We took a bus to Zapokane. There may be a train, but it is slow.
There is a high peak visible Zapokane. You can easily hike that. Take a bus to trailhead or walk. Maybe 2-3 km to trailhead from town center. Hike up is fine. Easy to find your way. At the top you use chains to get to the peak. Not really scary. We were there in September. So, somewhat off season. There will be a lot of people on the mountain. Many come up from the cablecar side after riding the cable car partway up.
Mt Giewont.
We did not rent bikes so no info for you on that.
The Main Street in Zapokane is filled with great restaurants. We had great pizza and there are many that have nice roasted meats. It is a thing there.
I used maps.me for the trail. You can also look at AllTrails.com.
