Any good mountain climbing spots

I'm thinking about going to Marrakech to climb Mount Toubkal. I haven't climbed a mountain in 5 years and I want to climb again. But until I save some money to go to Marrakech (I feel guilty asking my parents), I wanna know any mountains/small mountain ranges in the UK I can climb because I ain't climbing a 4,200m elevation mountain after not climbing for 5 years.

Just here for the adrenaline junkies like myself - leave any advice y'all can.

This is just one of my ideas for what I can do this summer to take my mind off exams, my other options are to do a UK city tour or go backpacking or going to Croatia for like a week.
