I've driven up and down the Overseas Highway in the Florida Keys to Key West and back. The pictures don't really do it justice. Imagine clear, turquoise water on all sides of you as you float down the road...
I've been to cities like Paris and Rome and seen the sights there. Just beautiful cities overall but there are specific scenic attractions like Montmartre and the famous basilica atop the hill or the Trevi Fountain.
I've been to the Pont du Gard in the South of France. A famous Roman aqueduct. Truly a marvel of its time and eternity...
I've been to the Palace of Versailles outside of Paris. The gardens and the palace itself. Incredible.
I've walked the Promenade de Anglais in Nice. So many beautiful buildings and nature and people. And then you can go for a dip in the warm waters with the rocky beaches with no sand... I actually stayed there several nights right on the beach in the heart of the action...
I've also been to Fiji, the remote island country in Oceania. Lots of natural beauty there and aquatic activities such as diving. I specifically stayed on the island of Taveuni while I was there, and one of the things we did there is visit the Tavoro waterfalls.
Anyway, I've been to A LOT of beautiful places around the world and it's really hard to list them all and be really specific but I'm from Boston, lived in Washington, D.C. area and Miami area. Visited London, Paris, Rome, Milan, Amsterdam, Nice, Venice, New York, Los Angeles, San Francisco, Chicago, Austin, Atlanta, Houston, Marseille, Philadelphia, Baltimore, Montpelier, Florence, etc.
