To Get To Rodman Dam head North on hwy 19 past Altoona and keep going past hwy 40. On hwy 19 after 40 you will also pass an intersection on your left (rd 314) keep going straight for approx another 20 minutes and you will pass over a small bridge/swamp keep going and then you will see a large sign on the left that says Rodman Campground, fishing, etc. In the background should be the start of a huge bridge so you want to turn before the bridge. Across the road there is a sign for a “Boy’s Ranch” Turn left at the Rodman campground sign and follow the road down about 3 miles to parking area. Road dead ends into Rodman Pit.
If you pass the sign you will know because you will go over the “barge canal” a huge bridge. If so turn around go over the bridge and make your first right turn coming in that direction (south)
Last time I went to Rodman we rode quite a ways and found a fun sandpit at Eureka Dam. Directions are posted at this link
