Thunderegg Creek is a nice, short hike in Kluane, which follows along an old exploration road with open views of the Alsek Valley and surrounding mountains. There is not much elevation gain as you hike through stunted stands of aspen and balsam poplar, ending up near the base of a large cutbank of Thunderegg Creek, which holds the famous 'thundereggs' (the sphere shaped rocks) this area is known for.

Driving Directions

From Haines Junction, continue north on the Alaska Highway for 10.5 km. Take the left immediately before the Bear Creek Lodge. Note there is a Kluane National Park sign 2 km before this turnoff that mentions the Alsek Trail. Follow this road for about 750 m until you reach a large parking area and some Parks Canada signage for the Alsek Trail. This is the parking area and trailhead. Some 4x4 vehicles may continue past this point but creek crossings may be required.

Trail Description

From the trailhead follow the gravel road that leads southwest from the parking lot towards the large expanse of the Alsek Valley. The road starts through a short section of trees and continues through a series of open fields and poplar stands. Follow this main road for 2.5 km until you reach a fork in the road, where a rougher road leads to the northwest. Follow this road for the remaining 4.2 km which travels through an old, broad floodplain with stunted balsam poplar trees. The sightlines are not great in this area with all the low growing trees and shrubs so it is important to make noise so bears can avoid running into you.

The road ends at a large silt cliff with many good picnic spots to choose from. Thunderegg Creek is through the bushes on the left, but the real attraction is the cliffs themselves as they hold the thundereggs, which are also laying strewn around the base. The views from the cliffs are beautiful looking over the Alsek Valley, Auriol Range and Mount Archibald. Please do not take thundereggs home with you as souvenirs, so that everyone who visits this place in the future can enjoy them.


Note: Overnight trips in Kluane National Park and Reserve require registration and approved bear resistant food canisters. Please visit the Park's website for details.

Did the Thunderegg Creek Trail July 24, 2016 and found the initial creek crossing, about 1 km down the trail, very different than when I was there in fall 2015. Last year there was a board used to cross this creek, however, the creek was now flooded with no easy way to cross. We removed boots and carefully forded the very cold creek. Upon reaching the floodplain portion of the hike we discovered water flowing through, where none had been last fall. We stuck to the right side of the water heading up and managed to find the trail again fairly easily after passing the floodplain.

Skied Thunderegg Trail on March 18 with about 5 cm of fresh snow on the tracks. Trail is flat till the turnoff to the Alsek River, then slightly uphill. We had lunch at the end of the trail, close to the river which was not frozen. It took us 1,5 hr. to ski up to the river and 1 hr. to ski back down. Due to low temps the snow was sticky in lower elevations. Scenery is great with changing vegetation, views were limited since it was snowing most of the day.
GREAT trip for an easy day on x-country skies!

On August 16th a small group of us went out on this trail, on a glorious late summer day. My five year old grandson was one of the group, plus other family members. We made it all the way to the Thunder eggs at the end of the trail, which was a source of amazement to us all, especially my grandson, who later declared this to be the best day of his life. The trail is essentially a gravelled road all the way, and hence very easy to follow. The scenery is intoxicating, and why I've never done this hike before in my 35 years in the Yukon is a mystery. This is totally recommended to everyone, of all ages, as our hike proved. It ranks among the very best day-out hikes I've ever been on.
