Nestled in the community of Newport Beach, the Bluff and Bay Trail Loop in Upper Newport Bay Nature Preserve offers great views of Upper Newport Bay and world-class wildlife spotting. The Upper Newport Bay Nature Preserve is home to some 200 bird species, including some endangered species, making it a top bird watching destination in the USA.

This guide has an easy and fun loop hike that takes you on trails down along the shore of Upper Newport Bay, then back along the bluffs overlooking the bay that offer great views.

What You Need For the Hike

This isn’t a hardcore hike that requires any special gear. The only thing is that the lower trail can be muddy, so good hiking boots or waterproof sneakers would be smart. Here’s what I would take.

My Top Gear Picks

Garmin inreach review

Do you have the right hiking gear? Will it stand up to the test? I waste lots of money testing hiking gear every year so that you don’t have to. My gear picks are solid choices that will serve you well on the trail. I don’t do sponsored or paid reviews, I just the share actual gear that I use all the time that’s made the cut. Here are my top picks:

  1. Garmin InReach Mini Emergency Beacon – Hiking out of cell phone range? Make sure you have one of these two-way satellite texting devices in case your hike doesn’t go as planned. You can read my full review here.
  2. Injinji Sock Liners With Darn Tough Hiking Socks – This combo is a great way to avoid blisters out on the trail. I have some insider-hiking tips for avoiding blisters here. Pair them with modern, high-tech hiking boots (for women and men) and your feet with thank you.
  3. Garmin Fenix 5x Plus – It’s a little pricey, but man do I love this thing. Not only does it have all the topo maps and navigation tools on my wrist, but it also acts as a long battery life, rugged, outdoors version of an Apple Watch. Track your workouts, sleep, heart rate, all that stuff.

I have lots of other great, sponsor-free, trail tested gear picks on my “best gear” page.

Fenix 5x Hiking Review

I highly recommend bringing a good paper map with you, and then using it in conjunction with a GPS device. You can see the navigation gear that I use here (I’m currently using the Fenix 5x Plus and love it). Just download the GPX file below and load it onto your GPS.

Many people also print out this web page for the turn-by-turn images. And if you really want to get tricky, YouTube Premium lets you download videos for offline use, so you can download the hike video and save it.

The hike hugs the Upper Newport Bay shoreline for the first half, and then returns along the bluffs. The hike is mainly flat aside from some minor ups and downs.

There are a lot of twists and turns in these hike directions. If you get lost, don’t sweat it, the park is small and you’ll probably be easy to find your way. You can also pick up a map at the Peter and Mary Muth Interpretive Center, but it only has the main trails on it.

Upper Newport Bay Nature Preserve
The overlook is a cool little area. There are more of these on the way back.
Upper Newport Bay New Entrance
Here’s the start of the trail down the hill. The park put this little fence up recently. I called them to ask if the trail was closed, but no one could answer me. Since it doesn’t say this trail is closed, and there is obviously a way down the trail to the side, I interpret this is “you can hike here, but you need to stay on the trail.” Head down the hill here.

Leave the overlook and head down the second left from the former picture. You’ll hike down some steps toward the shoreline.

You’ll notice so debris and flotsam down here. If there’s a storm surge or unusually high tide, this area might be underwater, in which case you need to turn around and go back. But usually it’s okay. Time your trip for low tide in Newport Bay for the best chances.
