Extremely worthwhile detour. Typical Provincial Park campsite right on Marie Louise Lake. Several hiking trails, including to the "Top of the Giant" with spectacular views over Lake Superior. Attention 300-400m high, steep cliffs. From the campsite you can cycle about 6 km to the starting point of the ascent to the Top of the Giant. There is a bike stand there for connection. So you have more time for the ascent / descent. Take water and power bars with you !!!
