I'm planning to visit the part the 3rd week in March. Would you please clarify these questions. Can we take camping equipment? Are there hiking trails? Can we take our bikes? Can we swim in the lake during this time if the weather permits? Thank you

Yes

Camping tent and rv allowed. Water and electric and the electrical is both 30 n 50 Amp in each box. Has several hiking trails. Dog friendly. Please pick up after your pet. You wouldn't want to step in some one else's dog poo. Small airstrip. Call ahead. Paved roads for biking. A lot if paved roads. Nice park. Been camping there for years.

Yes there are trails as well as many paved roads for hiking and biking. Camping equipment is allowed in overnight camping areas. These can be reserved online. I do not know when they open the swimming area.
