There are miles of trails in City of Rocks along with more in Castle Rocks State Park and many of the longer trails take you through the Sawtooth National Forest. Almo puts on a town festival called Almo Wild West days and it is always the last Friday and Saturday in June. They'll have dancing and music, magic shows, competitions that anyone can sign up for and there is talk of adding more stuff in the future. Local guide Indian Grove Outfitters offers guided horseback rides, they go for as little as 1.5 hrs up to a 6 day 5 night pack trip. Durfee Hot Springs is a fun place to visit, you can purchase day passes or buy them with a stay at the Almo Inn. The hot springs have been around forever and the Durfee's have renovated them and it's a nice place to go relax.
Tracy General has a gas station and serves unleaded fuel along with diesel, they also house a US Post Office and sell most everything you'd ever need, including crafts from the local residents.
There are no restaurants, stores or vending machines within the park. In Almo, 5 minutes from the park, the Outpost Steakhouse has a full service restaurant serving breakfast, lunch and dinner. The Outpost has great steaks and tacos! There is also a convenience store call Tracy General store where you can buy beer, gas, diesel, ATM, internet, and all other convenience store items.
The park has several fresh water sources in the park. Two of them are pump wells that are located just off the road near a parking area (one near Bath Rock and the other is near the Breadloaf). The water sources are marked on the park's map. Aside from the wells, there is nothing else in the park. If you are thirsty, you'll be traveling to nearby Almo.
The Almo Inn  was recently constructed in Almo Idaho. It is a western-themed hotel with 8 units. There are also 3 one-room cabins.
City of Rocks has approximately 50 camping sites that are spread out within the park, along the main road. Most of them feel quite seculded as they are nestled among the trees and large boulders of the park. Camping is only allowed in designated areas and a $12 fee is charged per night for each camping site used. Each site is limited to eight people and one vehicle, there is an extra $8 / night charge for a second vehicle. Camp sites can be reserved online  and reservations are recommended during the weekends when the sites fill up quickly. Otherwise, you can pay for your camp site at the Ranger station, located east of the park in Almo.
The campsites are primitive, facilities include picnic tables, bbq grills and fire rings. There are pit toilets scattered about the sites, all within walking distance but some of the more secluded walk-in sites may be a few minute walk away. There are two fresh water wells within the park.
There are no showers in the park. The nearest showers are at the General Store in nearby Almo ($4 for a shower and $0.50 for a towel rental). Another pleasant option is to visit the new Durfee Hot Springs in Almo where you can combine a shower with a hot water soak.
Garbage bins are located near the pit toilets within the park.
Camping is only permitted in the designated campsites within the park.
The primary dangers while staying in the park are the natural elements. The high elevation of the park ensures that the weather changes constantly. In the summer, hot days coupled with cold nights are the norm and it is not uncommon to experience snow during any time of the year. Wind and rain can also be extreme and dangerous to the unprepared visitor. Though coyotes and cougars are common in the area, wildlife does not pose much of a threat in the park as long as food is not left in the open.
Watch for rattlesnakes!
