Weather in the San Juans (I live here) is not really conducive to great hiking in April. It’s still plenty snowy up in the mountains towards Silverton and in the La Platas, and typically stays that way until May/Juneish. But as Garlic said, it can snow at any time of the year here. We’re currently having mild weather and rain in the Durango valley, so unless we have more snow, it’ll be slush coming down to Durango on the CT and lots and lots of mud. Which makes for not only unpleasant hiking but serious erosion.
I would recommend waiting a few months more if you want to hike this section–you’ll avoid the mud and slush and be at the height of wildflower season–or stay higher up and bring some solid winter gear.
If you do end up in Durango, you should stop in to Carver’s Brewery for a Colorado Trail Nut Brown Ale…so tasty! :cheers
