If there is anyone out there who still thinks Texas is all flat and dry, a visit to Westcave Preserve would be a certain cure. And even readers of this myth-busting magazine (who already know the Hill Country better than that) will be impressed by the spectacular sights in this cool, sheltered canyon, formed by the gradual collapse of an immense limestone cave in southwestern Travis County – just 40 minutes from downtown Austin.
