We don't normally do "excursions," per se. On our recent visit, we walked the approximately one mile to the Pacifico/Corona brewery, where we were given a very inclusive tour, followed by a beer at the "top of the tower" lounge. They also gave each of us a small momento brochure with our picture included. Cost ..........zero, plus some good exercise. In a prior visit, we just walked to the cathedral for a self-tour, followed by some local window shopping. We saw whales off of Cabo, plus I witnessed a stingray leaping and flipping near the ship.
