Not a fan of Socal’s brutal heat? Visit Upper Newport Bay Nature Preserve to enjoy a beautiful coastal hike surrounded by white cliffs and amazing sunsets.

The scenic preserve is a 5.2-mile loop hike located in Newport Beach featuring the upper half of Newport Back Bay, but can be easily shortened or elongated to one’s preference. Its low elevation gain and cool temperatures makes it ideal for hikers of all skill levels regardless of the time of year. Its peak beauty, however, is during the spring, when all the flora has re-blossomed.

  • Dogs are allowed but must be leashed
  • The trail is both a loop and out & back
  • Restroom available

Upper Newport Bay Nature Preserve Hike

I began by first hiking the loop portion of the trail called the West Bluff.

However, if you want to save the best views for last, I suggest starting via the out and back and ending with the loop.

Almost immediately you’ll be rewarded with amazing views of the Cleveland National Forest and the wetlands in the foreground.

Although the majority of the loop consists of a dirt trail, a small section requires hopping onto the bike lane, so keep an eye out.

Switch onto the constellation trail to begin looping around. This is where the trail gets more interesting.

If you’re lucky, you may spot the Peregrine Falcon. I got to see it a couple of times during the same hike, so it’s very possible you will too!

The trail doesn’t actually lead you back to the exact location of the parking lot. Rather, it leads you alongside the Santa Ana-Delhi Flood Control Channel and onto a bridge that runs across it.

Once you hop on the bridge, the rest of the hike is via the bike lane until you hit the street Jamboree. From there, switch onto a dirt road that parallels the street and ends at the water’s edge.

Upper Newport Bay Nature Preserve History

I can’t start from the very beginning without briefly mentioning the geological formation of the area. The white cliffs were formed 15 million years ago, while the bay was carved by the Santa River during the Pleistocene Epoch’s glacial era, which ended around 9000 BC.

Everything from mammoths, giant sloths, and bison have been founded in the reserve, which up until 1862, used to flow directly into the Pacific Ocean. Today you can enjoy over 200 species of birds, as well as thousands of plants, fish, and other wildlife, some of which are sadly endangered.

The first sign of human life in the area dates back to sometime around 7000 BC. The Tongva people, also known as Gabrielinos because of their association with the San Gabriel Mission, inhabited the area from 2000 years ago to when the Spanish arrived.

During the Spanish and Mexican eras, the surrounding land was mostly used for grazing by cattle or sheep, or what John Muir referred to as hoofed locusts.

After the annexation of California into the Union, Rancher James Irvine (same guy as the city of Irvine) bought the bay in 1864, and in 1870, the area was used as a bay. Hence the name new port.

The fight to preserve Upper Newport Bay began in the 1960s when concerned citizens successfully managed to protect the 752-acre preserve from developing into a water-skiing area.
