The easiest put-in is a 200 yards below the US 220 Bridge on river left at a river ford.
The first rapid as you enter a small box canyon is called Landslide and is more impressive looking then difficult. Boaters unfamiliar with this rapid should scout from river right. A river left boat scouting eddy comes and goes according to how severe the last high water affected it.
For boaters going to Big Bend there will be a portage at a low water bridge about 5 miles from the put-in.
A shorter trip can be made by taking out at 'Eagles Rock', a tall rock face pinnacle on River right. It will come into view once you leave the canyon and into flater water. A short acces road will be to your left with room to leave a vehicle. There is also a gated area but if you decide to use the field beyond it, please be mindful to chain the gate.

11 of us ran Landslide at around 350 cfs. It looks intimidating but at this level was fairly straightforward. We had three canoes, an inflatable and seven kayak, all making it through without any swims.

Six of ran this section down to the low water bridge on April 20, 2021. The Landslide rapid is no longer blocked by downed trees. While is is now completely clear, it’s still a good idea to scout it because the narrow slot does have the potential to accumulate wood. We ran it at a low level (240 cfs) it found plenty of water in most of the rapids, with only some minor scraping on some gravel bars.

We ran this section June 6, 2020. The left side run out for landslide rapid is blocked as described below. the right side run out is open and can be run. If you are comfortable running this rapid you should be fine, scout from the usual gravel bar on river left above the rapid. If you come out of your boat the current will push you into the root ball/tree described in the comment below. Nobody in our crew of six paddlers had any trouble making the right line.

We consider this our club run. We usually run it at least 6-10 times a season. Landslide is usually easier than it looks. Everybody in our group has rolled in it and just flushed right through. We always scout it on the left. Stop on the sandbar and walk carefully along left bank. I'ld call it a IV but only because a line too far left will put a new scratch on your helmet. As always...make your own decision. Shoot me an email if you're a solid class III paddler with a bombproof roll, and you'ld like someone to paddle this section with. hugetroll@yahoo.com
