Don't miss out on a hike up the canyon. You have to wade through the river at points, but it's an amazing place and a fun hike.
"The Narrows"
I went through there in 09 with my Harley from the east entrance, I looked for an entrance from the south to the east and I couldn't find one. What are you referring to Jelag? The only way through is from the east to west or the west to east. And there is a clearance issue with the tunnels from what I remember, but they had the pavement tore up and a good stretch of the road was dirt, BTW a little hairy with a Harley at the GVWR.
