Colima Volcano

The state of Colima, located south of Jalisco, is home to the "Most Dangerous" volcano in Mexico. This is just close enough for a day trip, but far enough away that you never have to listen for strains of "I Lava You Truly" and "Oh, Pumice Me!" if you live in Punta del Burro. Bad volcano jokes aside, here is a map which will give you a vague idea of where it is:

If you don't feel like actually going there, you can do a virtual visit via the webcam of the Universidad de Colima. This is a real-time webcam, so you can even see the trees blowing when there's a breeze.

Colima is the third smallest of the 32 states in Mexico. It's bordered by Jalisco to the north and east, and Michoacán to the southeast. It covers an area of 2,106 square miles (5,455 kilometers), and has a 97.5 mile (157 kilometer) coastline. For all you etymologists, the name "Colima" itself stems from the native Nahuatl "collimaitl" (colli = ancestors or gods, and maitl = domain of). The local mythology says that the Gods look down upon their ancient domain from atop their thrones of fire and ice high above the Valley of Colima.
