On my way back from Chile to the US, I stumbled across a flight deal with a 12-hour daytime layover in Panama City. Being the opportunist that I am, I took it as a chance to explore — from watching massive ships transit the Panama Canal to wandering through Casco Viejo, all before heading back to the airport. Traveling with just a 25L backpack made it easy to be spontaneous, and this post shares exactly how I spent my solo day in Panama.
