It wasn’t the best start into the day. Even mediocre cafés in Waikiki are very busy in the morning, and checking other cafés for shorter queues didn’t make it better.
Also, we recommend to inform yourself well about the buses in Oahu, or even better, ask the locals. There are around 20 bus stops containing “Diamond Head”, but just one is the correct for doing the famous hike. Being lost, we did our very first Uber drive and didn’t regret it.
Diamond Head is a volcanic tuff cone (dormant), a national natural monument and a very touristy place. Doing a relatively easy hike (for Swiss standards) from the inside of the crater up to the cone rewards you with great views over Honolulu.
