The start of the trail is accurate, and we drove (high clearance 4x4) up to a gate prior to the true trailhead.

Followed what seems to be an old mining/now USFS road all the way up past marshlands (past cairn-designated trail off to the right that shows on this app but is not named) into the basin before realizing we were actually on a local single track trail. Could not find the shown Swamp Canyon trail past this point - The single track turns back toward Ophir Pass and we wanted to go further up the basin to summit the pass and look over to Island Lake. So we bushwhacked up to the point where we ran across the previous cairn-designated trail we’d decided against.

Following this up to the pass, the last mile is loose scree. The scramble up and over the pass is exactly that - take a hard look at it! We spent over an hour getting up and down this short section and while the views are beautiful, it wasn’t exactly safe or designated route. There’s a reason the highlighted Swamp Canyon trail ends well before the summit of the pass!

Overall, beautiful adventure of a morning. Tons of wildflowers, columbine everywhere in the lower meadows, lots of waterfalls and creeks flowing.
