There are a couple of steep climbs, but I think I'd more be worried about condition of the road and the narrowness of the road at some of the points on that route more than the climbs. I'm a shit climber, but as the route is relatively short I think the climbs are doable with some pain, though I'd be wanting to pick a mid to high-60's gear inch to balance getting up them and safely down too.
Here's the route with elevation:
