Architecture buffs, visitors to the city and adventure-seeking perambulators will welcome the news of a brand-new online tour of Austin architecture. Happy Trails, the second self-guided tour from Guide to Austin Architecture, “follows the fascinating, obscure histories of landmarks along the Ann and Roy Butler Hike-and-Bike Trail to trace downtown Austin’s lakefront revitalization over time,” according to the news release. Ingrid Spencer, the executive director of AIA Austin and the Austin Foundation for Architecture, said, “We wanted to share our love for this trail and provide a new experience to Austinites during these strange times. So many landmarks on the trail have incredible stories – from the monumental to the mundane.” The 10.2 mile trail, which has 14 stops, was produced by local architect Bud Franck, with help from The Trail Foundation. Happy Trails debuts today.
