Here are photos from 3 of the parks that I have visited. Vivaldi Park, Sonata Park and Pucinni Park are all connected by Seven Hills Trail. This trail is a 2.5 loop trail, but there are side trails that take you through the surrounding neighborhoods. All of the trails seem to be paved. The All Trails web site says the trail is good for all levels, but I have learned quickly that even the ease of any path depends on your stamina. Keep a bottle of water with you. To get to Seven Hills Trail and all three parks take the St. Rose Parkway to Seven Hills Trail Drive. Stay on Seven Hills Drive. You will see the entrance to Vivaldi Park on your right. Continuing on you will find Sonata Park on your left, and finally Pucinni Park is on your right just before Seven Hills Trail Drive ends in a "T" with itself. It seems that almost 3/5 of Seven Hills Trail slopes fairly gently upward, 1/5 of the trail is a steep climb, and 1/5 is that downward slope that you always wanted to ride your bike down when you was a kid, so hang on and go for it.
One last item: You can start your walks at any of the three parks. They are all interconnected. And, you can do what I have done by taking 3 separate days to visit three separate parks. I now plan to return to these parks and start taking the trails that extend out through the surrounding neighborhoods.
This scene is from the adjoining neighborhood to the east of Vivaldi Park. I clicked this photo as I exited the site on my way home. The park has fantastic views of the city of Las Vegas, Henderson Executive Airport, and the mountains that surround Las Vegas Valley.
Sonata Park would, I think, be the smallest of the 3 parks. It's major points of interest is the large grassy field and this children's park. When the day is done this park is well used by locals of the neighborhood.
This, in the red, is Seven Hills Trail. The greed dot is Pucinni Park. Following the red line to the left of Pucinni Park will eventually take you to Vivaldi Park in the area of the two red dots that are close together. In figure #1 you can see the trail (in red) as it continues southeastward and hooks up with Seven Hillls Trail Drive. This is where the steep hill begins. But, the downhill side is a refreshing walk.
