Bertha Lake Trail – Waterton Lakes National Park

During the summer of 2021 I made two trips to Waterton Lakes National Park. Two trips because the first was so good I had to come back and explore more! On my second visit I hiked the beautiful Bertha Lake trail.

The hiking in Waterton is fantastic, and Bertha Lake is no exception. A friend of mine, who previously lived in Waterton for a summer, recommended this trail to me. It happens to be a local’s favourite and one of my favourites too.

This trail features two waterfalls, multiple lookouts points, a glacial lake complete with Waterton’s famous red rock, and plenty of chances to see wildlife. A must-do hike in Waterton!

Now, let’s go hiking!

Getting To The Bertha Lake Trailhead

The Bertha Lake trailhead is very accessible – it’s located 15 minutes (walking) from town and is situated across the road from the Townsite campground. Perfect if you’re camping there!

If you’re looking for hiking trails near Lethbridge, this is only 1.5hours away. The trailhead is about 2 hours from Fernie, 3 hours from Calgary, and 4 hours from Banff. You could easily drive from any of these locations to make this a day-trip, but I would recommend staying at least 1 night in Waterton because there is lots to do!

If you’re driving from Calgary or Banff, make sure you take highway 22. This highway takes you through the foothills and is absolutely gorgeous. You’ll have the chance to pass through the greenest rolling fields which are backed by distant mountains that appear blue in colour. You’ll be passing by lots of farmland, so prepare to see lots of horses and cows too!

About The Bertha Lake Trail

  • Distance: 12.4km (+4km to walk around the lake)
  • Elevation Gain: 620m
  • Rated: moderate
  • Type Of Trail: out & back
  • Estimated Time: 4-5 hours

The Bertha Lake trail is comprised of 3 main sections; Lower Bertha Falls, Upper Bertha Falls, and Bertha Lake – you will come across them in that order.

Bertha Lake is one of the most popular hiking trails in Waterton which means it is well trafficked. If you want to beat the crowds, leave early or start late. Due to the fact Bertha Lake is such a popular hike, you can safely solo-hike this trail. As always, be bear aware and bring your bear spray.

The trail itself is very easy to follow and is well maintained. For the most part the trail is clear so you won’t have to worry much about maneuvering around rocks and roots. Once you start gaining elevation, you’ll be following 21 switchbacks up the mountain. There are shortcuts within the switchback section – if you use these make sure to stay on the cleared areas as not to interfere too much with the surrounding vegetation.

The trail is best used from April to October, but you could easily hike this in the winter as well if you have the proper gear (micro-spikes/snowshoes).

If you’re looking for more of a challenge, consider hiking to Bertha Peak.

Hiking The Bertha Lake Trail

Bertha Lake Trailhead to Bertha Point

I will first start off by recommending to do this hike on a sunny, warm day. Getting to the top and taking your time exploring the lake under the sun… Nothin’ quite like it.

I was greeted right away by a family of deer on the trail!

The deer and myself did not want to re-route our path, so I ended up having to step aside into the bush to allow them passage.

I’ve never had deer be so unbothered by humans before!

Highlight was the little baby behind them which still had its white spots.

You have a great chance of seeing wildlife on this trail, especially if you start early in the morning.

The first notable point of interest on this trail is Bertha Point which overlooks Upper Waterton Lake. This is an excellent spot for sunset and a great photo opportunity. 1.5kms with less than 100m gain will get you to this point. You’ll be able to complete this section in about 20 minutes.

After the lookout point you’ll be en route for Lower Bertha Falls.

1.3km and 80m of gain will get you here. Along this section of the hike you are walking alongside the creek, so enjoy the sounds of flowing water.

As of summer 2021 the lower falls were closed due to bridge construction – you can check the current status of the construction here.

Hikers now use the horse detour to get around the falls. You will see signs directing you.

I have been told that earlier in the season these falls are gushing much more compared to when I completed this trail in early September.

After the lower falls you will cross the creek and start climbing up the 21 switchbacks leading to the lake.

From here it’s all uphill until you hit the lake – approximately 3km, 300m gain, and 1.5-2 hours from the trailhead

Along the way you will come across a few lookout points as well as Upper Bertha Falls. There is no good lookout point for Upper Bertha Falls, only a small clearing in the trees.

The falls are extremely tall and very beautiful, but difficult to view!

Bertha Lake

Bertha Lake has amazing blue water and is very crypt-like, meaning it’s hidden in an alpine bowl surrounded by cliff walls. The views from here are pretty great, but I would definitely recommend hiking an extra 4km to loop the lake.

Upon arriving to the lake, I headed left to start the loop – if you’re going to the Bertha Lake campground hang a right. Doing the loop allows you to see the lake from different angles and you get a chance to see the waterfalls and alpine streams coming down the mountains that you’re unable to see from the shore you initially see the lake from.

Another plus is you get to avoid the crowds and can find secluded, peaceful spots all to yourself.

The blue colour of the lake seemed to change as I made my way around too, starting out light, then turning to a deep, rich blue.

My absolute favourite thing about this lake, which was also a complete surprise, was the red rock along the shore! I loooove Waterton’s red rock and was not expecting to see any here. However once you loop the lake and come around the back-side, the entire North shore of the lake is lined with these red beauties.

If you’re looking for some insider scoop, I laid on the beach like a crazy person for 20 minutes working with different angles to get this shot on my trusty old iPhone XR.

After you’re done exploring the lake you’ll get to hike down, taking in the views of the Waterton Valley.

Recommended Hiking Gear

The following items are some of my favourites – I never hit the trail without them!

PD Capture Clip

The Capture Clip by Peak Design is a sturdy, safe, and super convenient way to carry your camera while hiking or backpacking.

Find it on Amazon (CAD).

Find it on Peak Design (US).

Hydration Reservoir

A hydration reservoir is SO important. It holds 2L+ of water and keeps you hydrated on-trail. I use the 2L Hydrapak; it never leaks and has a detachable tube.


Things to look for in a good quality day-pack: sternum strap, hip belt (with pockets), and a breathable mesh system for your back. I use the Osprey Sirrus 24L pack (men’s version) and I LOVE it!

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:

Waterproof Jacket

A waterproof jacket is the most important layer for hiking – it keeps you warm and protects you from wind and rain. I use the Marmot Eco Precip Jacket (men’s version) which is totally a bang-for-your-buck. If rain is in the forecast, don’t forget to pack waterproof pants (men’s version) too.

Hiking Boots

A good pair of hiking boots are Gore-tex, provide ankle support, and are durable. I use the Scarpa Kailash boot (men’s version) and they’ve never let me down. You’ll also want a good quality pair of socks. I use Smartwool – they’re great quality and last an entire season.

Puffer Jacket

A puffer jacket acts as your warm layer. I use the hoodless Columbia Women’s Heavenly Jacket (men’s version). Alternatively you can use a fleece zip – I have this one (men’s version) from Columbia. Both of these options are perfect layers to keep you warm on windy, cold, or high elevation hikes.

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!

Bertha Lake Campground

You’ll notice the Bertha Lake campground as soon as you arrive at the Bertha Lake. If you plan to stay at the Bertha Lake campground, make sure you reserve a site at Waterton’s visitor centre or call (403) 859-5133.

There are 2 day-hikes accessible from the Bertha Lake campground; Bertha Peak and Mount Richard Bennett. I have not done either of these hikes, but I will tell you what I know:

Bertha Peak – is rated as hard. Completing this summit will add an extra 3.2kms and 626m of gain to the Bertha Lake trail I have previously mapped out. From the reviews and descriptions on Alltrails, it sounds like you can expect some scrambling and you will need to be confident with route-finding as the trail is difficult to spot on the way up. However at the top you will be rewarded with 360 degree views of Waterton.

Mount Richard Bennett – there is no actual trail guides I could find for this hike – only a route if I zoomed in on Alltrails and panned around the lake. This hike is accessed from the back of the lake, however I would only attempt this hike if you are very experienced and are up for a crazy adventure.

Tips For A Successful Trip

  • Start early or leave late to avoid the crowds – Bertha Lake is one of the most popular hiking trails in Waterton
  • Hike around the lake to get up close and personal with Waterton’s famous red rock
  • Bring bug repellent
  • Aim to hike this on a warm, sunny day
  • Be bear aware and bring your bear spray
  • Pack the right gear
  • Make it at backpacking trip and stay at the Bertha Lake Campground
