For more comprehensive information, purchase the excellent guide, Sweet Spots, by Jerry Painter and Matt TeNgaio.
One of the original hard men, Dave Bingham, has written Underground Idaho which also contains the latest information concerning climbing at the Fins and other local crags.

Located at the southern end of the Lost River mountain range, the Fins offer climbing unlike any other in southeast Idaho. On vertical to slightly overhung walls of immaculate limestone, most routes here feature positive edges and secure pockets. The rock is somewhat sharp, but the texture is excellent. Chances are, your tips will wear out before your forearms.
The walls at the Fins have seen significant new development as of 2012, so there are many more routes than I have descriptions for. Dave Bingham, Matt TeNgaio, and Jonathan Siegrist have been the major contributors lately. We all owe a huge thanks to these guys and the earlier developers for their hard work and vision.
Morning sun, afternoon shade. When it's too hot to climb elsewhere, excellent conditions can be found at the Fins in the afternoon and evening of even the hottest summer days.

Getting There 

South of Howe on Highway 33, turn west at a gravel pit into Eightmile Canyon. Keep right on the dirt road as it enters the canyon. If you've got a four-wheel drive vehicle, drive five miles to basically the top of the mountain and park in the established parking.
For low-clearance vehicles, you'll need to park in the lower parking (about 3.5 miles from the highway).

Bare Knuckle Boxer 5.13b 8a 29 IX+ 30 E7 6c  ID : The Fins : ... : Mothership Sector
A wicked extension to Marc's classic, 'Bushido' 13b. After a good rest carry on through rad pocket pulling to the right side of the huge hueco at the top of the wall. Relatively straight forward climbing, adding a nice pump to the top of Bushido. Probably mid 5.12 in itself -- hard to say that after a good rest it really adds any substantial difficulty, but it certainly adds quality. ...[more]   Browse More Classics in ID

On the upper parking: Clearance isn't necessarily an issue as a reasonably skilled driver in a Subaru can make it. If you have low-range use it, if you have a transmission temp warning light, pay attention to it, if you don't, plan to take a rest or three on the way up to give your tranny a rest (automatics). Watch your engine temp too, mine was fine on the first run up, but was the limiting factor on the second time up (hotter day). My vehicle is an AWD Chevy Express. I know one Jeep Cherokee had to turn back due to tranny overheating.

Rattlesnakes: There is at least one in the rocks just above the camping; watch and listen when 'getting rid of your coffee'. Running on the dirt road, a climber on a rest day came very close to one. It's a good idea to keep a bite extractor kit with you. See photo - very center...

Dont attempt driving up the hill unless you have 4wheel drive and know how to drive a 4wheel vehicle. And old cars can easily overheat. Park at the low parking or hitch a ride.
