That 7 or 9 dollar fee is per day that you are camping plus the camping fee ?

Yes, that is correct.

You will have to pay a day fee, plus the cost to camp. The day fee will not apply if you have an annual parks pass.

Yes

But a parks pass it's worth it

Yes, you do have to pay the day fee to gain entry to the park as well as your camping fee. If you plan on camping or visiting Colorado State Parks more than 10 days you may want to look into a yearly pass: Annual Parks Pass - $70 per vehicle. Our Annual Pass can now be purchased at any time of year and is valid for a full 12 months of use. The pass is good through the last day of the month, one year from purchase.

Day fee plus camping fee.

Honestly i don't know, o only stop there to refill
