Hike the Sulphur Mountain Trail in Banff Canada – 2023

Sulphur Mountain is a mountain in Banff National Park in the Canadian Rocky Mountains just outside the town of Banff in Alberta, Canada. The mountain gets its name from the two sulfurous hot springs found on the lower slopes and offers a nice hiking route to the summit at 2,281 meters (7,486 feet). The most popular way to the top of Sulphur Mountain is with the Banff Gondola.

From the gondola car, you have a beautiful view of the Canadian Rockies, the Spray & Bow Valleys, Lake Minnewanka, and the Town of Banff. From the Sulphur Mountain summit experience jaw-dropping views of Banff National Park.

The Sulphur Mountain trail is a popular hiking route of moderate difficulty that goes up the mountain, below the gondola and is a free way to the top of this icon of Banff. The trail is a continuous uphill with a series of switchbacks crossing underneath the Banff Gondola. Located mostly between the trees views are limited, but there are some amazing vistas from the open patches that you hit every once in a while and great views from the summit. The trail itself is not too busy, but expect a lot of people at the top that made their way up the mountain in the gondola!

You can also take the gondola up and down or just one way making this beautiful mountain accessible to everyone. There are extensive facilities on top of the mountain; a nice boardwalk, viewpoints, some hiking trails, and even restaurants, and a gift shop. For a caffeine junkie like me, coffee on the top of a summit always puts a smile on my face.

Do a shorter version of the hike by taking the gondola one way or extend your hiking route by walking over the mountain and combining the trail with some other trails to Banff town.

It is a 10-minute drive from town. Park at the gondola or the Upper Hot Springs parking lot. The Banff Gondola parking lot has a lot of space, but it fills up quickly in the season.

The trail is popular for hiking, trail running and snowshoeing and the best time to make your way up the trail is from June through October. Dogs are allowed if on a leash. Hiking the trail alone in October I only saw 2 other hikers, but it was crazy busy at the summit. The beautiful mountain views and a Castle Mountain coffee went down well before continuing down the other side of the mountain.

Trailhead Sulphur Mountain Hike

Sulphur Mountain Trail

In season the Sulphur Mountain trail is a busy trail that is easy to follow and it is a relatively safe route to hike alone because it is so busy. The trail snakes up the mountain with 27 switchbacks going zig-zag up the relatively dense wooded slope ending at the top of the Banff Gondola. It is possible to continue walking at this point. Gaps in the forest allow for some nice views along the trail.

The Sulphur Mountain trail starts out relatively wide and dry, but on the upper slopes, it can have muddy and icy sections, microspikes can come in handy. It is a relatively steep 5.5 km hike up the mountain. The views from the top of the trail across the park are excellent. I will recommend waterproof shoes and bring enough water to make it to the top, there is no water on the way.

In season the trail is busy, but walking up in early October I only saw two other hikers. At the top, it was crazy busy. The views from the top of the surrounding mountains are nice.

Hiking from Banff Gondola to Sanson Peak

The trail links with a boardwalk at the summit. To continue hiking to Sanson Peak walk around the gondola building to the boardwalk and continue on the boardwalk for about 500m until you reach Sanson Peak, at an elevation of 2289 meters. There are some nice views from the boardwalk. There is a Mountain Weather Observatory and a meteorological station called the Sulphur Mountain Cosmic Ray Station National Historic Site at Samson Peak with great views of the Bow Valley, Spray Valley, and the Sundance Canyon.

Sulphur Mountain extended hike – continue to Sundance Canyon and Marsh loop

For a great full-day hike I combined Sulphur Mountain with two other trails. There are not many people that walk down the other side of the mountain, so carry bear spray.

You can walk over Sulphur mountain and combine the trail with walking to Sundance Canyon and the Marsh loop for a total hike of 18 km – my hiking time was 4h 25min, Elevation gain 807m.

After hiking to the top of Sulphur Mountain I had a coffee, explored the boardwalk, Sanson Peak, and walked down the other side. I saw some hikers on the way up, hundreds of people that took the gondola at the top, but on the way down the other side of the mountain I did not see anybody and had the whole mountain to myself, only seeing hikers again on the Sundance canyon trail. Walking in October the mountain was covered in snow, the golden larches were beautiful with a mix of green and golden leaves over the mountain.

It was quick going down the mountain on the other side. The Marsh Loop is a flat 2.8 km trail that encircles a wetland filled with hot springs flowing out of the lower slopes of Sulphur Mountain.

The Sundance Canyon trail starts at the Cave and Basin National Historic Site. This trail provides nice panoramic views of the mountains across the Bow River. Easy, steady climb away from the river, the paved section ends, and the moderately difficult trail loops through a water-filled canyon.

Take the Banff Gondola

You can go up and down Sulphur Mountain with the Banff gondola with great views of the surrounding valleys. The Gondola is nice but is very pricy for a 10-minute Gondola ride. The Banff Gondola is a great activity to do with kids in Banff. Do a shorter hike by hiking up and going down with the gondola.

Banff Gondola Price

The Banff Gondola return price varies from CAD$58 to $65 depending on the time of the day. The price of a ticket is based on projected visitation. Hiking up the mountain and taking the Gondola down is possible at half the price of a return ticket. There is no discount for hiking down, if you would like the take the Banff Gondola up and hike down, you must purchase a full-price ticket.

Sulphur Mountain – The Summit

There are more than just breathtaking views at the top of Sulphur Mountain. All hikers won’t enjoy arriving at such a commercial center at the top of the mountain, but I enjoyed taking a look around, having a coffee, and continuing hiking. If you take the gondola up and down there are some nice facilities to enjoy on top. The upper terminal has a state-of-the-art interpretive center with interesting displays for kids. The multi-sensory Above Banff Theatre let you experience the magnificent Canadian Rockies from the perspective of an eagle. Explore the summit with the Sulphur Mountain boardwalk, the outdoor 360-degree rooftop observation deck, 2 restaurants, a coffee shop, and a gift shop.

Best Season to Hike the Sulphur Mountain Trail

Sulphur Mountain can be hiked all year round. In Summer this trail is very popular with many hikers. There is a waterfall where you can freshen up in summer about 3/4 up the mountain. In winter it is fairly quiet with many gondola users going up the mountain. There is a campfire on the observation deck in winter with a great view. Microspikes and hiking poles will be of great help if the slopes get icy in cold weather. In September when I hiked the trail there were only a handful of other hikers walking up the mountain.

Amazing Hikes in Banff

Banff National Park is an incredible place for hiking enthusiasts and nature lovers, with thousands of kilometers of unreal trails around the towns of Banff and Lake Louise. There are trails ranging from flat easy trails to more challenging trails involving some scrambling. The Tunnel Mountain trail is a nice family-friendly route we enjoyed, walking from Banff town. The Big Beehive trail was a beautiful hike from Lake Louise that is a bit more of a challenging route.
