As with many hikes in Banff, Larch Valley and Sentinel Pass is a must see. It begins at Moraine Lake which can get quite busy at the parking lot so you'll want to go before 10 in the morning if possible. When the bears are out, it is the law to go up with a group of four or more. My wife and I were just two but we had read that it doesn't take long to find others who are going up. Many people came up to the base but mainly to take a picture of the sign stating that bears are in the area. Lame. We were beginning to doubt that other hikers were going to come but it turned out all right. We probably waited about 10-15 minutes before some nice hikers around our same age range came along. Simone, Eric, their dog Chico, along with their four friends from New Brunswick were nice enough to let us join them. Thankfully they were also about the same speed as us. We did see many groups less than four and even some solo hikers. Naughty.
The hike starts with a series of switchbacks within the treed canopy. After a while you hit a fork in the trail with one route taking you to Eiffel Lake and the other to Larch Valley and then onto Sentinel Pass. Soon after you will hit an alpine meadow area which is huge, and then the larches. I did this in July so the trees were still green but if you do it in the fall, apparently everything turns yellow! When you get past Larch Valley and make your way to Sentinel Pass you see a huge 'Z' shape way off and high up in the distance. We weren't sure if we would have to climb that but yes. The 'Z' is the final switchback before you can be rewarded with the view. In July the higher elevations still had snow, which made it a bit tricky to trek through. In some parts the hike would take you through a very steep mountainside with snow. Thankfully we made it through without mishap and finally made it up the last switchback. At the top there is a 360 degree panoramic view. On one side you have the great view of Paradise Valley. On the other side is Larch Valley where you climbed up, and a view of Valley of Ten Peaks. Unfortunately the day we went was quite cloudy. Obviously it'd be better with clearer skies but it was still enjoyable. We had lunch up there as most people do before making our decent.
I would budget about 5 hours round trip for this hike. Make sure to go in a group of four as they can fine you up to $2000 and carry bear spray. read more
