If you are referring to us 41, I know you can drive. I believe there are paths both ways. That would be a long walk. I think I recall passing joggers on that route.

Didn't realize they had concerts there.

There is a little area/beach where some people swim but I don't think that it is encouraged. The park has walking/biking paths along the waterfront as well as tennis and pickleball courts and a children's playground. Laishley Park, on the east side of 41, has water fountains for children to play in and around.

8am-8pm 7 days a week

No but at one end of the park is a boat club with berths (I do not know what they charge) and at the other end is a hotel that has a few places to tie up. Just a short ways farther down just beyond the end of the parks toward Charlotte Harbor is Fisherman's Village and there is a marina and there are a few places to tie up outside of Harpoon Harry's. The other direction, between the north and southbound Tamiami Trail bridges is the Sheraton Hotel and Tiki Bar. Haven't been there but they should have a few places to tie up.

Yes leashed dogs are allowed. Doggie waste disposal bags are available. Some of the park is under construction.

Pickleball starts at 08:00 every day. Place is packed and not clear on the protocol to get on the court. Suggest you show up. Place is empty in early afternoon.

Hello, there is no charge to park and yes I believe there is handicap parking. A fishing license is necessary in Florida.

Ask about fishing licence you will have to check with FL Fish & Game. Gilchrist Park closes for a year any day now. Expected to open again Dec. 2017. I suggest you check into Laishley Park on PG city website. I think the fishing pier is accessible.
