Colossal Cave Mountain Park

Managed by Pima County, this established campground operates year-round with sites priced at $10-$15 per night. Access requires navigating rough paved roads with numerous potholes throughout the park, making high-clearance vehicles advisable for reaching all areas.

The campground includes multiple sections with varying configurations. La Selvilla sits in the back canyon area where most sites feature shade trees and flat tent pads alongside picnic tables and fire rings. Robbie B. notes "plenty of room and spots are not too tight and most had shade trees." The facility accommodates RVs up to 25 feet, though RV spaces consist primarily of cleared pull-in areas. Gates lock at 4:00 PM, restricting entry and exit until morning.

Water faucets, pit toilets, and trash service serve the camping areas. Fire restrictions may apply during certain periods, with policies not always clearly communicated in advance. Cell service remains limited with Verizon showing one bar coverage. The forested terrain provides some tree coverage uncommon in desert camping, and campers occasionally spot deer in the morning hours.

Beyond camping, the park offers cave tours and hiking trails including connections to the Arizona Trail. For those exploring the broader region, camping near Vail provides additional options in the area.

Weird Hours but quiet in nature

Pros: 

Good price $15! 

Choose your site

Quiet

Out in saguaros

Campfires allowed (get wood before)

Cons:

Gates for entry/exit closed 4pm-8am!

Bathrooms far from sites

We had a cute site with a little bridge over to a tent space, fire pit, and picnic table. There were 3 other sites nearby and only one occupied with a nice neighbor who had been there for a few days and no one else. There are a few more sites a bit farther down and even farther down the road is where there's more of a party atmosphere but you need the right vehicle to get there.

Would stay again except for the weird hours of access so plan accordingly! Seems like in the dessert would want to be out early and late for cooler hiking times so could be a deal breaker.

Great spot just off Arizon Trail

Nice spot just off the AZT, stayed while on a bike trip on the trail. Camped in the La Selvilla section in the back of the canyon. Plenty of room and spots are not too tight and most had shade trees. All had flat tent pad, table and fire ring. There is a group spot with a pavilion that has running water, and pit toilets. Verizon was one bar, got a few calls out but text would not work. They do lock the gate at 4:00, so once in, you are there for the night. Only one other group when we were there. Would go back for sure.

Amazing, beautiful, good price

Loved this camp site. You have to go into the cave gift shop to pay. They do close gates at 4. Was only 10$ for a tent spot.

Not bad for the price

Super cheap. The sites and restrooms needs some tlc. We were the only ones in the tent camping area which was a plus. This campground is good if you r doing tours in the day or just need a trip to get out.

Not for everyone but we Loved it!

I want to give this place 5 stars but not having a natural water source and locking the gates at night don’t get ya 5 stars 🤓 ...I understand their reasoning behind locking the gates however; bad humans out there that come in late at night and trash the place and don’t pay the measly $7 a night to camp - so locking the gates prevents that. Anyway, the picnic tables were nice and the entire canyon was just beautiful. It’s also a simple drive to Saguaro National Park (East) as well. We saw a deer in the morning too which was cool being that it seemed so out of place in the “desert” ha ha...we will definitely go back. Good times.

Spontaneous Campout at Colossal Cave Mountain Park

I took my Girl Scout daughter and her bff-first time camper to spend the night at Colossal Cave MP last Saturday. Living about an hour away, called and was told plenty of sites available, to just come on up. Arrived to find the campgrounds in dire need of maintenance and roads in pretty cruddy condition. Was informed of no campfires after checking in. :( Went in search of a site to find tentsites doublebooked between Sierra Club and a Girl Scout troop! Serendipitously the girls invited us to share - being sisters to every scout! :) Group site was next to parking and pit toilets and had water, grills and cement picnic tables were all available there. Cost was DEFINITELY a plus here- $7.50 per night!

Better as Day Use or Group Campground (Don't Trust the Website)

I hope this is the hardest campground review I ever have to write. The visit to Colossal Cave Mountain Park started pretty terrible but the property manager/caretaker (Gary) saved this review. Let me start from the beginning.

Upon arrival we were checked in and told there were fire restrictions in place so we wouldn't be allowed to have a fire. I told them that's not what their website said and they argued "well we tell everyone when they call in". Needless to say, I wasn't told when I reserved my spot that there was any restrictions. (and even now, when checking the forestry websites and county fire restrictions they all direct me here (https://firerestrictions.us/az/az-pima-county/) and the specific location of the campgrounds doesn't seem to be under restriction nor can I even determine which specific area to look at. The park said they were part of the forestry service but that area seems to end East of there)

We were told that with our "RV" we would be located at El Bosquecito. We drive to the grounds and find out it's a walk in group site with a small cul de sac with 2 small dirt pull outs to park. I called the caretaker and asked where exactly we were supposed to be setting up so he drove down to meet us. It became very clear very quickly this spot wasn't going to work and this is when he told us they had overbooked their RV spaces (they only have 3) and they were trying to find somewhere to put us. He offered to let us stay in the Day Use area and that is where we spent the next 2 days. (and over the next few days we ran into him a few times to get suggestions on things to do, etc)

Like any camping trip we went exploring to see what the rest of the park looked like. Here is what we found:

  • All of the single campsites are currently closed (and have been since late last summer). I'll post a picture of one of the spaces but you can't actually camp there at this moment.
  • The "RV" spaces are big enough for a sizable RV but that is all there is to them… a cleared out pull in space.
  • El Bosquecito is actually a pretty neat group campground if you don't mind carrying your gear in. There was some tree coverage (it really doesn't get better in the desert). There were BBQs, water faucets, bathrooms, and fire pits. However, there were some weird potential hazards like exposed pipe and open water trenches.
  • Most (if not all) of the advertised things to do were shut down or unavailable.
  • Petting Zoo - They are between ranch vendors so this was not available,
  • Tortoises - They were hibernating (not available)
  • Butterfly Garden - There were a few but it was out of season.
  • Gold Panning - Available, but you have to but the bags of dirt to pan with from the gift shop.
  • The Terrace Cafe - This was open but it's not a restaurant (it's not even in the building). It's a covered "stand" that you order at then there are a few picnic tables in front of it next to the gift shop.
  • The Museum - Currently Closed
  • The Bats - Out of season
  • There are a few trails in the park (Path of Ancestors, Bundrick, and the Arizona Trail). We did parts of all 3 but Path of Ancestors was my favorite. It has information boards along the way talking about the Hohokam tribe.
  • Every road in the entire park is REALLY rough. They are paved but there are potholes everywhere. I wouldn't take a super low clearance car through the park and you won't make it back to La Selvilla (if it's open) without high ground clearance and 4 wheel drive.
  • They do have bathrooms (ours also had a hand washing station), there were trash cans in all of the usable areas, lots of BBQ stands, and picnic tables. In the group campground and the day use area there were also water faucets.

While we were there we also did the Regular Cave Tour and it was really neat. Dane was our tour guide and he was fun to listen to and very informative. It really was 70 in the cave and with it being in the 50s/60s outside we went in overdressed and ended up really warm. Trust the temperature they tell you! If you have any choice in the matter stay towards the front of the group. We went down with 17 people and there were a few times we couldn't hear the guide or see what he was pointing out because we were so far back.

So overall… I wasn't super impressed this trip. However, Gary gave us a great impression and explained a lot of the "problems" were parts of the park in transition. I totally believe this park could be really neat when it's running as intended. Until then - I strongly suggest you know exactly what you plan to get out of the trip and call ahead to ask for clarification if there is anything in particular you want to see. Their website is NOT kept up to date so it is not a reliable avenue for information. If you are just looking for a neat day trip or a group campground you may have more success than we did but it all depends what you are looking for. I hope to go back in the fall to give it another try.
