I was just in the Neroberg area today on a stroll with my dog. With the exception of the Russian Orthodox Church grounds (which does not permit dogs), the area is lovely, peaceful, forested and very suitable to take a dog. One word of caution and some advice: some parts of the forested area we walked through were quite muddy, so you might want to take a towel or something to clean his paws after your walk if you'll be transporting him in your car. Also, I didn't notice any fountains or other places to offer the dog a drink, so you may also want to carry water with you - and some bags for cleaning up his messes as there weren't any gassibox bags in the area we walked.

If you park in one of the side paths going up to Neroberg, you'll find free parking (no parking meters).

Am Besten fahren Sie mit einem Bus. Ich glaube es ist die Linie 1, bin mir aber nicht sicher. Man kann am Bahnhof fragen und dort erhält man eine Info welcher Bus aktuell dort fährt.
