New Botanical Garden of Puerto Vallata
There is an incredible new Botanical Garden (and nursery, restaurant, with a beautiful building for events) about a half hour south of Puerta Vallarta, MX. It is also the location for the PV Orchid Gardener's group, for those interested in orchids.
The website is www.pvbg.net.
This is a must-see. It's not even a year old yet, and it's beautiful. Also, it is set about a small river, with places to swim and cool off.
