This was a super fun spot to go play in the water for the day. Only thing I would change is the fact that there is no shade. The weather wasn’t great so while camping at night, it was crazy windy which was rough haha. Also, there were people blasting loud music until super late, but otherwise this is a nice spot.
Awesome place! Like some of the others said, drive in could be a bit sketchy it you’re towing or have a large vehicle - but we passed plenty of boats/RV’s, just have to go slow. There’s multiple spaces and if you’re not too specific about being near the water, you can have some decent privacy.
We camped at Irish Point at Arrowhead's designated dispersed camping area. The road around the reservoir is pretty tight, though that doesn't discourage long trailers and toy haulers. We're pretty self-contained so didn't miss any usual camp ground amenities. Our neighbors were sparse and quiet and we enjoyed the peace of this area.
Gets busy in the summer
Me and boyfriend enjoy going here in the fall and spring to get away from the city for a day or two. There is hiking right across the street. Mt Heinen which is a very strenous hike. Its over 9 miles(up and back) and over a 3,000 ft gain so be prepared if you try to tackle this summit. Anyways, the campground has some fire pits but no picnic tables. There are a few trees for shade. One part of this campground that confuses me is that there use to be a small outhouse in summer of 2018 but when I came in 2019 in march and April there was not one? When we come in the fall and spring theres no one other than us there. In the summer it does get quite a few people there. Also it gets super hot in the summertime so be sure to bring plenty of water. Good thing is you can take a dip in the cold reservoir to cool off. There's no trash services so pack it in and pack it out. A lot of people come here to party and leave trash around so i make it a point to pick it up. Please don't be those people to ruin a beautiful free spot. 💚
Be careful as the drive is a little sketchy. The water is clean and there is tons of beach area! Bring the kayaks and get paddling!
So hot and no shade. If it were not close to the water you may not have a way to beat the heat. It was beyond crowded and hard to find a secluded spot to camp away from others. Only pro is its close to town and you can swim, fish, and boat.
Arrowrock is a great and easy weekend get away. It’s only about 1.5 hours from Boise. It can get very crowded on holidays and weekends though so try to arrive early. Most people just camp out on the beach wherever you can find space. If you have a boat you can put it in the water right off the beach and camp next to it.
Honestly one of the best places close to the city. Far enough away that you still get out of service, a good view of the stars, a swim, and some magnificent overall views. Nothing like waking up here. 40 minutes from downtown Boise
Arrowrock Reservoir is a decent place to camp. The drive there is long and slow-going along a washboard dirt road, but the best part is that this spot is usually uncrowded, which is nice when you are looking for some quiet solitude. It's a steep hike down to the water in the reservoir, but not too bad. The camp sites are nice and have some pine trees, but other than that, the landscape is very desert-y.
