Started at Jensen Nature Park with intent to ride the loop at south end of trail but lots of construction and confusing detours. Returned to Jensen Nature Park and rode north to W 300 N street. Looked like trail ended there, so turned around. My bad for not consulting map and would have seen left turn for short distance and then continue north. Oh well. There is some signage along the trail but only one sign post indicating Old Emigration Trail the remainders have other names for different segments, I guess. Anyway not a clearly marked trail and several places of construction on going. Trail surface was fine and plenty wide enough. Maybe at a later date if back in the area would give it another try.

July 2021 We started at the boat docks and went all the way up and back. The trail is not bad but has a few issues. It is bumpy in places and a few of the tunnels under the roads become so narrow that you will collide if someone is coming the other direction. We quickly learned to pause and yell to see if anyone was already under/inside. You bypass suburban neighborhoods and then follow the Provo River up the beautiful canyon past Bridal Vail Falls and to a small but picturesque park. Overall a fun ride.

Beautiful walking trail. Completed a 20 mile Scout hike with my son's troop.

I started from the north side and rode south until I reached 4400 by riverdale. There are some areas that need maintenance but overall in good shape. Sometimes it’s hard to follow but I used the map on here. My only complaint is the sharp turns that make it hard to see oncoming traffic so I’m hesitant to pick up speed in some areas. It’s great for a casual ride with lots of shade.

A fun short trail. Good for walking or biking with kids. Minor hills. Too crowded and too short for serious biking.

I have biked and run this trail from end to end multiple times. I love that it's easily accessible from my home and I can do any distance. Mostly mild ups and downs; it does have a couple of challenging hills, but that's part of the workout, right? In warm weather you may want to plan for early morning or evening use do to the lack of shade.
I have seen comments that this trail uses the emergency lane on the highway and is dangerous. Not actually true. There IS a designated bike lane on the highway, but I never use it. The separate paved trail runs parallel to the highway, but does switch sides a couple of times. These changes need better signage. Watch for these changes especially at the intersections of 13400 South and also 7800 South. Staying on the separate path is much safer and provides a more scenic and more enjoyable experience.
Side note - I have seen many types of birds, several deer, and a five foot bull snake.

I like this trail, I have ridden it many times in the past, this is the first time this year. Right now there is a detour to the rail trail, looks like the Parkway trail is being paved and 'touched up', nice, thank you! I rode on a week day so not much traffic. Added bonus, there was a young fox on the trail this morning! The only thing I dislike is the diesel fumes from the vehicles on the south end where you are riding right beside the Legacy Highway.

This is really one of the best trails in Utah. The only issue is that it can have heavy use at times. Even then, it’s wide and smooth with great views all around. We’ve cycled the complete trail many times in all seasons and never been disappointed.

Provo River Parkway is a mixed route that is hard to beat. From the lake (but see below) to the babbling river, to quiet residential areas, following an easy track along a main thoroughfare is hard to notice with the spectacular mountains in plain view. It's really quite good. The cherry on top is the ride up the canyon. Five miles of up can sound intimidating, but the grade is mostly low and the route is accessible to adv beginners. The views all along are fantastic, but Bridal Veil Falls and Vivian Park hollow are worth the effort.

I would have given five stars, but the route on the Utah Lake State Park end is still a mess (May 18,2021). The trail is closed at the first two trailheads starting at the lakefront access. We used N Geneva Rd, where the trail is also closed. Basically, everything west of I-15 is hit or miss. Expect unmarked detours. We were able to follow W Center St to Independence and back to the trail. Center St by I-15 looks like a major highway. There is a wide sidewalk just after the underpass that is easy to miss (and of course is not marked).

It's also a little confusing at W 2230 N St. The trail is marked closed. It appears that it will eventually continue along the river. The correct unmarked detour goes along 2230 St for about 1/2 mile. Turn left on the wide walkway at University Ave (Rt 189) and you're on your way to the canyon.

Also, the trail is often marked as three lanes, two for bikes in each direction and one for pedestrians. However, it was common to come around blind corners and encounter runners or walkers in the bike lanes. Be alert.
