In reply to NateDangerJones:
Saas-Fee/Grund is hard to beat for your purpose.
There are half a dozen or so 4000m peaks there that would be very doable with your experience. I assume, living on Skye, you’ve scrambled much of the Cullin.
Options include (in order of difficulty)...
Jegihorn 3000m peak - via 2hr walk/scramble up or longer via-ferrata or bolted rock climb.
Allalinhorn 4000m peak - via 1.5-2hr walk up from cable car over easy glacier terrain or 4hr trek up from a Brittania hut mostly on steep snow with a well protected rock pitch near summit, descend the short way to the cable car.
Lagginhorn 4000m peak - 4hr up easy glacier to ridge scramble then exposed snowy top.
Weismies 4000m peak - 4hr up from the Amagela hut, no glacier, mostly scramble up rock ridge that may have some snow about. The quicker way from Honsass is more dangerous these days.
Stralhorn 4000m peak - 5hr up, long snowy walk over glacier. Usually not too cravassed.
Alpubel 4000m peak - 3hr up possible from an early cable car breaking off from the Allalinhorn route. Descent to Langfulh can be tricky with crevasses extra care needed.
Nadlehorn 4000m peak - Long hard hut approach, peak tops out at over 4300m so accimitation important. Crevasses on glacier tend to run parallel to route so extra care needed. Rock pitch at summit may require placing gear.
