Many homeless people living along the path. High brush and garbage, tunnel made me nervous. Then, it continued down the side of a road. Not interested in walking with cars.
Standing on its own, this is an enjoyable walk or ride to experience San Diego beach culture. However, you really should consider combining it with the Mission Bay Bike Path to make it great (see my March 2019 review of the Mission Beach Bike Path for my customized directions)!
Be sure to go all the way up to the bluff just beyond the north end of the path to Palisades Park for spectacular views.
A part of this trail can be congested with pedestrians at times, but the cool breezes, sunny sky, and beautiful sights make it worth your time! Take it slow, live for the moment, and say to yourself, "Life is good!"
This is one of our favorite rides. Every time we travel south to San Diego, we make a point of riding this trail. We've only ridden it on summer weekdays, so bike and pedestrian traffic wasn't an issue (unless you decide to combine this with the Mission Beach-Pacific Beach Boardwalk which we always do). This path is outstanding for its wide concrete trail, amazing views, cool ocean breeze, flatness (except for a couple of bridges), and for being a loop!
We don't follow the Rails-To-Trails Mission Bay Bike Path map to the letter. We think our customized route is better, so consider trying our directions. Unless we're staying in a Mission Beach rental home, we like to park at the north end of Mission Bay at De Anza Cove Park, then hop on the trail there and proceed in a clockwise manner. As we approach South Shores Parkway, near Sea World, we continue across it and stay on the path which hugs and encircles the Sea World parking lot. Eventually you'll head north on Ingraham Street to the first bridge which goes over the bay to Vacation Isle. Just stay on the bridge's sidewalk so you don't have to worry about a couple of tons of metal running you down. You'll have to go over one more short bridge over Fisherman's Channel, then you hop back on the Mission Bay trail heading west. This is my favorite part since you're totally away from roads and there is very little bike or pedestrian traffic. Plus it's the prettiest part of the loop! Million dollar homes and million dollar views of Mission Bay! Stay on this path and you'll eventually curve south along the bay.
When you get to West Mission Bay Drive, continue across it through Bonita Cove Park on a bike/pedestrian trail that will lead you past more beautiful bay front homes down to Mission Point Park. This is a great spot to find a bench, take in the incredible views, have a snacky, and perhaps use the restroom.
After you've had your fill of gorgeous scenery, head west on San Diego Place and then North Jetty Road. You'll soon discover the trailhead for the Ocean Front Walk, or Mission Beach-Pacific Beach Boardwalk. It's quiet and lovely down at that end as you ride between multi-million dollar homes and the sand. Eventually it will become somewhat congested with pedestrians as you encounter the restaurants, businesses, and tourist attractions, but that's OK. Just take it slow and enjoy the culture of Mission Beach!
Once you get past the pier it will open up a bit. Toward the end of the boardwalk, go up a short incline to a bluff and Palisades Park. What a great photo op as you look back down the coast toward the jetty where you started northward.
After your moment of zen, head back down the boardwalk, and when you reach San Rafael Place cut through all of the homes between the ocean and bay to get back on the Mission Bay Bike Path.
Now you can continue your loop, eventually passing Crown Point Park and a wildlife preserve on your way back to De Anza Cove Park.
This has to be one of the all-time great southern California beach rides. It's meant to be taken slowly, so relax and savor it. Don't forget your sunscreen!
I suspect this trail is especially popular with the surrounding community. I know if I lived there I'd be cruising down to the beach every day on it! For a couple of out of towners, it was well worth the time we put into exploring it.
After spending the night in Dana Point's bluff hugging Blue Lantern Inn, we parked the car and unloaded the bikes in Dana Point Marina's Baby Beach parking lot so we could enjoy pedaling around the quiet marina streets as well as the San Juan Creek Trail.
After cruising over to Doheny State Beach to the trailhead, we began our trek along the bank of the creek. For the most part it's a nice, fairly quiet ride. On the way up, we took a detour and explored the Trabuco Creek Trail as well as Old Historic San Juan Capistrano.
The San Juan Creek Trail eventually concluded in a somewhat rural area of ranches and equestrian centers. After cruising back down to the trailhead, I must say it's pretty cool to relax on the beach in the cool, salty air and to bask in the sun.
Nice bikeway, especially once you get out of the city and neighborhoods. A bit steep toward the end, but at least it's downhill most of the way back!
An OK ride. Not especially exciting, but it is easy and flat. The best part is extending the ride to The Strand in order to ride alongside the beach. Consider heading to the pier and Ruby's Diner.
We've ridden the two segments in Oceanside. The segments are nice and plenty wide enough. Any trail that gets you away from traffic is a much more enjoyable experience than the narrow city streets here. The main issue is the segments are so short and disjointed. Once the entire section through Oceanside is completed, it will be a great boon to residents and tourism. Once the trail from Oceanside to San Diego is completed it will be a biker's mecca. Given how dense the coastal cities are here I can't see this ever happening in my lifetime unless the railroad is willing to create an easement along the tracks.
This trail has some rest areas near the eastern terminus. The best-looking one IMO is west of the East Yale Loop exit.
Despite Wikipedia: The San Diego Creek bicycle path connects major points such as Newport Beach, University of California, Irvine, Boomers, Colonel Bill Barber Park, Irvine Civic Center, The Crossroads Shopping Center, Woodbridge High School, Woodbridge Community Park, Atria Senior Residential Area, Windrow Community Park, Irvine Medical Complex, and ultimately, Irvine Spectrum Center.
The trail actually ends at the 133 toll road. East of the Alton Parkway exit there's just a lonely mile with no exits and a guardrail at the end. At least the Alton Parkway exit is only 1 mile west of the Irvine Spectrum Center, so you're not on Alton Parkway EastBound for too long.
Most of the route goes through scenic areas, both marshy and through Coronado. Sure, there’s some industrial parts and can be hefty headwinds but it’s an overall nice ride.
My wife, Kindred, and I did the trail staring at the ferry and going clockwise around for a 25.09 mile ride, including the ferry trip back across the bay. A perfect day to ride even though there was a little wind! Highly recommend doing this lovely bike ride. 3/30/2018
