Absolutely no shade, dry and hot. Decent views, but a complete lack of scenery on the trail. Only company was a handful of bikers. As for a workout, rather strenuous and good workout. 1000+ ft. straight elevation gain with no break until the summit.
We went in July - cloudy day. The trail has great vistas but almost no shade. We did the Boccardo loop - western side is wide and open, switchbacks on the eastern leg make for nice views of Alum Rock canyon. Quite a workout with the 1000+ feet elev gain.
Cool 7 plus mile loop trail up to the top of Alum Rock and back down. Stunning views above the fog. Not a ton of shade so bring sunscreen. Gets very steep in parts along the Memorial section of trail.
see my review of alum rock park in general, but specifically this trail loop is a bit long, dry and exposed for my taste in hiking. mostly hilly pasture land, lots of manure and flies. rough on the knees coming down. watch out for irritated bulls.
this route affords a nice, panoramic view of the the bay from gilroy to san francisco, but in my opinion, better for bike or horseback. (or someone with younger knees than me)
