    The Castle Towers Backpacking Trail is a difficult 34.6 km out-and-back hiking route that climbs through the rugged landscape of Garibaldi Provincial Park on the way to summit Castle Towers. This trail is best completed in a multi-day format, with an overnight stay at the Helm Creek Campground. Along the trail you will hike through scenic alpine meadows and experience the amazing sights within the park, such as the iconic Black Tusk and numerous glaciers. This is a challenging route that should only be attempted by experienced and confident hikers, but it does offer fantastic views that will allow you to witness the natural beauty of the Whistler area.

    Route Description for Castle Towers Backpacking Trail

    The Castle Towers Backpacking Trail is a difficult multi-day hiking route that requires hikers to have a good level of fitness, experience, and confidence to complete the summit of Castle Towers. Portions of the route are unmarked and will require navigation using a GPS if you are unfamiliar with the route. Additionally, the upper part of the trail along Polemonium Ridge and the final ascent of Castle Towers will require a good deal of scrambling in order to traverse the rocky terrain. Make sure to wear sturdy hiking footwear and bring any necessary gear, such as crampons or microspikes in order to traverse this technical terrain.

    Although the route is a difficult one, it also provides the opportunity to witness some of the most amazing landscapes in the Whistler area. From stunning views of Black Tusk and Mount Garibaldi to beautiful alpine meadows and chilly glaciers; this hiking route has a truly diverse landscape that will leave you in awe.

    Day 1: From Trailhead to Helm Creek Campground

    Setting out from the trailhead, follow the trail as it heads east through the forest for 1.7km, where you will come to a junction in the trail. Take the path to the right to cross over the rushing waters of the Cheakamus River and follow along a series of switchbacks that climb uphill. The trail will continue on through the dense forests of Garibaldi Provincial Park for 6km, at which point you will enter into beautiful alpine meadows at the Helm Creek Campground. After setting up camp, take the opportunity to explore the area and take in the spectacular views of the alpine landscape and nearby Black Tusk before settling in to rest overnight for the ascent of Castle Towers the following day.

    Helm Creek Campground

    The Helm Creek Campground is a perfect spot to set up camp if you are looking to hike the many trails that can be found in this part of Garibaldi Provincial Park, including Panorama Ridge, Black Tusk and Garibaldi Lake. The campsite offers 30 tent pads that require a pre-booked reservation to utilize, and also contains outhouses and bear caches to safely store your food. The scenery around the campsite is spectacular, providing views over the rugged landscape in all directions.

    • It costs $6 per tent pad/night

    Day 2: From Helm Creek Campground to Castle Towers and return journey

    After breaking camp, leave the beauty of the meadow behind you and set out on a path to the south that will pass through the forest and cross over several streams. After roughly 1km, you will need to break off from the trail on an unmarked route that will take you around the edge of Helm Glacier. You will need a GPS to tackle this part of the trail, so keep an eye on the route in order to stay on the correct course towards Castle Towers.

    Eventually, the route will bring you to an east-west moraine that you will need to work around to continue along the trail. Climb up onto the ridge of the moraine and follow the GPS as it leads you along the ridgeline. This route will lead you around the edge of Helm Glacier in a southeast direction toward your final destination of Castle Towers. Although the glacier is accessible, do not attempt to climb across it unless you are familiar with glacier hiking and have a wealth of experience. Melt holes and crevasses represent a real danger to amateur hikers and should be taken seriously.

    Working along the Polemonium Ridge, continue on in a southeastern direction as you scramble across the rocky terrain towards the summit of Castle Towers. This portion of the trail is littered with fields of small boulders, making the terrain a technical and slow-going affair. After making the final climb up to the summit, hikers will be rewarded with amazingly scenic views that stretch out in all directions over Garibaldi Provincial Park. Countless mountain peaks and icy glaciers can be seen from this vantage point, including Mount Garibaldi, The Sphinx and even Mount Tantalus to the southwest. After taking in the gorgeous views, carefully work your way back down along the same trail to either return to the campsite or push on to the parking lot having completed the Castle Towers Backpacking Trail.

    The Castle Towers Backpacking Trail passes right through the Helm Creek Campground and offers a bit of flexibility with route planning.
