You can take a short hike, or a long challenging hike to the very place the flood started (Lawn Lake, nestled below gorgeous peaks). A park ranger is usually around to tell stories and answer questions. It is fascinating to see this area up co0se...and...More

When we first arrived here, it looked like they tore the waterfall and stream all out because of the floods. We couldn't see the waterfall, the bridge was gone and there was just a small stream among large boulders and a rocky parking lot. Nothing...More

I was able to climb halfway up. Great view from up there. I’d never seen in person an alluvial fan. Worth the side trip.

We had no idea what an alluvial fan was until we saw it. Very interesting and well worth the hike. We liked it so much we actually hiked from both parking lots and did a great rock scramble to get closer to the top. I...More

All it is is a load of boulders washed down the river in a flood some years ago which are all scattered on the river banks. Unless you are passing on the 34 /36 circular road trip I would not bother to go especially otherwise.

This is near the top of the two way portion of the Old Fall River road. This is the remains of an earthen dam that broke with a boom 40 years ago. Great Little Rock scramble and a modest water falls.

If you are interested in a short walk to an interesting view of historical mountain flood plain this is great. In 1982 an earthen dam broke holding an alpine lake, flooding the area and killing a couple of campers down stream and into Estes Park....More

Alluvial Fan is the product of a flood in 1982 which resulted when an earthen dam built in the 30's failed. The gorge and waterfall attest to the incredible power of water. That flood even changed the course of Roaring Creek. Then in 2013, a...More

Hiking next to flowing water on the rocks is the best! Granted this isn't one of your more difficult hikes that take you to lakes, but this was a good, short morning excursion for us instead of going to an overcrowded Bear Lake/Emerald Lake trail...More

The Alluvial fan is a great spot to scamble over some rocks, play in the stream or just take some pictures. A short hike from the parking lot will get you to a an overlook area and from there many adventures await.

If you enter the Fall River Entrance to RMNP, the Alluvial Fan is about 3 miles from this entrance. You will see the right hand turn off highway 34 onto Endovalley Road. There is a sign. You can download the official RMNP... More
