Find places to stay in Indonesia

Insurance that covers climbing

Most standard travel policies exclude rock climbing, and a lot of them exclude riding a scooter too. Check your own policy first — and if it does not cover you, this is the one I use.

  • Covers rock climbing, which most standard travel policies exclude
  • Buy it after you have already left home, and extend it monthly if you stay in Indonesia longer
  • Emergency medical cover and evacuation, which is the part that actually matters
