Hamilton State Park
RV Guide


Visiting Hamilton State Park is a must, whether you're primitive camping or planning to relax in your RV. The park is also known as Hamilton County State Fish and Wildlife Area, or Dolan Lake. There are many activities to enjoy in the park, as it is home to the 75-acre Dolan Lake. Boating, hiking, horseback riding, fishing, and picnicking are among the most common activities in the park.

Dolan Lake was filled shortly after the dam was built in 1962. There are over three miles of shoreline on the lake, and the maximum depth of the water is 18 feet. This makes fishing both rewarding and challenging where trees and branches can fall.

Hamilton State Park is excellent for camping, whether you're primitive camping or enjoying the luxuries of your RV. There are no water or sewer hookups, but there are electric hookups and a dump station within the park, making it very suitable for your RV or camper trailer.

If you plan to visit in the winter, ice fishing on the lake is permitted when the ice is thick enough. The temperatures in the winter in Illinois can remain below freezing for weeks, making for the perfect ice fishing conditions! As with the majority of the US, summer temperatures range from the upper 70s to the low 90s Fahrenheit.

RV Rentals in Hamilton State Park



Whether you're driving your car or RV, accessing Hamilton County Fish and Wildlife Area is a breeze. The park is not located near any major cities, so you know traffic will be fair or good almost all of the time. In addition to the traffic being lighter due to being far from a major city, the distance from a city will also provide you with an excellent view of the starry night.

There are two main entrances into the park, one being on County Road 1100N, and the other being on County Road 1025N. All of the roads throughout the park are both wide and paved, making it easy to navigate your RV or trailer.

Although the roads are paved and easy to navigate, you may face a challenge if driving your RV to places in the park other than the campground. There is very little parking throughout the park that can accommodate something as large as an RV. There are several parking spaces at the boat ramp large enough to accommodate boat trailers, but there are only a handful of spaces, and they are reserved for those that are putting their boat into the water.

Cycling is very common in the park! All of the roads in the park are in the North section. The Southern portion of the park is considered primitive and is heavily wooded. The North part of the park includes the campground, boat ramp, and picnicking areas.
