Pros:
An unobjectionable, sparsely wooded course with decent elevation and lots of views of the Tennessee River.
-Amenities: Turf over gravel tees are okay if a little uneven, grey Chainstars (what is Chattanooga's obsession with these baskets?), good tee signs with maps and distances, course map at the kiosk. Enough benches, I think.
-Views: The water will only come into play on a terrible shot, but it sure makes for a scenic backdrop. This is a course that is actually literally on an island--enjoy almost constant views of this spacious section of the river.
-Beginner Friendly: The length is enough that they won't shoot even, but this would be a nice place to introduce newer players. It's pleasant and you can recover from an early tree without being totally dull fields.
-Shot Shaping/Gameplay: A very typical shaping course that receives a boost from gentle elevation throughout. Every hole is basically the same environment--sparse large trees that suggest a wide fairway but allow for a lot of flexibility. With the exception of (9), every hole here is entirely scramble-able due to this spaciousness. Some easier ace runs under 250' are balanced with longer par-3s needing a touch more juice and forcing you to consider the OB walking path that winds throughout the island. Two par-4s are out here, with (9) being the star hole for its tricky approach to a small, wooded green near a steep dropoff. (15) is also a memorable hole, a gentle 350' downhill towards the water, and (10) is the quirky hole, a steep downhill and sharp right that's deceptively difficult.
-"Friendly": My label for the combination of easy-to-play, navigable without a map, well kept up, and hard-to-lose-discs.
Cons:
Though Dallas Island is a pleasant park, it lacks any unique features or compelling variety.
-Length: Only one hole tops 400'. This prevents anything particularly interesting from happening on the fairways.
-One Environment: The foliage/biome doesn't change throughout. Again, combined with the length, this makes one hole feel like the other and doesn't leave you impressed or with a feeling of accomplishment.
-Multi-Use Hazards: The first is the omnipresent walking path. Expect to pause several times during a round for walkers and joggers to pass. The second is RV plots. There weren't very many vehicles when I played, but during busier months I could imagine quite a few RVs out here that you'd have to be really careful to avoid.
Other Thoughts:
Dallas Island is a solidly Typical course with the added pros of a little elevation and constant views. It's right on my border of 2.5 and 3.0, and for now I've followed my rule of rounding towards the middle when I can't decide. It's exceedingly pleasant to play, not a destination course, but one that should get a lot of good use from locals.
