The closure gate for Tioga Road is east of the parking lot for Tuolumne Grove. Tuolumne Grove will be accessible in January.

Mi scuso per il ritardissimo nella risposta ma vedo solo adesso il messaggio; anche io concordo che la scelta dipende dal tempo che hai a disposizione, non mi ricordo quale sia il più corto(quello che ho fatto io) ma nelle indicazioni è ben evidenziato il tempo di percorrenza di entrambi. La sequoia a tunnel si trova in quello più breve ma, non mi farei condizionare da questo nella scelta perchè non è poi così bella ed emozionante come le altre sequoie vive.

Yes. The trail head will take a little bit longer than twenty minutes, especially going back up.

It is a tarmac road, so a stroller should be ok, but it is very hilly

It's easy to find and the trail head is well marked, and the trail itself is paved. It's easy going down, but make sure you bring enough water, as the hike back up is a bit difficult. An 8 year old should be able to handle it.

Tuolumne Grove is open year round.

Yes, on the main trail (there are some side loops where dogs aren't allowed). From the Yosemite NPS website: "There are a few additional (very obscure and unsigned) places where pets are allowed: - Wawona: Wawona Meadow Loop, Chowchilla Mountain Road, and Four Mile and Eleven Mile fire roads (but not the Four Mile Trail in Yosemite Valley). - Hodgdon Meadow: Carlon Road from the trailhead to Hodgdon Meadow and on the Old Big Oak Flat Road from Hodgdon Meadow to Tuolumne Grove parking lot."

It's a paved road... very unlikely you will encounter any wild animals, as too many stupid humans around :)

Tuolumne Grove of Giant Sequoias is open year round. The closure gate of Tioga Road is past the parking lot for Tuolumne Grove. Note that this is a great question to post on the active TripAdvisor forum for Yosemite National Park. Several folks would offer their advice & feedback. This Q&A feature is seldom viewed.
