While Vallarta may offer many opportunities for excursions, arriving there in a steady rain made it difficult to enjoy. We did try to do some shopping, for which there is abundant opportunity, but walking in the rain was no fun on the crowded and narrow sidewalks. Our snorkeling excursion was a real adventure, as we had to walk in the rain to the "Los Muertos Pier", then wait in the rain for a late arrival of the boat, and boat in the rain to Los Arcos. But the snorkel itself was great, with lots of fish and warm water. David the boatman, and Herman the guide were very helpful from Puerto Vallarta Tours.
