Getting Outdoors

This 475-acre park offers many outdoor activities for visitors to do. For those who want to get out on the water, you could head over to Silver Lake to go kayaking, boating, or paddleboarding. However, the watercraft launch for the lake is located above five miles away on Highway 504, so you’ll need to take your campervan rental from Seaquest State Park on a quick journey to reach it. The water also tends to be a little chilly, therefore be careful if you plan to go out on it.

The experience with Erick and the RV was great. Erick was very responsive and did a great job running through the many features of this new RV. The Navion RV is well equipped with nice features and a pleasure to drive, even in inclement weather.
