Karst Spring Trail is one of our favorite Kananaskis hiking trails, in fact, it’s one of the few Kananaskis hikes we try to make time for each and every year. We love Kananaskis hikes with a payoff, and the Karst Spring hike delivers big-time!
The Karst Spring hike culminates at a small viewing platform against the side of a rock wall along the north face of Mt. Shark. Here you will witness first-hand the incredible power of nature as a huge stream of water appears out of nowhere, gushing from the Mt. Shark rockface at tremendous force. We’ve been to the Karst Springs platform countless times and it never ceases to impress.

This mountain spring flows rapidly downhill next to the trail, creating one of the most beautiful and dramatic cascading waterfalls we’ve seen in the Canadian Rocky Mountains (or anywhere else in the world for that matter).
Note: To get to the “official” Karst Spring Trail, you need to start your hike along the Watridge Lake Trail, which is an easy hike in Kananaskis. After 4 km you’ll turn left at a junction with a nearly unreadable, well-worn trail map. Within a few minutes you’ll arrive at the small, but beautiful Watridge Lake. There is an easily identifiable sign for Karst Springs at the trailhead.
When we use the term “Karst Spring Trail”, we are including the first leg along Watridge Lake trail and the second leg on Karst Spring Trail.
Karst Spring Trail Highlights
Watridge Lake Trail Highlights:
Traditional Banff and Kananaskis hiking trails are narrow, forcing groups of people to walk single file, but the best part of the Watridge Lake Trail is how wide and open it is, making it an excellent hike for groups. This makes Karst Spring a great family hike, team building hike, hike for a stagette party, etc.
The wide-open Watridge Lake trail allows for excellent views of the surrounding mountain peaks.
The small mountain creek running alongside Watridge Lake trail makes it a magnet for Canadian Rocky Mountain wildlife. Seeing the larger mammals is rare but watch and you’ll see evidence of them along the trail. On our most recent hike we saw a pile of wolf scat!
Karst Spring Trail Highlights
The first part of the Karst Spring trail leg is super-fun for kids of all ages. The Karst Spring hiking trail transitions into a narrow single-file wooden walkway through a marsh. Keep your eyes open, this is prime moose habitat!
The marsh is created by the runoff from Karst Spring. The area is noticeably more humid and the forest becomes very lush, with lichen covered trees and a carpet of brilliant-green moss along the ground.
The Karst Spring trail soon meets up with a rapidly running river. The trail starts to climb steeply here alongside the river. The rapid, cascading Karst Spring waterfall becomes is incredibly picturesque. In fact, it’s up there with some of the most beautiful waterfalls we’ve seen anywhere in the world!
And of course, the experience at the top of the Karst Spring hike where the spring water gushes out from the side of Mt. Shark is simply incredible!
Karst Spring Hiking Trail Stats
Distance: The one-way distance of the Karst Spring Trail is 3.2 miles / 5.1km.
Elevation Gain: The first 2.2 miles / 3.5km of the Karst Spring hike is very flat. In fact, this part of the trail is very wide, so if hiking with a group you’ll likely be too busy socializing to notice any of the gentle inclines along the way.
It’s really only the final 0.3 miles / 0.5km before you reach very end of the the Karst Spring trail that you will have any noticeable uphill hiking effort. This very short section is quite steep, but trust us, it’s worth the effort! The elevation gain over this short stretch is 340 feet / 103m.
Difficulty: If it weren’t for the final 0.3 miles, we would rate this hike as “easy”. Karst Spring Trail is a reasonably short hike and it’s flat almost the whole way.
The last 0.3 miles is pretty steep and you’ll likely find yourself breathing hard. It’s for this reason we ultimately give this hike a “moderate” rating.
Duration: It should take a typical adult about 1 hour to reach the end of the Karst Spring trail.
We did the Karst Spring hike with our 3 & 5-year old kids, so we were a bit slower, completing the one-way distance in 1 hour and 40 minutes.

Hiking Karst Spring with Kids
Karst Spring Trail is one of our favorite family-friendly hikes in Kananaskis Country. The wide-open trail at the start is great for family fun while you walk and the powerful waterfall and mountain spring at the end of the Karst Spring hike always impresses the kids!
There are lots of fun spots for kids to play along the Karst Springs hike, including balancing on fallen tree trunks, along the creek-beds, and the wooden walkway. Just keep a close eye on little ones during the steep ascent to the spring – there are no handrails (except for the platform at the top) and the raging waterfall can be a little too close for comfort at times.
We have some great resources for hiking with kids on our Family Can Travel website. Check out our best tips for hiking with kids, the best hiking gear for kids and the 9 Best Hiking Songs for Your Family.
Hiking Karst Spring in Winter
With such an incredible cascading waterfall, it’s no surprise that hiking Karst Spring in winter is a special experience. The spring still flows from the side of Mt. Shark, but at a lower flow rate than in spring/summer. The lower water levels allow the huge fallen trees and rocks to get covered with ice formations and snow. It’s an incredible sight.
Note, that the Watridge Lake Trail (which takes you to the Karst Spring trailhead) becomes a multi-sport trail in winter. Get all the details about Watridge Lake in winter to choose a fun winter sport to get you to the Karst Spring trailhead. This combination makes for a great winter day trip to Kananaskis!
Where to Stop for Lunch or a Break
There are a few good spots to stop for lunch or a break along the way. There are a few picnic tables at the trailhead, but we recommend skipping those due to the better options ahead.
About 75% the way to Watridge Lake there is a slightly hidden bench in a clearing on the right-hand side of the trail. It’s a nice spot to stop and enjoy the surrounding views and to rest your legs before the steep climb to Karst Spring.
There are also a few benches along the steep hiking trail to the spring. The riverside / waterfall scenery makes it a pretty epic place to stop. It’s also much cooler here, making it a good place to stop on a hot summer day. These benches are pretty popular though, so you may not get one.
There are benches on the platform at the very top, but the platform is quite small and on a busy day it wouldn’t be a great spot to stop for lunch as it’d be too crowded.
Karst Spring Trail Safety
Kananaskis Country is bear country. We love bears and would hate for any harm to come to them or you, so please take the time to educate yourself on how to be bear smart before hitting the Kananaskis trails.
Wildlife Safety
When hiking in Kananaskis Country, you are responsible for your own safety. Before hitting the hiking trails we highly recommend you read our 9 Essential Kananaskis Hiking Tips for information about bear safety, trail conditions, wildlife warnings and possible closures.
Karst Spring Trail Logistics
There are port-a-potties at the trailhead.
There are no drinking water facilities, so fill your hydration packs before you leave.
There is no camping or fires allowed in the area. Instead, stay at one of these Kananaskis campgrounds.
Dogs are allowed on-leash.
Mountain bikes are allowed on Watridge Lake Trail, but not on the Karst Spring Trail. Many people ride their bikes to Watridge Lake, then lock them to a tree and hike the very last section of the Karst Spring trail to the spring.

One tip specific to the Karst Spring hike is to bring a jacket, even on a hot sunny day. Once you turn onto the Karst Spring Trail you enter a dense, humid forest. It becomes a lot cooler there. We even saw snow on the ground in June!
