How to go in Oase by common transports
I know that we can find the information in some others posts, but the reason why I've never visited Oase before is that it looked very complicated to go there by train from FrankfurtHBN.
In fact, it's easy. This is my experience:
I arrived in Francfurt around 8 am, and my plan was to go again in Mainhattan, because it's very easy to go there by tramway.
But in the forum, I've read that Oase is open at 10 am, so I took the decision to change my first plan.
From FrankfurtHBN, I bought a ticket to go to Friedrichsdorf. The ticket costs 4.35 euros and I took the S-Bahn 5 (direction Friedrichsdorf via Bad-Homburg).30 minutes to go there.
Arrived at Friedrichsdorf, there was only one taxi. A guy took it before me. Fortunately, the bus S53 was here. It's free if you keep your S-Bahn ticket with you. The next stop is Burgholzhausen. It's in a village. It's scary, because even a Saturday, there is nobody in the streets, like a ghost village. I knew that I had to found Ober-Erlenbacher-Strasse. I was in a bit panic, but in fact, it's easy to find. Straight away after the bus stop. Then I crossed a way without nothing around. Only fields of wheat of things like that. But after 15 minutes of walk, here was Oase. Ouf. With a taxi, it costs 10 euros from Oase to Friedrichsdorf station.
