Tammany Trace bike and drunk

Old Rail Brewing in Mandeville was open last time I was in the area.
I bet the Abita Brew Pub is as well

Construction is about to begin on the trace near I-12 (interstate expansion) so you will want to make sure you're either planning to stay North or South of the interstate.

One idea would be park at Koop Drive and ride North (stop at Chafunkta Brewery) and head to Abita and Downtown Covington, then back.

If you're going to stay south you're better parking at the Mandeville trailhead and just sticking around Old Mandeville

If you just want breweries yes but it is alot more mileage/riding. From Koop Dr to Abita is over 4 miles and to covington, closer to 6.

The Old Mandeville area has plenty of stops that offer outdoor seating, food, beer and cocktails (Reigers, Grapeful Ape, Barley Oak, Old Rail, Rusty Pelican, Lakehouse, etc) but are located much closer together so just kind of depends what you're looking for.
