Increases in camping fees in the Wisconsin state park system will take effect on Tuesday.

The Department of Natural Resources said Friday that the increase in camping fees is due to the recently enacted 2015-17 state budget.

The increases vary and are based on the demand, uniqueness and the location of campsites.

Camping rates will increase between $3 and $6 per night for residents and between $6 and $9 per night for nonresidents. There is an increase in the per-night charge for electric service from $5 to $10.

Reservations that already have been made for dates in 2015 and 2016 will not change.

The price of admissions fees and trail passes also will go up, but not until the DNR begins selling 2016 stickers in December.

The price of an annual admission sticker for a Wisconsin resident will increase from $25 to $28; for nonresidents from $35 to $38; and $10 to $13 for seniors, 65 years or older.

Annual trail passes will increase from $20 to $25 and from $4 to $5 for a daily pass.

In the past five years, the parks system has collected an average $7.5 million annually in camping revenue.
