Sunny during the morning, shady in the afternoon. This is often a windy area. All routes except Fly by Night, Positively Negative and Spraypaint can be done with 50 Meter rope.
Drive past Heise up Kelly Canyon Road. After road turns sharply left, about 200 yards up the road there is a small parking area to the left of the road, or further up the road, before the second cattle guard. Hike up the hill on the left of the road. Wall is visible from the road.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Paramount Rock:
I checked out the route mentioned in my previous comment today. It's scary. very dirty and chossy at the top. good gear to about half height and then nothing. i ended up bailing onto the bolt line because it just wasn't worth it.
currently living in rexburg and me and my wife have been to paramount twice now. but it is a pain getting up to the cliff. mountain pro, and rock climbing.com say follow obvious trail from parking area but where is that? we have to go up the huge rock slide cuz we havent seen it anywhere. if anyone could be kind enough to let me know where the trail is itd be a huge help. i guess some local has his 8 year old kids walk up the trail so its obviously not the huge rock slide weve been hiking up.
The parking area is a more or less flat depression on the north side of the road. The trail starts just past the north east end of the parking area. Last year there was a metal fence post at the beginning of the trail. There used to be a sign on it but the sign went missing. The first forty feet or so has ball bearing like gravel and it's easy to lose your footing if you are not careful. Rumor has it that a prominent local climber slipped on that section injuring his ankle and ruining his climbing career.
I was climbing that shale the first few times and it was a pain. Then I realized instead of parking on the East side of paramount, you park on the South side, or directly below it and follow a trail that wraps around to the southern most climbs... A lot easier this way.
I haven't been to too many places outside of Utah and Idaho for climbing, but I have noticed the bolts on most of these routes are quite a bit more spread out than a lot of the newer, surrounding areas.
The rock is nice to climb on here and its good to get on some longer routes!
