Sporting Events- My favorite type of activity to travel for or to attend while traveling! My experiences include the Women’s World Cup 2015 and the French Open 2017. Also many American sporting events! While sporting events can be a more expensive activity, they are worth the bucket-list experience if you are a sports fan!
Scuba Diving- I am a recent PADI certified scuba diver. Though scuba diving can be a bit of a pricing activity, I have found that if you enjoy traveling to location that are near the ocean it is a great activity to get into. Also looking into getting certified in another country can make it much cheaper (Thailand is a great option) Once certified the hobby can become very fun and and affordable activity to enjoy while traveling. To become certified it is a 2-3 day course and can cost anywhere from 200$-600$ US dollars depending on where you are in the world, I got certified in Sicily, Italy where it was rather inexpensive compared to the US. I have also scuba dived in Thailand, and they have the cheapest rates to get certified as well as many great beginner dives! Thailand is also great for experienced divers as well.
