Looking for the best dog-friendly hikes in Mammoth Lakes, CA? If you're visiting the Eastern Sierra with your pup, Mammoth delivers big time. From scenic alpine lakes to forested switchbacks, this mountain town is packed with trails dogs love — and they're as photogenic as they are paw-friendly.

In this guide, we're breaking down 5 of the best hikes to do with your dog in Mammoth Lakes, including where to park, trail difficulty, water availability, and sun exposure. 

1. McLeod Lake – The Easiest Dog Hike in Mammoth With Big Payoff

Trail Distance: 1.5 miles round-trip
Difficulty: Easy
Trailhead Parking: Horseshoe Lake parking lot (end of Lake Mary Road)
Water Access: Yes — McLeod Lake
Sun Exposure: Mostly shaded

This quick and easy trail is a must for anyone hiking with dogs in Mammoth for the first time. The McLeod Lake Trail begins near Horseshoe Lake and gently climbs through the pines before delivering you to a stunning, quiet alpine lake. It’s ideal for smaller dogs, older pups, or anyone adjusting to the altitude.

2. Duck Pass Trail to Arrowhead Lake – Best Mid-Distance Hike With Water

Trail Distance: 5 miles round-trip
Difficulty: Moderate
Trailhead Parking: Coldwater Campground trailhead
Water Access: Arrowhead Lake
Sun Exposure: Mixed; exposed near the lake

If your dog loves a challenge, the Duck Pass Trail to Arrowhead Lake is a solid option. You’ll gain around 1,000 feet in elevation over the course of the hike, but the views and cool alpine water make it worth it. This trail has some rocky sections, so bring water, snacks, and maybe even booties if your pup is sensitive to granite.

Arrowhead Lake is one of the best alpine lakes to swim with your dog in Mammoth. Once you reach the lake, there’s room to spread out and plenty of shallow areas for your pup to wade. 

3. Sherwin Lakes – A Classic Dog-Friendly Trail With Great Views

Trail Distance: 4.5 miles round-trip
Difficulty: Moderate
Trailhead Parking: Sherwin Creek Road (gravel, but accessible)
Water Access: Sherwin Lakes
Sun Exposure: Mixed; sun and shade throughout

Sherwin Lakes Trail is a local favorite for a reason. The climb is gradual but steady, offering a decent workout for both human and dog. You’ll travel through aspen groves, cross seasonal creeks, and end at a pair of scenic lakes surrounded by forest.

There are great swimming and lounging spots here, and because the trail isn’t too crowded, it’s perfect for dogs who need a little space. The terrain is a mix of dirt and rocky patches, so pack plenty of water. 

4. Heart Lake via Mammoth Consolidated Mine – Short and Historic

Trail Distance: 1.8 miles round-trip
Difficulty: Easy
Trailhead Parking: Coldwater Campground
Water Access: Heart Lake
Sun Exposure: Mostly shaded

This short but rewarding trail offers a little bit of everything: easy access, mellow climbing, and a gorgeous little lake that doesn’t see nearly as much traffic as its neighbors. Start your hike at the Mammoth Consolidated Mine and head toward Heart Lake on a soft, pine-needle-covered trail that’s gentle on your dog’s paws.

It’s a great pick for late afternoon strolls or senior pups. Keep your dog on leash here — there’s wildlife nearby, and the forest has plenty of distractions. We love this trail for testing out gear and capturing golden hour photos. 

5. Convict Lake Loop – Easy, Flat, and Instagram-Worthy

Trail Distance: 2.5 miles loop
Difficulty: Easy
Trailhead Parking: Convict Lake Day Use Area
Water Access: Constant lake access
Sun Exposure: Fully exposed

The Convict Lake Loop Trail is a great beginner-friendly trail that loops around one of the most iconic alpine lakes in the Sierra. The entire loop is dog-friendly, with wide paths, scenic pullouts, and constant access to the water. It’s a great choice for hot days when your dog might want to dip in and out of the lake.

Because the loop is mostly exposed, we recommend hiking early or late in the day and bringing plenty of water for your dog. 

Final Trail Tips: Hiking in Mammoth With Your Dog

• Leash laws: Most trails require dogs to be leashed. Even if your dog is well-behaved, it's good trail etiquette — especially in high-traffic areas.

• Pack extra water: Not every lake is clean enough to drink from. A collapsible bowl and a good bottle go a long way.

• Leave No Trace: Always pack out dog waste. Poop bags left on the trail don’t count.

• Gear Up: A solid hat, breathable layers, and basic first-aid for you and your dog can turn a sketchy day into a great one.
