Arnica Lake & Twin Lakes Hike – Banff National Park

It was an August Saturday morning in Banff National Park. Living in the park, unemployed, meant a new adventure every day. I packed up my lunch, started the car, scrolled through my saved hikes on Alltrails and chose a trail at random. The hike to Arnica Lake & Twin Lakes was the winner!

Initially I was looking at the wrong map and thought this was going to be a quick and easy hike… Little did I know the hike to Arnica Lake and Twin lakes is almost 17kms long… To this day I’m thankful I went in unprepared and didn’t know how long the trail was or else I might not have done it – and this is not a trail you want to miss.

Now, let’s go hiking!

Getting To The Arnica Lake And Twin Lakes Trailhead

The trailhead for Arnica Lake and Twin Lakes is located along highway 93, connecting Banff and Radium Hot Springs. You’ll want to park at the parking lot for Vista Lake.

The drive takes about 30 minutes from Banff, just under 2 hours from Calgary, and just over an hour from Radium.

About The Arnica Lake And Twin Lakes Trail

• Distance: 16.6km
• Elevation Gain: 1171m
• Trail Type: out & back
• Trail Rating: moderate
• Estimated Time: 5-6 hours

The Arnica Lake and Twin Lakes trail is up and down, mainly forested, well defined, and has lots of exposed root and rocks; by a lot I mean a LOT. I would recommend wearing quality hiking boots with ankle support as well as using trekking poles (especially if you’re clumsy like me).

The trail past Arnica Lake becomes very wet and muddy which makes it slightly more treacherous. You can hike this trail in any weather, however due to all the exposed roots and rocks on the trail I would recommend hiking to the lakes on a sunny day, or at least when you know the ground will be dry.

The trail is best used from July to September and features golden Larch trees in the fall. The trail is moderately trafficked – I hiked to the lakes solo and passed people throughout the entirety of the trail. Most people only go to Arnica Lake, so on the way to the Twin Lakes you will cross paths with less people. As always be careful and be bear aware – bring your bear spray!

Roundtrip, including a lunch break, this trail took me about 5 hours. However I was hiking at a decently fast pace. I’d plan to be on-trail for about 6 hours.

Fun Fact: This trail is right next to the Continental Divide and the BC/Alberta border.

Hiking To Arnica Lake And Twin Lakes

The trail starts out downhill heading toward Vista Lake, which has the most beautiful green water. Very unique as most of the lakes in the Rocky Mountains are turquoise or blue. At about the 1km mark you’ll have a great view of Vista lake.

After Vista lake it’s a bit of an uphill grind – you’ve got about 3km and 550m of gain until reaching Arnica Lake. Along the way you’ll cross over a few boardwalks & bridges. The trail throughout this section is forested, however closer to Arnica Lake you’ll come to a break in the trees and have an amazing view of the mountains behind you. Not pictured is the famous Castle Mountain (can be seen to the right) for all you mountain enthusiasts out there.

Shortly before Arnica Lake you’ll come the tiniest meadow, which is actually a gorgeous blue pond earlier in the season. Here will be your first up-close view of Storm Mountain, the star mountain of this hike. To get to Lower Twin Lake (the furthest lake) you will actually be hiking around Storm Mountain which means you will get to see it from all angles.

After a bit more uphill trekking, you’ll reach Arnica Lake with its mysterious green scree rock (seriously if anyone knows why these rocks are green please comment below). This was arguably my favourite lake of the 4. There was no wind which made for a perfect reflection. I had the lake to myself (minus the little chipmunk who was fascinated by my trekking poles) and was able to sit on the shore, eat some oatmeal out of my favourite Stasher Bag & watch the fish come to the surface of the water. Such a peaceful moment.

From Arnica Lake to the Lower Twin Lake it’s about 3km. There’s a little surprise at the end, so make sure you complete the entire hike!

After a little more uphill trekking its all downhill until you reach The Twin Lakes. First is Upper Twin Lake with its beautiful blue water. I was lucky that the wind held off here – another perfect reflection. At this point in the hike, even in late summer, it’s not uncommon to see patches of snow up on the mountain.

Twin Lakes Campground (Tw7) is located just after the Upper Twin Lake if you want to make this hike into a backpacking trip.

More downhill trekking brings you to the last lake of the hike, Lower Twin Lake. The wind picked up and it started raining as soon as I got here which meant no reflection. But, to my surprise, there was a waterfall streaming down from the snow patch!

Beware – the path along the edge of the lake is super muddy.

Just before Lower Twin Lake there are Parks Canada signs, one indicating a route for a viewpoint. Apparently if you take this path you will come to a place where you can see all 3 lakes.

What To Wear Hiking in the Rockies

For a detailed guide on what to wear hiking in the Canadian Rockies, check out this post.

Choosing what to wear hiking can be confusing, but the secret to properly dressing for a hike is layering. You can mix and match the tops and bottoms you already own to make up your base layers, however in addition to those clothes you’ll need a few extra things:

Rocky Mountain hiking exposes you to different natural elements and conditions – it’s imperative that you’re prepared for whatever nature throws at you. Trust me, I’ve learned the hard way!

Arnica And Twin Lakes Trail Extensions

This hike connects to plenty of other backpacking trails and campsites in the area. If you want to make it a multi-night trip you can camp at Twin Lakes Campground (Tw7) and then continue on to Shadow Lake Campground (Re14). Alternatively, if you want to treat yourself, you can stay at Shadow Lake Lodge accessed only via hiking.

From Shadow Lake you can also continue on to Ball Pass Junction (Re21) and if you’re really eager you can head to Egypt Lake Campground (E13) which also happens to have a backcountry shelter. Although if you’re going to do this I’d recommend hiking it in reverse, start with Egypt Lake and end with Twin Lakes.

Carrying all your backpacking gear on this trail would make it a tough multi-night hike, but it would definitely be worth while as it is such a beautiful area
