Multiple tees on several holes. This course has some good lines and you will need a variety of shots to be able to score well here.
The grass is green, lush, and mowed nicely.
Two Rivers has a good variety of holes and a good mix of length as short, moderate, and longer holes are all present.
The views of the 2 rivers adds a nice scenic touch.
Hole 6 is a long par 5 depending on which tee you choose and it also has multiple basket locations, one of which is elevated which adds a nice touch of difficulty.
Hole 7's long pad uses the elevation(what little is here)well. Make sure you don't go in the rough on the right hand side of the fairway as its very hard to pitch out and get your par.
This is a park style course and there are a couple of layouts to choose from, 18 or 21 holes are present.

The course is split into 2 halves and you have to walk across the parking lot from 9's basket to get to 10's tee pad. While this isn't a huge issue, it does slow the flow of the round down a bit.
Holes 14 and 15 play close to the road, so when its windy that could be a factor. Please make sure it's clear before you throw.

Two Rivers is more flat and more "refined" than it's sister course Columbia Park across town. This course is what park style disc golf is about, well kept and good lines.
I like the fact that the river is close to the course, it adds just the right amount of pucker factor to the holes, but doesn't come into play per se on the 18 hole layout. The OB railing on 14 and 15 makes those 2 holes play that much more difficult, so get your birdies early.
This is a fun course and it pairs well with the above mentioned Columbia Park.
If you are looking for 2 very good courses in SE Washington area then Kennewick has your back.

Very well kept and very new! You will be walking on level grass all day so there is no need to wear "roughing it" foot wear like Columbia Park. If you want to work on your driving game this is the place for you! #6 is a crushing 802ft. Some jerks took the signs that were at each tee pad. Thank goodness that the people who run the park did not let the few wreck it for the rest of us. They have replaced the signs. KUDOS TO YOU GUYS!!!

Like most have posted the water is a black hole and I lost a disc into the Columbia river at #12. #13 can be another disc eater. The back 9 is a total teeth grinding event. You want to just chuck the heck out your disc but you have to hold back due to the river and the road being so close.

Love the Tee pads! After a good round, a lost disc and temper I'd say this is a great course to play and see. I'd also highly recommend that if you do play this course that you do it in the AM as you are in a big park and people are all over having BBQ's. On the 1st run right off the tee we were throwing right at a family eating. No way around it but to play it safe and short our shots. If you beat the BBQ'ers it is wide open. Maps of the course are located on the side of the park office (trailer).
This web page shows that #15 has a pro shot of 820ft but the local map only shows one tee to #15 at 628ft. If you look up on the trees they have bolted arrow signs to mark where your fairway is.
