MAKE SURE YOU TAKE EXTRA WATER, OR FILL YOUR TANKS. We stayed three nights in T-loop, site 42 in mid-April. Only a handful of sites have any shade, so be sure to request shade when making reservations and you may get lucky like us. No water at sites, any only some have electricity. Potable water at bathroom unless pump goes out. It was towards the end of the busy season, so only one of two bathrooms were open. But the one bathroom was clean. Lots of angler groups, so a little noisy at night, but all in all they were respectful. Out last night the water went out and all bathrooms in all loops were closed. Apparently this can be common with pump going out. Understand things happen, but communication was horrible. Just a sign on bathroom that it was closed, no water. No indication that we should go to the visitor center for toilets, sinks. And the next morning the water was back on, but only put up boil advisory sign at CG entrance, not at bathrooms. So people using sinks without knowing water was compromised. Again, awful communication, especially when this happens with some regularity. ONLY AT&T SERVICE, with Wi-Fi at visitor center one mile away.
