November (dates vary each depending on winter conditions). The shuttle runs every 15 minutes from 8 AM to about sunset time (check this year’s schedule here).

Best Time to Hike the Grizzly Giant Loop Trail in Mariposa Grove

🌷 Spring (March – May): Spring is a great time to visit Mariposa Grove as the melting snow brings lush greenery and vibrant wildflowers to the forest floor. Various wildflowers begin to bloom in late spring/early summer and look so beautiful by mid-summer.

Snow may linger at higher elevation near Wawona Point, especially early in the season. Since the Grizzly Giant Loop Trail is at lower elevation, there’s a smaller chance of snow along that trail in spring – but it’s still possible!

The Mariposa Grove Road usually opens sometime in April. Check current conditions and road closures HERE.

Mariposa Grove is open year-round unless otherwise stated, so even if the road is closed you can still access the grove by foot (or snowshoes/skis). Do your research and make sure you are prepared with winter gear if snow/icy conditions are present!

☀️ Summer (June – August): Summer is the most popular time to explore Mariposa Grove. All the trails are open and accessible, allowing visitors to experience the breathtaking sights of giant sequoia trees. Since this grove is located a higher elevation as compared to the valley, the wildflowers are in full bloom by mid-summer.

The warm weather is especially pleasant in the cooler, shaded forest areas. On the downside, this is also peak tourist season, so expect crowded trails, especially along the Big Trees Loop Trail and Grizzly Giant Loop Trail. If you’re able, you can escape the crowds by hiking towards the upper grove along the Mariposa Grove Trail.

🍂 Fall (September – November): Fall offers a quieter and cooler time to visit Mariposa Grove, with fewer crowds and crisp, pleasant weather.

The autumn colors create a stunning contrast with the towering green sequoias, making it a picturesque time for photography and hiking. Trails remain accessible in early fall but be prepared with winter gear just in case there’s an early season snowstorm!

☃️ Winter (December – February): Visiting Mariposa Grove in winter is an incredible experience! The grove is transformed into a serene winter wonderland. It’s the perfect time to snowshoe or cross country ski through the grove.

In the winter, the Grizzly Giant Loop Trail becomes a bit more challenging due to snow/ice covering the trail. The Mariposa Grove Road is closed during this time so the only way to reach the grove is to hike/snowshoe/cross country ski along the Washburn Trail which will add 4 miles (6.4 km) to the total hike.

Hiking the Grizzly Giant Loop Trail: Step-by-Step Directions

Mariposa Grove Welcome Plaza

This hike, for most people, begins from the parking lot of the Mariposa Grove Welcome Plaza. You have two choices to reach the start of the Grizzly Giant Loop Trail.

The most popular option is to take the shuttle bus. It’s quicker and convenient. However, if get there early, before the shuttle begins running then you will have to hike along the Washburn Trail.

If you have a disability placard, you can park your car at the Mariposa Grove Arrival Area. Only a short section of the Grizzly Giant Loop Trail is wheelchair accessible, so to reach this section, park at the Grizzly Giant accessible parking lot – this will allow you to see the Grizzly Giant and California Tunnel Tree!

Washburn Trail

If you are not taking the shuttle or you do not have a disability placard, then you will have to hike along the Washburn Trail. It’s 2 miles (3.2 km) one way with about 500 feet of elevation gain. It’s a gradual climb through the forest.

It’s a really peaceful and beautiful trail, especially in early to mid-summer when the wildflowers are blooming or in winter when the landscape is covered in snow.

In about 45 minutes to an hour you will reach the Mariposa Grove Arrival Area. Here you will find drinking water (seasonal), flush toilets, and a map of the entire grove.

Grizzly Giant Loop Trail

Let’s begin hiking the Grizzly Giant Loop Trail. You will see a big sign that says “Mariposa Grove of Giant Sequoias” – this where the trail starts.

This section of the trail is the beginning of other hikes as well, including the Big Trees Loop Trail and Mariposa Grove Trail. The Big Trees Loop Trail is a short, easy, and family-friendly trail whereas the Mariposa Grove Trail is challenging but offers a more peaceful experience.

In just 0.1 miles (0.2 km) you will reach the first unique giant sequoia tree known as the Fallen Monarch. This giant sequoia fell many years ago and you can see its incredible root system.

Along this route, you will see many unique giant sequoias. I call them “unique” because they have specific names. Read my “Complete Guide to Giant Sequoia Trees in Yosemite” to learn more about these incredible ancient giants!

At the Fallen Monarch Tree, you will see a trail junction. Continue straight (towards the right) along the Grizzly Giant Loop Trail. You will gain a little bit of elevation here.

At the 0.4-mile (0.6-km) mark, you will come across the Bachelor and Three Graces. It got its name because there are three giant sequoias growing closely together and another one standing a bit in the distance.

Cross the road and continue for about 0.3 miles (0.5 km). You will soon reach the most famous tree in Mariposa Grove – Grizzly Giant.

The Grizzly Giant is the oldest tree in Mariposa Grove, estimated to be around 3,000 years old! It’s also one of the biggest sequoia trees in the grove with a height of about 210 feet and a circumference of more than 90 feet.

It’s not quite as large as the General Sherman Tree in Sequoia National Park or the General Grant Tree in Kings Canyon National Park, but it’s still just as amazing.

Not only is the trunk of the Grizzly Giant massive, but the limbs are huge! Expect to see a pretty big crowd around this beautiful tree. And please stay behind the fence – it’s there to protect the tree.

🤩 If you want to see more incredible giant sequoias, check out the Congress Trail and Big Trees Trail in Sequoia National Park! Speaking of this national park, I have lots of Sequoia travel guides to help you plan a trip.

From the Grizzly Giant, take the trail on the left side of the tree. In 0.1 miles (0.2 km) you will reach the second most popular tree in the grove – California Tunnel Tree.

The California Tunnel Tree was the second tree to be tunneled in Mariposa Grove in 1895. This practice of tunneling trees was done to boost tourism. Thankfully, conservation efforts have evolved, and this practice no longer happens.

Unfortunately, the California Tunnel Tree has weakened, but the bark is growing inward in an attempt to heal itself. This shows how incredibly strong and resilient giant sequoia trees are!

When you visit this tree, don’t just think about how cool it is to stand inside the California Tunnel Tree, but appreciate what this tree has gone through and how it is still living and standing today.

At the California Tunnel Tree, continue following the trail on the left. Do not walk through the tunnel tree – that trail connects to the Mariposa Grove Trail.

In about 0.5 miles (0.8 km) from the tunnel tree, you will come across a junction in the trail. Continue straight to stay on the Grizzly Giant Loop Trail.

Finish the Hike

Follow the trail for another 0.7 miles (1.1 km). You will then join the Big Trees Loop Trail. Take a right to head back to the Arrival Area. This section involves a few gentle switchbacks – thankfully, you are going down them and not up!

In just 0.1 miles (0.2 km) from the junction you will be back at the Mariposa Grove Arrival Area. If the shuttle is running, you can hop on the shuttle to avoid walking another 2 miles (3.2 km) back to your car at the Mariposa Grove Welcome Plaza.

Congrats, you did it! 🥳

Tips for Hiking the Grizzly Giant Loop Trail in Yosemite National Park

1. Protect the Giant Sequoias: Some giant sequoias have fences surrounding them to protect them. Do not cross the fence! It’s there to protect them and help keep them alive for many more generations.

2. Download Offline Maps: The Grizzly Giant Loop Trail is well maintained and easy to follow with trail signs marking the right path. There are a few other trails and side trails that could possibly cause some confusion so download offline maps on your phone (and always carry a physical map and compass).

3. Start Early: Beat the crowds and enjoy cooler temperatures by starting your hike early in the morning, especially during peak season. Just be aware, that you may have to hike along the Washburn Trail (2 miles / 3.2 km one way) to reach Mariposa Grove since the shuttle usually doesn’t start running until 8 AM. But I think it’s worth it to beat the crowds!

4. Check Shuttle Status: The Mariposa Grove shuttle runs seasonally typically from April to November. If it’s not running, then you’ll have to hike an extra 2 miles (3.2 km) one way to reach the grove from the main parking lot.

5. Be Bear Aware: Black bears are active within Yosemite. Follow these guidelines to avoid any negative interactions with a black bear.

🐻 Note: Bear spray is prohibited in Yosemite National Park!

6. Respect Nature: Follow Leave No Trace principles – plan ahead, pack out all trash, avoid disturbing wildlife, be considerate of others, and respect the natural beauty of Yosemite National Park.

What to Bring to Yosemite National Park

🎟️ Entrance Pass – You will need to purchase an entrance pass once you reach the entrance station or you can buy the America the Beautiful Pass ahead of time and use that for the entire year.

👚 Layers of Clothing (top) – Pack a moisture-wicking base layer, a fleece mid-layer, an insulated jacket, and an outer shell to protect you from the elements, such as rain and wind. You may not need all these layers, especially in the summer months, but it’s always best to be over-prepared!

Check out my favorite tops 👇

• Base layer: REI Co-op Sahara Shade Hoodie (warm/mild conditions) and REI Co-op Midweight Long-Sleeve Base Layer (cooler conditions)
• Fleece mid layer: Cotopaxi Teca Fleece Full-Zip Jacket
• Down mid layer: Cotopaxi Fuego Hooded Down Jacket
• Outer shell: In the summer I always pack a light windbreaker, such as the Cotopaxi Teca Crop Windbreaker or the RevolutionRace Unit Light Windbreaker. Make sure to also pack a waterproof rain jacket – I like the Patagonia Torrentshell 3L Jacket.

🩳 Hiking Shorts or Pants – Pack a comfortable, durable, and stretchy pair of hiking shorts or pants. Also think about what conditions you might run into, such as warm or cold temperatures, wind and/or rain, bugs, and overgrown trails.

Check out my favorite hiking bottoms 👇

• RevolutionRace Breezy Ankle Outdoor Pants
• Baleaf Fleece-Lined Jogger Pants

• Revolution Race Hike & Dive Shorts

🥾 Hiking Footwear – Bring a good pair of hiking boots or shoes with good traction. If I’m not expecting to hike in too much mud or snow, my go-to hiking shoes are the Altra Lone Peak trail runners. They have a wide-toe box, 0 mm heel-to-toe drop, and MaxTrac rubber outsole. Plus, they’re lightweight and so comfy!

🧦 Socks – Moisture-wicking, quick-drying socks are the way to go. My favorite pair of hiking socks are Darn Tough Hiker Micro Crew Cushion Socks. Always pack an extra pair!

🎒 Day Pack – What you plan to do (sightseeing, hiking, etc.), determines what size pack you’ll need. Here is what I typically bring based on what I’m doing that day 👇

• Short walks and sightseeing: Cotopaxi Kapai 1.5L Del Dia Hip Pack
• Short, easy to moderate day hikes: REI Co-op Flash 22L Pack
• Long, moderate to challenging day hikes: REI Co-op Trail 25L Pack or Cotopaxi Luzon Del Dia 24L Pack

🥢 Trekking Poles – Essential for stability, balance, and support when hiking trails, especially on tough, rocky, and uneven terrain. I use REI Co-op Trailmade Trekking Poles and love them!

❄️ Microspikes – Bring a pair of microspikes if you’re visiting in the winter and you’re planning to hike along icy trails. They will give you good traction to avoid slipping! I use Black Diamond Access Spike Traction Device.

🦟 Mosquito/Bug Repellants – In the warmer months, be prepared for annoying gnats, mosquitoes, and flies. Wear long-sleeve clothing, a head net, and use bug spray.

🧤 Extra Warm Layers – If you expect cooler conditions or hiking to higher elevations, make sure to pack extra layers for added warmth, such as gloves, beanie, neck gaiter, and a light jacket.

🗺️ Navigation – Carry a physical topographic map, compass, a satellite messenger (or personal locator beacon), and download offline maps to help you stay on course, find your way in unfamiliar terrain, and call for help if needed.

🔦 Headlamp/Flashlight – A reliable light source with extra batteries, in case you end up hiking in the dark or need it for emergency situations.

💧 Water – Water bottles to carry sufficient water to stay hydrated, along with a filtration system or purification tablets if you plan to refill from natural sources.

🍕 Food – Energy-rich snacks or meals to keep your energy levels up during the hike.

😎 Sun Protection – Sunscreen, sunglasses, and a sunhat to protect yourself from harmful UV rays, even when it’s cloudy. Also, polarized sunglasses are important when it’s bright outside and to reduce glare from reflective surfaces like water, snow, and roads.

🩹 First-Aid Kit – A basic first-aid kit with items like bandages, antiseptic, pain relievers, and any personal medications you may need.

🥶 Emergency Shelter – Pack an emergency bivy sack or space blanket for shelter in case of sudden weather changes.

🗡️ Multi-Tool and Repair Kit – A versatile tool/knife and repair kit to handle any task, from preparing food to making repairs.

💩 Waste Disposal Supplies – WAG bags, trowel, toilet paper, pee cloth, wipes, Ziploc bags – be sure to pack out everything!
