Triangle is popular during peak season. Reserve 2-4 weeks in advance for weekends and holidays.
Most parks have check-in after 1:00 PM and check-out by 11:00 AM. Call ahead if you'll arrive late.
Maryland weather can change quickly. Pack layers and check the forecast for Triangle.
Don't miss local attractions near Triangle. Ask the camp host for hidden gems and trails.

Cabin Camp 5 is awesome! We make an annual trek here on Thanksgiving to spend the day with friends and family. The main hall will is rustic but well furnished and maintained. The kitchen meets all of our needs and has all of the equipment you would expect. There's also a gigantic stone fireplace. And since the camp is inside Prince William Forrest Park there's plenty to do outside the cabin.

Come here yearly in December for Devil Dog Ultras. Never been disappointed. Haven't stayed in any of the bunk houses, but the bathrooms are clean and stocked, plus there's a shower.
