A basic slide kept my kids busy climbing for a long time as toddlers. We even bought them a toddler pool with a slide. If you go that route you might want to think about putting "bathtub" traction decals on the steps or even on the bottom of the pool as they can get slippery. If you can't find anything that fits your budget, space, etc maybe look for alternatives to "climbing". My kids have a small trampoline that they love. It has a handle and plays music and has a counting feature. They also loves games that keep them moving - Honeybee Hop, Hullabaloo, I Can Do That, dance mats. Good luck!
