Start of trail to Sentinel Pass.

Before you go, make sure you pack a hearty snack or a light lunch, make sure you bring some layers of clothes, dogs must be on a leash and don't forget the bear spray. I think you will find the trek up the switch backs to be most grueling section of this trip, so best go prepared. Also, the Larch season is not till the fall, so if anytime you go and see green tree's, you will know its not time yet.

It's also important to note that the Moraine Lake parking lot is full most weekends and unless you have a commercial vehicle, your chances of getting in are slim to none. The parking lot is small due to the demand for the amount of people that want to go there. Moraine Lake is the most popular destination in the Banff National Park, if you go there you will see why it is one of the most beautiful places in the world. They also have the road barricaded, and it is manned by several park employees from 6:00am - 7:00pm. Now, you are free to go up when it is outside of those times, but you could be facing congestion, parking on the side of the road and you could be even trapped for a few hours while the traffic dissipates.

Map to Sentinel Pass.

When you head out from the Moraine Lake parking lot, you will walk by the Moraine Lake Lodge where you can stop in and grab a coffee. Once you had your coffee, you will walk around the lake shore till you get to the boat launch. Here, you will make a right and take the trial to Sentinel Pass. Right, always keep right. There are some other trails further up that will take you to Eiffel Lake and Eiffel Tower respectively, however they are well marked and you should not have any problem.

Larch Valley.

Once you get a little ways in, you will notice a gradual climb this is you prelude to the switch backs. Once at the switch backs, this is the most grueling part, there is not much of a view because you are in the forest, but you will have a nice view of Moraine Lake once you come to one of the logged out sections. This is a great opportunity to take a break and get a couple of pictures.

Pinnacle Mountain.

Once you get past the switch backs you will be treated with wonderful views of Larch tree's and peace of mind knowing the hard part is over. At this point you will be presented with a sign that marks the way to Eiffel Lakes, remember to stay to the right.

Larch Valley.

Walking through Larch Valley you cant help but wonder how all these Larch tree's are congregated in one place. Perhaps, it's something in the environment or that is unique to the area that gives the tree's a heads up on the competition.

As you come to the end of Larch Valley, you will arrive at the Minnestimma Lake's. This where you can now see the Sentinel Pass and the switch backs that lead up to it. It's also important to mention that the switch backs that lead up to the pass only take about 10 minutes or so, maybe 15 minutes from Minnestimma Lake.

Once you are at Sentinel Pass you can then see into Paradise Valley. To return, simply retrace your steps all the way back to Moraine Lake. For those looking for a little more, you can continue on through Paradise Valley, you will need 2 cars for this, one at Moraine Lake and another at the Paradise Valley trail head.
