We stay here often. Everything is perfect EXCEPT we have neighbors that don't know what "light pollution" is...their campsites are lit up like a Chinese junk with LED lights..5 gallon buckets that act as lamps, LED palm trees, and string lights that "Surround" their campsite...What is WORSE is that this particular camper had some kind of device that I normally see at Christmas that projects blinking lights into the trees...all the trees near and far look as if they are raining light and blinking. IMPOSSIBLE to just look out my window and enjoy nature. It wouldn't be so bad if they would go off at 10PM..but they were on a timer and didn't go off until 4:20AM!..If there is a "quiet" time, their needs to be a "dark" time. If Boulder doesn't get a handle on this, I will not be a customer much longer. Why people want to turn campsites into the homes is beyond me....a policy about light pollution is needed NOW..!!!!

Cancellation policy
- Reservation fees are non-refundable. For campsites, cabins, lookouts, yurts, group sites, and similar stays, we charge a reservation service fee of $8.
- Standard cancellations usually have a $10 cancellation fee. Customers can generally cancel before the check-in date online.
- Late cancellation rules differ by stay type.
- Individual campsites: cancelling after 12:00am local time the day before arrival usually means a $10 cancellation fee plus forfeiting the first night's fee.
- Cabins, lookouts, and yurts: cancelling less than 14 days before arrival usually means a $10 cancellation fee plus forfeiting the first night's fee.
- One-night reservations: a late cancellation usually forfeits the full amount paid, up to the total original reservation cost.
- Modifications are allowed before the cut-off window, but fees depend on the change. Changing to dates completely outside the original reservation dates may trigger a $10 change fee. Extending or shortening a stay that still includes original dates usually has no change fee, though refunds may depend on timing and facility rules. Switching to the same type of campsite for the same dates usually has no change fee, but price differences are charged or refunded.
- Early departures may or may not be refunded. At certain facilities, partial refunds may be possible if staff can mark the site available for other visitors. No refund is given for a night if the early departure is requested after that day's check-out time.
- Security deposits are separate. Security deposits may be refunded to the original payment method if the facility is left in acceptable condition, as determined by the property.
Site capacity
- All campsites at Boulder Campground require a reservation.
Fees & deposits
- Only credit and debit cards are accepted for payments; cash and personal checks are not accepted.
Cancellation policy
- If you don't show up or cancel by check-out time the day after arrival, you will incur a $20 fee and lose the first night's fee.
- Cancellations incur a $10 fee, and last-minute cancellations may lead to forfeiting the first night's fee or the entire amount for one-night stays.
Fires & fuel
- Firewood must be either purchased on-site or collected locally to prevent invasive pests.
