With great opportunities for wildlife spotting, this easy Bolsa Chica Ecological Reserve hike takes you on a scenic loop through the 1,300+ acres of protected wetlands just minutes from the Huntington Beach. The scenery includes seabird nesting islands, fresh and saltwater marsh, mudflats, active riparian river banks, and water. Over 200 species of birds have been spotted here, and it’s a popular stopover on bird migration routes. The hike is great for families with opportunities to shorten the route if 4.5 miles is too long.

Getting to Bolsa Chica Ecological Reserve

The hike starts at the north parking area of Bolsa Chica Ecological Reserve, which is easier to get to from all directions. There is also a south parking area, but you can only access it when going north on the Pacific Coast Highway. Make sure you have the right parking area in your GPS.

If the lot is full, there are a few parking lots across the street. I’m not telling you to park there because they’re for the folks that use the stores there, but just so you know…

The park is open from 6am to 8pm. I recommend getting there as close to 6am as you can to secure a spot and see the most wildlife.
Bolsa Chica Hike Directions 6
There’s a decent amount of parking but it fills up quickly.
Bolsa Chica Hike Directions 3
The bathroom has porta-potties. There are also porta-potties about half-way into the hike.

Stop into the interpretive center for a visit if it’s open. The people who work here are very friendly and love sharing their love of Bolsa Chica.

Gear For the Hike

None of the trails here are rough or hardcore, it’s all very smooth and easy. You can do this hike in fitness gear or even jeans in a pinch. If you do the hike around midday it can get hot, there is no shade on the hike. Bring lots of water if that’s the case. There are no drinking fountains.

Here’s the gear that I personally use, have tested, and recommend for this hike.See All of My Best Gear Picks Here

How Will You Navigate the Hike?

I recommend using a combination of paper maps, GPS, and a guide to navigate the hike. If you are tempted to just use a smartphone, please don’t. You’ll often loose cell phone reception on the trail. At the very least, print out a paper map and this guide. Better yet, check out the navigation section on my gear picks page to see the latest and greatest that I’m using. There’s even a special discount on GaiaGPS premium for HikingGuy users.

The Bolsa Chica Ecological Reserve has an interesting history that’s worth briefly understanding about before you hike the trails.

Wildlife of Bolsa Chica Ecological Reserve

There are over 200 species of wildlife that you can find in the park. In general, you can expect to see lots of ducks and waterfowl, shorebirds, herons and egrets, hawks, owls, lizards, and maybe a rabbit. Keep your eyes open for the endangered western snowy plover and California least tern. You’ll also probably see birdwatchers with their massive thousand dollar lenses. Pay attention to where they’re pointing their cameras, there’s probably something worth seeing there.

You might find that rabbits are not scared of humans. When you’re around them, they are generally safe from hawks and raptors, who are scared of you.
Bolsa Chica Hike Directions 25

Bolsa Chica Hike Directions 39
It’s important to stay on the marked trails, even if you see another trail not listed on the official map. The Bolsa Chica Conservancy is actively restoring habits within the park. You wouldn’t want to step on a burrowing owl, which is fairly common in the park and found on the ground.

It’s not uncommon to see more animal footprints that human.

Turn By Turn Directions

Bolsa Chica Hike Directions 7
Start the hike on the well-marked trail at the end of the parking lot.
Bolsa Chica Hike Directions 8
Cross over the bridge to the other side of Bolsa Chica Outer Bay. Don’t forget to look down in the water for stingrays, sharks, shovelnose guitarfish, crabs, and all kinds of other fish.
Bolsa Chica Hike Directions 9
You’ll get some nice sweeping views of the Outer Bay from the middle of the bridge.
Bolsa Chica Hike Directions 10
Once across the bridge, follow the Mesa Trail along the Bolsa Chica Outer Bay.
Bolsa Chica Hike Directions 11
The Mesa Trail is easy to follow, just keep going straight.
Bolsa Chica Hike Directions 12
There are a couple of small cutoffs from the Mesa Trail with scenic overlooks. If the tide is low, you’ll see mud flats with lots of foraging shorebirds. If it’s high, the incoming tide brings fish and wildlife in that in turn attracts predators like raptors and sometimes even a sea lion or two. Check them out and return back to the Mesa Trail.
Bolsa Chica Hike Directions 15
On the left side as you head down the Mesa Trail are native plant and bird nesting areas. This is an active habitat restoration area where volunteers are planting native species and removing invasive ones. Many of the native species survive from the water found in the morning fog.
Bolsa Chica Hike Directions 16
At the split, bear to the right.
Bolsa Chica Hike Directions 17
Keep your eyes open for the remains of a few WW2 gun emplacements. After Pearl Harbor in 1941, the Army constructed 155mm gun emplacements here to protect the Port of Los Angeles. The guns were massive and could shoot up to 26 miles. You can read all about them here. From 1941-1945 this area was known as the Bolsa Chica Military Reservation.
Bolsa Chica Hike Directions 19
Keep hiking to the second overlook area by the gun emplacement. There are good interpretive displays here.
Bolsa Chica Hike Directions 20
From the last overlook, head down the stairs to the big trail junction.
Bolsa Chica Hike Directions 22
At the bottom of the stairs head across the paved bridge over the tide gate.
Bolsa Chica Hike Directions 24
The water bottlenecks through the tide gates, and the abundance of marine life here means that you’ll usually see some birds hunting.
Bolsa Chica Hike Directions 23
Keep going straight across the bridge until you reach the PCH highway.
Bolsa Chica Hike Directions 27
Bear left onto the trail the goes between the PCH and Bolsa Chica Inner Bay. This is the Inner Bay Loop Trail.

Bolsa Chica Hike Directions 35
Merge onto the trail along the East Garden Grove-Wintersburg (EGGW) Flood Control Channel on the left hand side of the trail. Build in the 1960s, the EGGW Channel drains the floodwaters from inland environs such as Santa Ana, Orange, and Anaheim.
Bolsa Chica Hike Directions 36
The path heads between the EGGW Channel and the full tidal basin to the right. The tidal basin connects with the ocean at the Bolsa Chica Inlet, which was re-opened in 2006 after being closed by silting and development. Since then the basin has become the home to over 50 species of fish and 22 endangered and sensitive species of plants and animals.
Bolsa Chica Hike Directions 37
When you reach the bridge over the EGGW Channel, make the left and go over it.
Bolsa Chica Hike Directions 38
Once over the bridge, make the left turn and head back along the other side of the EGGW Channel. There were once trails open straight ahead that connected with the Pocket Loop Trail, but they are now closed to protect bird nesting areas (such as the burrowing owl). Please respect the rules and stay on the official trails.
Bolsa Chica Hike Directions 40
Head back down the other side of the channel.
Bolsa Chica Hike Directions 41
At the end of the path you’ll reach the big intersection that you came through earlier. Make the right and head back to the Mesa Trail.
Bolsa Chica Hike Directions 42
Follow the Mesa Trail back the way you came at the beginning of the hike.
Bolsa Chica Hike Directions 43
Soon you’ll reach the footbridge and your car. That’s the hike! Hope you had fun!
