Harrison Bay is a huge park, with four camping loops (3 for RVs, 1 for tents), and a large marina, located on the Chickamauga Reservoir of the Tennessee River. It is about thirty minutes from downtown Chattanooga, making it a great place to stay for awhile if you want to check out the area's numerous hiking opportunities, or if you are here to see the various downtown attractions. This would be a good park to stay at long-term as a base-camp, thanks to the numerous in park amenities and to enjoy the Chattanooga area.

Situated again the bay, the majority of the park is surrounded by water, and as such many campsites have views of the lake. Loop A is an RV loop with very little shade, and is closest to the playgrounds and picnic pavilions. Sites 7-11 and 13-14 in this loop have the most shade, with most other sites in full sun. Loop B is an RV loop with more shade on the sites on the northern end and more sun on the southern. Sites 9, 18, 22, and 25 are next to an area with poor drainage so bugs may be an issue here in the summer, and sites 29 & 30 have great views of the lake. Loop C is the last RV loop, also with a lot of shade, and sites 23-25 and 35-36 are right on the water, almost with their own private beaches. Loop D is the tent-only loop; this loop is very shaded, and the sites are fairly large and can accommodate most size tents. The northern end of the loop has clear waterfront views. Sites 13 & 14 are close to the restrooms with view of the water, and sites 15-19 have mostly unobstructed water views. These sites are very close together, but if you go on weekdays or early in the season it's unlikely there will be many other campers there.

In addition to camping, the park offers fishing, boating, hiking, a playground, a restaurant, swimming pool, interpretive center, nature viewing platform, and several picnic pavilions. In warmer months this is a popular spot for locals to come swim in the lake as well, so bring bathing suits and expect a lot of company. Most of the trails are short, however there is a 4 mile trail that goes around an "island" near the marina, and two smaller islands past the campground loops that can be combined for a 1 mile loop. These islands make excellent places to watch the sunset; the large island closest to the marina even has a bench facing southwest for this purpose.

Firewood is available for purchase at a camp store just outside the park, and residents often sell firewood roadside on the way to the park entrance.

This is not a place for solitude; it can get quite crowded during the summer between campers and locals, and there are residential areas on most sides of the lake, visible from the park. Don't come here looking for a wilderness experience. However for an outdoor vacation that has plenty of activities and is close to urban conveniences, Harrison Bay is an excellent choice!
