This is important to get right, as leaving behind any essential gear can be expensive or limiting. Even something as small as one forgotten carabiner can be a significant setback.
Your gear checklist obviously depends on the type of climbing you’re doing. For sport or trad, check your guidebook to get a sense of what length rope and slings you’ll need, and how many quickdraws/nuts to take.
Whether or not you’re bouldering, a crash pad can give you extra reassurance on routes with awkward starts, or long runs to the first bolt.
Further safety can be achieved with maillons and clipsticks, helping give you more peace of mind on routes.
Multi-day climbing trips can quickly take their toll on your hands, so don’t forget to pack lots of climbing tape and skin repair balm.
And last but not least – take plenty of water! Hydration bladders are ideal for outdoor trips, giving you easy access to a decent amount of fluid, without lugging heavy bottles around.
