This is a small state park with two loops, one with and one without electric hookups. Sites have fire rings and picnic tables. There is a dump station available. Sites are level, in a loop around the bath house. There are also a few cabins available to rent. There's a small $1 surcharge for out of state campers.
For kids, there’s a simple swingset in the loop and a larger, newer playground. Firewood available.
Martinak and Tuckahoe are sister parks, about 20 minutes apart. Tuckahoe offers a number of additional activities, including disc golf, mountain biking, fishing, swimming, and boating(canoe/kayak rentals available). If you’re looking to learn and explore with your kids, there is an extensive junior ranger program.
August 1, 2021, the boat ramp will close for a year; that will likely diminish the appeal of this park for those who want to get out on the river for fishing or boating. When open, there is a network of river trails accessible from the park. There’s a boat launch in nearby West Denton or also at Tuckahoe and a few other nearby spots.
Denton is also your destination if you've forgotten anything.
