Bouldering area located at the Joinerville boat ramp along the Maquoketa River. Limestone boulders featuring solid rock and fun movement on a variety of boulders. Problems range from vertical highballs to steep, juggy problems and a few tall, proud lines with hard moves on steep limestone.

You can park along the road inside the park. Please park closer to park entrance/approach trail. This will free up parking near the boat ramp for boaters.

The bouldering at Joinerville Park was independently discovered by John Anderson and Troy Davison, each of whom did some early, undocumented first assents in the park. In 2013 the Iowa Climbers’ Coalition approached the Jackson Country Conservation office about bouldering at Joinerville park. We were given the green light to begin bouldering at Joinerville. However, there caveat is that, if it turns into a problem, this could change.

Bolting and roped climbing are not allowed at Joinerville.

Getting There 

Joinerville park is located along the Maquoketa river in Jackson Country. Take Highway 64 west from Maquoketa for 4 miles. Turn right on 123rd Avenue (look for the Joinerville Canoe Access sign) and go 2 miles North on 123rd avenue to the park entrance.

Joinerville Park is open from 6:00 am – 10:30 pm for day use year-round. Camping is allowed by special permit and board approval only.  Contact the Jackson Country conservation office for details.

Has anyone been out here to contest to the quality and if it is worth a two hour drive? I am interested in help development and have helped develop previous areas throughout the country.

So what's the development scene like - is there still more in the area to be developed, or has the potential pretty much already been tapped out?

There's still plenty of unclimbed rock out here.

I had a great day here when I made a day trip here. Can't wait to return to see what has changed! Some big potential here!

Is this area worth the drive from Des Moines? I'll be up there in a couple weeks, and this seems to be the only posted bouldering in the general vicinity. If anyone has other info than what's posted here, I'd love to hear from you!

Drove from Ames last weekend and it was totally worth it.
Note: The access road to the park is not paved (it's about 1 mile from the highway to parking) and is at river level, likely chances of flooding after heavy rains, and it may stay flooded several days after a heavy rain.

Am going to be doing a lot of developing this summer in this area as I will be living in the Quad Cities!

I am looking for help! I have helped develop a good amount of areas in Utah (Joes Valley, Ogden Bouldering) with university friends....

Would love to meet some others out there to help give this area a reputation!!!

Development Update!

Some friends and I went down up to Joinerville last weekend to try and improve access and improve top-outs. We cleared out a significant amount of fallen trees, logs and dead brush from the trail around the boulders and the top-outs. A couple of the descents from up top were thoroughly cleaned up to improve their safety. There are also some primitive trails on top of the boulders now that lead to descents. Try to keep using them so they stay!

As far as route development is concerned, the top-outs of Dip Boulder, Freshman Boulder, Project Boulder(left slab), and the Alcove Boulder were cleaned off. As a result, some previously dangerous highballs are now safe, so come check them out. We need traffic to keep the routes clean.

Hey guys, I'm a Dubuque resident and I've been looking for some places to climb. I have a group of five guys that were thinking of checking this spot out once summer comes around. So what I was wondering is if anybody that's been developing this area will be around that would want to meet up and show us around. Also we would be down to help clear brush or do whatever needs to be done to help with the development of this area.

Devin, if you are still checking this, DM me. Was just there this past weekend, still a bunch of undocumented stuff, I can show you around. We're working on having a trail day later this summer as well. We can make party for sure.

@Unklhefe I'm planning on climbing here sometime late May- I would definitely be down for a trail day to help development and see what's what. You should post a date here once y'all figure out when you want to/can do a trail day.

It's looking like June 3rd will be the official Trail Day event sponsored by the Iowa Climber's Coalition and The Access Fund!

Found a small bamboo brush near the Project Boulder this weekend. If you are missing it and can identify it I'll mail it back to you. Message me on MP and I'll get back to you.
