There are many beautiful waterfalls in the area. This link has a bunch and they vary on the difficulty of the hike you want to do.
This is the perfect waterfall if you want to see one without hiking. It's off the highway and you can walk behind it.
Cute little town 30 minutes from the venue, with shops and a few cafes and restaurants.
Little coffee shop with some pastries and sandwiches.
Good option for breakfast.
Great Mexican food.
Cute little lunch spot.
