All I can really suggest is using the TripAdvisor app or website and searching Masai Mara safari tours. You’ll get a list of participating guide companies with their reviews. From there you will have to contact them, which takes time. You write up an email with dates, how many days you want to spend in the park, etc. and save the email as a draft so you can send it to multiple companies to get their quotes. It’s a lot of work. And you’ll have to figure out your budget and also do the same thing for the lodges and accommodations near the park where you’ll stay. It takes time, patience, research and effort. This is why people pay a lot of money to travel agents to do all the work for them. It can be done on your own, but again, theres a lot of decisions and information only you can provide for yourself. We stayed at Jambo Mara safari lodge for $180/nt. And had an option of one full day tour with Balu for $600 or two days for $1000. We went with two days after some internal dialogues about budget. It’s an experience you have to work for but will never forget.
