Inland Rail Trail

Part of trail is good for cycling.

August, 2022 by 8520258intel

The end section in San Marcos is quite good, the part along Mission Ave. in Escondido is OK. But in between the cities are a number of locations where tree roots have severely damaged the asphalt, some in shadow area surprising you when you hit them with your bike. So if coming from Escondido by bike I take Rancheros Dr. down to Woodland Pkwy, take a right and then a left on Mission Ave all the way to Twin Oaks Valley RD and get back on trail there. This is to bypass the poor section of trail.

Bayshore Bikeway

ok if you’re in the area

August, 2022 by mulroneykl

I did the entire loop yesterday to train while I was in San Diego. It is paved, so that’s a good thing (for me!) but frankly it’s just not as scenic as advertised and there are sections that are just industrial and ugly. So much trash along sections and the onroad portion on the San Diego side of the bay is terrible. On the more scenic side, you are mostly riding next to a high-speed road so it’s noisy. Can’t really ride along the San Diego side once you get to the crowds - or at least go very slowly. (Same right near Coronado but that thins out quickly.) Bottom like is that it’s worth checking out if you are here, but not something to travel a distance for. I managed to do ~30 miles by adding a loop around Coronado and going out and back on the Sweetwater Bikeway.

San Diego River Trail

Dirty and be careful

If you're with a group of guys you should be 'ok'. SD River Trail homeless encampments has grown and grown and that means ton of trash and possible not so good encounters.

San Luis Rey River Trail

Nice bike path

May, 2022 by mark0053

This was my 3rd time doing this path. I always park at the easternmost entrance to the trail. There is a gravel parking lot there and in a good area to leave you car. I really like this path because it does not follow any highways or cross any busy intersections. You feel totally safe riding on this path. No homeless encampments etc. to deal with just nice nature. When riding from east to west I have always encountered a strong headwind. You ride along what used to be the San Luis River, long such dried up but there are many areas of interesting sites. Going from east to west you end up in Oceanside and only a few blocks from the ocean walkway. All in all this is one of my favorite bike paths. Well maintained, safe, flat, and just the right mileage for me. One note: Aprox 1 mile from the easternmost path entrance you do travel through a residential neighborhood. It is NOT well marked which way to go. As soon as you enter the neighborhood turn RIGHT on the street and go to the end of that block where you turn left for about a block. Look for a sign that points to the re-entrance to the bike path on your right.

State Route 56 Bike Path

Nice ride but noisy

May, 2022 by mark0053

I had the chance to do 2 bike paths in 2 days that were close by. This was my first time on the State Rt. 56 path. I started from the east end and parked in the parking lot at the Carmel Mt. Ranch Community Park. The parking was free and I felt in a good area that was secure to leave my car at. To access the beginning of the path however was a bit of a job. You have to bike down the street and turn right to access the trail. The first time I rode past the entrance and had to circle back. As bike paths go this one is just o.k.. The path is well maintained but does cross several streets with crosswalks. At one point not too far after starting you come to an intersection that is NOT well marked for the bike path. After some looking around I finally noticed the path sign diagonally across a big intersection. There are areas of the path that are very nice and quiet but for the most part it's a noisy bike ride along the freeway.

So many street crossings, it was frustrating. Not worth the time.

Went here today and honestly it wasn't bad. Large cracks in the path were a bit of a pain but it's not a major issue.. I fell 3 times but I was going backwards and not paying attention so thats all on me.

January, 2022 by smariej72100

It was a pretty ride. Lots of walking traffic along the way, so if you’re riding a bike you have to be extra cautious.

Rose Canyon Trail

December, 2021 by joanmbain

This trail leans to another trail and another. Each time we thought we were at the end, we weren't. Finally it opened up into the Mission Bay Bike Path which makes it a really long trail, taking you from La Jolla to Mission Bay without ever encountering car traffic. We LOVED it!!

San Diego River Trail

The trail is all you get. Overgrown bushes block the scene of the river. Lots of trash. Sectioned off by the city roads.
